Jack Hatem has served as the head football coach since 2010. Prior to that, he had spent five seasons as an assistant football coach at Denison. In 2011 Hatem guided the Big Red to a 5-5 record and a 4-2 mark in the North Coast Athletic Conference that resulted in a third-place finish in the league standings. In the spring of 2012, Hatem and his Denison staff were selected to coach the South team at the third annual Ohio Army National Guard Senior Bowl. On April 13, the South squad, coached by Hatem, defeated the North, 21-7 at Columbus Crew Stadium.
Prior to coming to Denison, Hatem spent 13 years as a high school football head coach. He also served three seasons as the head baseball coach at his alma mater, The University of Rio Grande. Hatem graduated from Rio Grande in 1982, earning his bachelor’s degree in health and physical education. He also holds a master’s degree in physical education from Ohio University (1992). A two-time Ohio High School Football Coach of the Year, Hatem brought 25 years of coaching experience and 13 years as a head coach at the high school level to the Denison program. A native of Lancaster, Ohio, and a graduate of Fisher Catholic High School, Hatem was named head football coach at Fisher in 1992. Over the course of three seasons, he led the Fighting Irish to a 22-9 record, including the program’s third undefeated season in school history in 1993. That year, Hatem earned his first Ohio High School Coach of the Year recognition and guided his Fisher squad to its first-ever state playoff appearance.
From 1995 to 1997, Hatem served as head football coach at Highland High School in Sparta, Ohio, and in 1998, he took over a struggling New Albany High School football program, quickly turning it into one of the top programs in central Ohio. Hatem was named Ohio High School Football Coach of the Year again in 1999 after guiding New Albany to a 9-1 record, the program’s best season dating to 1966.
In addition to his accomplishments on the football field, Hatem also has had considerable success on the baseball diamond. A former baseball standout at Fisher Catholic, Hatem served as head baseball coach at Rio Grande for three seasons, shortly after his graduation from the college. While he was an assistant football coach at Bishop Watterson High School in Columbus, Hatem also served as head baseball coach there. In 1991, he led Watterson to its second state baseball championship.

As a plant systematist my main research focus is the fern family Ophioglossaceae, commonly called the adder's tongue ferns. I use both molecular and morphological evidence to infer evolutionary patterns and processes within the family and to establish classifications that reflect evolutionary history. Currently my research focuses mainly on projects in the adder’s tongue half of the family, although I am still involved with research on Sceptridium (the grapeferns) and Botrychium s.s. (the moonworts). I use DNA sequences to examine phylogenetic relationships among species of Ophioglossum s.s. (the adder’s tongue ferns) and to explore within-species variation in Ophioderma pendula (the ribbon fern). Central to nearly all of my research projects is the difficult to define interface between species and populations.

Jessen Havill joined the Denison faculty in 1998, having spent the six prior years studying at The College of William and Mary in Williamsburg, Virginia. Dr. Havill teaches courses across the computer science curriculum, in both theory and systems, although his specialty is in theory-related courses like Discrete Mathematics, Data Structures, and Algorithm Design and Analysis. He is also very interested in developing courses that explore connections between computer science and other disciplines. In 2009, he developed and started teaching a new introductory computer science course (CS 111: Foundations of Computing for Scientific Discovery) that introduces the principles of computer science in the context of scientific modeling and simulation. In 2012, he and Jeff Thompson, a colleague in the Biology Department, began teaching an interdisciplinary computational biology course (CS/BIOL 309: Computational Biology). In 2013, Dr. Havill was awarded Denison’s Charles A. Brickman Teaching Excellence Award.
My research largely focuses on the design and analysis of algorithms for online network routing and machine scheduling problems. An online algorithm is one that processes its input one element at a time instead of all at once like a traditional algorithm. For example, an online room scheduling algorithm would have to assign a room to each event as it “arrives” without knowing what events might need to be scheduled later. Online algorithms usually cannot come up with optimal solutions due to their lack of knowledge about the future. Instead, we try to design algorithms that find solutions that are provably within some factor of optimal. I have also recently developed an interest in problems in computational biology.

Prof. Heft has been on the Denison faculty since 1976. His graduate training was in an interdisciplinary program concerning the relationship between psychological processes and the environment. At Denison, he has been a recipient of the Charles A. Brickman Award for Teaching Excellence. He has also been elected as a Fellow in both the American Psychological Association and the American Psychological Society. Dr. Heft serves on the Editorial Boards of the journals "Environment & Behavior" and "William James Studies," and he is the Book Review Editor for the "Journal of Environmental Psychology." He teaches courses in environmental psychology, history and systems of psychology, and cultural psychology.
Prof. Heft's scholarly interests primarily concern topics in the related areas of environmental and ecological psychology. His book "Ecological Psychology in Context" (LEA, 2001) elucidates the theoretical and philosophical foundations of ecological psychology and some of its connections to current work in cultural psychology.
Much of his research has examined the process by which humans find their way through the environment, with its focus on identifying the environmental information that is utilized in learning a path or route. On-going research in this vein is attempting to understand how this route knowledge can be employed to promote understanding of the overall configuration of a place. He has also conducted research in the past on the perception of affordances (i.e., the perceived functional meaning of objects and environmental features), the development of children's navigational skills, environmental aesthetics, and the effects of noise in the home on cognitive development.

Many proteins in the cell are large structures composed of several smaller polypeptides called subunits. These subunits must be properly assembled together to produce a functional protein. A better understanding of how large protein complexes are assembled could lead to new therapeutic targets for the treatment of many diseases including cancer. My research focuses on the assembly and targeting of the Vascuolar H+-ATPase. V-ATPases are essential for acidifying intracellular compartments. Several proteins have been identified that act as assembly factors for the V-ATPase and I am interested in determining how these factors interact with each other and with the V-ATPase to produce a functionally assembled protein. In addition, I am interested in determining what factors are necessary for targeting the V-ATPase to different cellular locations. The V-ATPase is normally found in the membranes of lysosomes, the Golgi Apparatus and vesicles. However, in certain cell types including kidney cells, neurons, and cancer cells, the V-ATPase is found in different cellular locations, including the plasma membrane, and this has functional significance for each type of cell. I am interested in identifying the proteins that interact with V-ATpases to determine their cellular localization.

One of the things that excites me most about Physics is our continuing struggle to develop a better understanding of how the world works at a fundamental level. We Physicists also work to apply that understanding to complex, real world problems. For me, one of the great pleasures of Physics is finding creative ways to address these challenges. I enjoy teaching Physics and Astronomy at all levels in our curriculum.
Black Holes and Cosmic Jets
I study distant active galaxies. Active galaxies are extremely energetic galaxies, giving off so much energy that they can be viewed from billions of light years away. All of the unusual, energetic behavior in an active galaxy can ultimately be traced to its galactic center or nucleus, a region only a few light years across. These objects are therefore often called "Active Galactic Nuclei" or "AGN" for short. It is now believed that all AGN have, at their center, a super-massive black hole that is millions or even billions of times the mass of our Sun. Matter falling inward toward the black hole dramatically releases energy to generate the phenomena we observe.
There is a sub-class of AGN that have strong jets of plasma which stream outward from the galactic nucleus and are visible at radio wavelengths. These radio jets come in a number of morphologies with the most spectacular maintaining collimated flows for tens or even hundreds of thousands of light-years before terminating at hotspots in large, inflated radio lobes. I study these jets to understand their physical properties and how they are created by the super-massive black hole and accretion disk of in-falling matter at the center of the galaxy.

My goal as a composer is to create music that is lyrical and driven by narrative. My music tends to be tonal centric, yet filtered through a contemporary lens. I write both instrumental and vocal music in many different genres for solo, chamber, and large ensembles. Currently, most of my work tends to be commissioned for specific performers or ensembles. I write for young musicians and professional artists for a variety of occasions, including solo recitals, centennial/bicentennial celebrations, festivals, and international tours. Each composition clearly expresses my “voice,” reveals my “fingerprint.” Being raised in an artistic Chinese family in the middle of the United States has influenced my music, just as my formal training has refined my compositional skills.

My current research interests include (1) gender differences in social behavior, (2) the social influence processes used to change others' attitudes and behavior, and (3) the personalities of attorneys.
First, I am interested in gender differences in a variety of social behaviors, as well as differences in the social evaluation of women's and men's behavior. My research in this area has examined the content of attitudes toward men and women, gender differences in interaction patterns, and the appropriateness of women's and men's emotional reaction to life events. My current research projects focus on the social consequences of women's and men's emotional expressions during job interviews and political campaign speeches.

Social Influence Processes
My second line of research addresses the social influence processes that individuals and groups use to change others' opinions and behavior. I am particularly interested in the conditions under which a minority opinion holder can influence the opinion of a majority, and the social influence processes by which a minority and majority opinion holders exert their influences. My recent work on these issues has been in the context of psychology and law.

Personalities of Attorneys
The third line of research examines the personality characteristics of attorneys. In particular, I am interested in individual differences between trial and non-trial attorneys as well as gender differences. To examine some of this research click here. We have developed a webpage that summarizes the research we have conducted on this topic and contains a Psychology and Law Research Guide to articles about various topics in the field of psychology and law .

Professor Jacobsen has been teaching full-time at Denison since 1984. He received the A.B. in Latin from Frankln and Marshall College, and the M.A. and Ph.D. in Classics from The Ohio State University. Professor Jacobsen teaches Latin and Greek, and a wide variety of courses on the history and culture of ancient Greece and Rome. As a scholar interested Roman poetry, specifically in the work and the reception of the poet Ovid, Professor Jacobsen's most recent work includes an essay in the book Ted Hughes and the Classics, published last year by Oxford University Press, and an article on Ovid's influence on the contemporary Irish poet, Ciaran Carson, published in the journal Classical Outlook.
Specifically, my interest is in the discursive production of "public health anxieties" and the ways systems of race, nation, and gender frame "risky bodies" and "at-risk bodies." In analyzing the 2002-03 multi-country outbreak of SARS (severe acute respiratory syndrome), I trace a genealogy of SARS scientific progress at primarily cellular and genetic levels which serves as a backdrop for political, regulatory, and popular science discourses. In addition, I am currently interested in "nail salons" as discursively produced sites of "public health anxiety," fear, and contagion.
Broadly, my area of scholarship aims to make connections across terrains of “natures” and “cultures.” Much of the public perceives the biological sciences as wholly residing in the natural world. In other words, the scientific study of the living natural world operates with an objectivity that produces value-free knowledge that is untouched by “culture,” that is without historical, political and economic contexts; scientific knowledge is an unblemished reflection of the natural world. On the hand, there is an analogous and equally troublesome misconception of “women’s studies” as wholly residing in culture, that is operating within a social constructionism that problematically annihilates subjects, objects, and “facts.” While neither of these caricatures does justice to these (inter)disciplines’ intents, they allow us to trace needed connections between feminist critiques and biological inquiries. Feminist science studies aims to examine and embrace dimensions of reality between the social and the material.

Dr. Kaplan started his environmental career at Oberlin College, where he was one of the very first ES majors, and he also majored in Poli Sci. After college, he went off to Northern Virginia to work for a quirky company as a computer systems analyst. After two years there, he moved on to the Institute for Environmental Studies at UW-Madison, where he earned his M.S. in Land Resources and a certificate in Energy Analysis and Planning. He was the computer techie guy for IES during that time as well. Then he was off to Chapel Hill for his Ph.D. in City and Regional Planning from UNC. His dissertation was about how to get electric utilities interested in solar (photovoltaic) technologies, relying on a national survey of managers. Dr. Kaplan was hired as the founding director of Denison's ENVS program in 1993, and finished his Ph.D. requirements just weeks before moving to Granville on New Year's Eve that year.
Kaplan's courses include Environmental Politics & Decision Making, Environmental Planning and Design, Environmental Dispute Resolution, the Practicum and Senior Project classes, and his new love, Farmscape: Artistic Perspectives on Farmland Preservation. His research spans a variety of areas that are all connected by the question, "How can we best relate to our environment?" In working with the U.S. Geological Survey, his efforts focus on creating an organizational culture that places this agency at the forefront of environmental science. In working with photography, his work deals with views of the environment that might make us think differently about who we are and where we fit in. In working with the spatial patterns of homeless people in Newark, Ohio, his interests are about designing urban communities to tolerate and encourage different peoples who perceive the environment differently.
Dr. Kaplan has two boys who love to explore and who care a great deal about the planet they're inheriting as they grow up. What can be more inspiring than that?

The threat of climate change has made supplying energy cleanly and sustainably one of the most important challenges facing humanity in the 21st century. This area of research is not only of critical importance, but also provides a framework for a host of fascinating fundamental scientific questions. My research is focused on finding new, low-cost designs and materials for solar energy conversion devices that can meet the growing global demand for energy. This work draws from many different disciplines of chemistry, including physical chemistry, analytical chemistry, materials chemistry, inorganic chemistry, as well as nanotechnology. In my research I use a wide range of instruments and experimental methods, such as photo-electrochemistry, spectroscopy, microscopy, and diffraction.
Specifically, I am interested in finding ways to use materials such as iron oxide (Fe2O3, a.k.a. rust) for solar energy collection and conversion. Iron oxide is a semiconductor that is abundant, stable and environmentally friendly but in particular its properties are optimal for absorption of sunlight. Another promising material is pyrite, FeS2, which is also cheap and abundant and absorbs light strongly. When used in conventional designs, both of these materials suffer from poor transport and collection of charge carriers, resulting in low overall conversion efficiencies. However, by growing crystals in novel nano-structured geometries, thereby separating the axes for light absorption and charge collection, we hope to overcome these limitations while keeping the material's cost low. Simultaneously, we will explore other approaches to improve the photoelectrochemical properties of these and other related materials with the use of dopants (incorporating a low concentration of another element into the crystal structure). In our research we hope not only to find promising new materials, but also expand our understanding of the fundamental principles that determine the photoelectrochemical and physical properties of semiconducting materials in general.

Dr. Kennedy joined the faculty at Denison in 1992 following completion of a four-year post-doctoral fellowship in behavioral immunology at Ohio State's College of Medicine. Dr. Kennedy teaches Physiological Psychology, Psychopharmacology, and Introductory Psychology, and is co-advisor to Denison's newly-formed Neuroscience Concentration.
My research interests are focused in two general areas of behavioral neuroscience and psychopharmacology. The first area is concerned with how animals' behavioral responses to stimulant drugs such as amphetamine might abe modified by previous drug experience. This work has implications for models of “addiction,” which maintain that early experiences (such as stress) may make an organism “at risk” for later stimulant addiction. Secondly, I am interested in the historical and cultural contributions to current drug policy, and the role of science versus popular culture in defining public policy regarding licit and illicit drugs.

I'm a volcanologist/petrologist and I teach classes on the rocks and minerals that make up the planet, along with the magmatic processes that lead to volcanic eruptions. I’ve been fascinated by geology since I was young, either with the vast mineral collection my grandmother in Massachusetts had collected or with the vistas of Nevado del Ruiz from my grandparents home in Colombia. Every rock (or crystal) does tell its own story, and that is what geologist do: unlock the history recorded in the rocks. That is how I like to teach geology – by looking at the process the created the rock and then how we see the record of that process imparted on the physical and chemical characteristics of the rocks and crystals. In that way, geology tells us about the dynamic events that have created the Earth and will change the planet far into the future. I am also interested in how humans interact with geology, specifically how we alter the su rface environment when exploiting the multitude of resources within the Earth. If you’re interested in any of these topics, contact me via email or on Twitter (@eruptionsblog).
My research focuses on volcanism and magmatism, both modern and ancient. I examine these processes by looking at the information recorded in crystals erupted in lavas and ash. By measuring the ratios of radioactive isotopes in these minerals, you can answer questions about the timescales of magmatic processes at volcanoes, such as how long does it take to generate a body of magma, how long can you store magma in the crust and what are the rates of eruptions during the lifetime of a volcano. All of these question lead us to a greater understanding of what happens under a volcano before an eruption.
Currently, I have active research projects at Lassen Peak in northern California, Mineral King in the central Sierra Nevada, and the Okataina Caldera in New Zealand. I have had students work with me on these research projects, leading to presentations at major geology meetings and co-authorships on research papers. If you’re interested in working with me, send me an email.
I also strong believe in making science accessible to the general public. To that end, I write a blog on volcanism called Eruptions. I distill the sometimes-disparate information out there about current eruptions, discuss volcanic process and features and break down current volcano research so that anyone can understand why its so exciting. The blog is visited by thousands of readers a day that vary from casual readers to seasoned volcano researchers.

Maia Kotrosits' research finds points of contact between ancient Christian/diaspora Jewish literature and contemporary cultural studies, queer and feminist theories. Surfacing themes of violence, belonging, and collective experiences of pain and loss, she finds connections and disjoints between the ancient world and some worlds of the present. She has co-written books on the ancient Coptic poem The Thunder: Perfect Mind, as well as on the Gospel of Mark. Her forthcoming book, Rethinking Early Christian Identity: Affect, Violence, and Belonging (Fortress Press, 2015) is a re-examination of the centrality of the designation "Christian" in the doing of what is called early Christian history, and a set of proposals for how to understand some New Testament and affiliated literature without it.

My research lies in the field of formal methods for software engineering. The focus is on the formal specification of software in the context of software engineering principles developed by experts in the field over decades of research and practice. Recent NSF funding has supported the design and development of a new language, RESOLVE (REusable SOftware Language with VErification), that includes constructs for formal mathematical specifications to promote mathematical reasoning and proofs of program correctness. Krone’s work has included both the development of logic for reasoning about program correctness and the development of material needed in the computer science curriculum to support mathematical reasoning about programs.

I think of myself as something of an intellectual vampire -- I feed off of the different aspects of my job. My research feeds my intellectual curiosity and helps keep my scientific knowledge current and well grounded in experience. Teaching is my passion, a real source of emotional energy. On this page, I've tried to give you an overview of both my teaching and research interests. I encourage you to look elsewhere on my web pages to find out more, and to email me or stop by to talk about anything here that intrigues you.
Broadly, my research interests lie in the area of Molecular Evolution. Specifically, I'm interested in the rates at which biological macromolecules evolve and the forces, both at the level of molecule and of organism, which constrain the rate of evolution of individual molecules.
The past decade has seen a true revolution in the technology of biomolecular sequence determination, and a corresponding explosion in the magnitude of sequence information available for analysis. This wealth of information has given us an increasingly clear picture of how and why biological macromolecules change over time. But it also highlights our ignorance. For example, virtually every large scale molecular evolutionary tree shows one or more groups of organisms with aberrant rates of evolution -- which shows up as unusually long or short branches. Yet no one is able to predict these rate hiccups, or even to explain them post-facto, and that intrigues me. But rather than simply looking for these cases of bizarre evolutionary rate, my interest is with the forces involved; I seek to explicitly test hypotheses about causal events that can drive rate abnormalities.
The goal of my research program is therefore to explore cases of altered evolutionary rate and to generate biochemical systems for testing hypotheses about the consequences of the rate acceleration. My focus for the last several years has been on one such case study: describing and exploring the accelerated evolution of the genes encoding the subunits of the RNA polymerase in chloroplasts of plants in the genus Pelargonium. To learn more about my research interests, and the projects that students have pursued in my lab, please see my research page.

Sangeet Kumar earned his PhD from the Department of Communication Studies at the University of Iowa where his dissertation studied the construction of postcolonial identities through the consumption and production of western popular culture in India. His current research interests are focused on two distinct but connected dimensions of the globalization of media and culture. The first interrogates power and resistance within global digital media networks from the perspective of postcoloniality, critical theories of technology and parody/satire. The second uses theories of human desire to reimagine power and identity within global popular cultural texts and practices. In addition to the Communication Department, he also serves on the International Studies committee at Denison. He has a background as a newspaper journalist with a daily in New Delhi prior to his academic career.
His research has appeared in journals including Popular Communication, Journal of Communication Inquiry, Global Media and Communication and Journal of South Asian History and Culture among others as well as in anthologies such as News Parody and Political Satire Across the Globe and Television at Large in South Asia among others.
At Denison his courses explore media, technology and popular culture from critical, theoretical and global perspectives. The courses he teaches are:
- Media and Modernity
- Global Digital Networks
- Cultural Globalization and Identity
- Democracy, Liberalism and the Mass Media
- Critical Cultural Approaches to Advertising
- The Politics of Popular Culture

My current research is on the political economy of Social Security reform. The Social Security Amendments of 1939 put the program on its modern trajectory. A pay-as-you-go approach to financing the program was firmly established and benefits were granted to spouses of retired workers and to dependents of deceased workers. These changes were made based on the recommendations of an Advisory Council on Social Security that was composed of members representing employers, employees, and the public. Two prominent economists of the period, Paul Douglas and Alvin Hansen, were among those members of the council chosen to represent the public.
I am currently involved in investigating their role in shaping the council's recommendations. I am particularly interested in how their views of the economic issues of the day shaped their analysis of the council's work.

I am a broadly-trained cultural anthropologist with primary research interests in semiotic anthropology, material culture and archeology, racial, ethnic, and linguistic identity. I have secondary interests in kinship, demography, anthropology and philosophy, and the history of anthropology. Most of my fieldwork has been conducted in Ireland, in Gaeltacht (Irish-speaking) communities. My recently completed projects include an analysis and critique of the logic of racial profiling, using C.S. Peirce's arguments about the various forms of logical inference including retroduction/abduction, and his theories about iconicity. My current research can be described broadly as the semiotics of material culture. I am engaged in an ongoing project investigating the phenomenological, temporal, and semiotic manifestations of material objects from the past in the present, focusing specifically on archaeological artefacts. Related to this I have recently begun a new project on the semiotic aspects of ‘vintage fashion’. I teach courses on semiotic anthropology, social theory (classical and contemporary), race and ethnicity, as well as courses in International Studies. I also teach our introductory course as well as our senior seminar.
