Lauren Hammond
Visiting Assistant Professor,
Consortium for Faculty Diversity Post-Doc Fellow
Latin America
Faculty  |  History
Fellows Hall
B.A., University of Virginia; M.A., Ph.D., University of Texas at Austin

Dr. Lauren Hammond is a historian of the African Diaspora in Latin America and the United States, with a focus on the Dominican Republic. Her research interests include racial identity formation, diasporic practice, U.S. empire, dictatorship, the island of Hispaniola, and African-American—Dominican relations. She offers survey courses on colonial and modern Latin America and upper level courses on the African Diaspora.

Her current research project examines African-American interventions in U.S.-Dominican relations from Reconstruction to the height of the Civil Rights Movement. The work shows how African-American elites, moved by the African ancestry they shared with Dominicans, sought to use their limited influence in U.S. foreign policy circles to attempt to shape U.S. policy in the Dominican Republic. In doing so, the project also highlights the limits of Afro-diasporic politics, particularly between African-descended groups who identify as black and those whose histories preclude them from doing the same.

Dr. Hammond is from Richmond, VA. She received her B.A. in History and African and African-American Studies from the University of Virginia and her M.A. and Ph.D. in Latin American History from the University of Texas at Austin. Prior to coming to Denison, she taught at Southwestern University in Georgetown, TX.

B.M., M.M., D.M.A., Ohio State University

Pianist Nelson Harper is known for his versatility as both soloist and chamber musician. He has appeared in several summer music festivals, including the prestigious Grand Teton Music Festival, and for many years has been heard in both solo and chamber music performances at least twice yearly in live broadcasts on Chicago's Fine Arts Radio Station, WFMT.  Among artists with whom he has performed in addition to his thirty-four year duo with violinist Michael Davis are the Chicago Symphony's principal flutist Donald Peck, trumpeter James Thompson, violinists MaxRostal and Yfrah Neaman, soprano Lucy Shelton, clarinetist Luis Rossi and numerous other singers and instrumentalists. 

Nelson Harper made his London debut in December of 1989 at the Wigmore Hall in a program of British duo sonatas of the 20th century with violinist Michael Davis. That recital included the world premiere of the Third Sonata for violin and piano  by Wilfred Josephs, dedicated to the two artists. The critic of the London Guardian wrote of that recital “both players are individually most sensitive and accomplished, while as a duo they seem to play with a single mind.” When they repeated the program live over WFMT in Chicago, Robert Marsh of the Chicago Sun-Times called it “one of the most attractive recitals of the season” and praised the duo as “two superior, well-matched musicians who perform the violin and piano repertoire with sensitive, imaginative interaction.”

Dr. Harper is featured on seven compact discs on the Vienna Modern Masters, Koch International, Orion, and d'Note labels.  A recording of solo piano and chamber works by Welsh composer William Mathias, done at the request of Oxford University Press, was released on the Koch International label in the summer of 1996, with the American Record Guide review singling out “especially the elegant playing of pianist Nelson Harper.”

Nelson Harper’s principal teachers were Paul Strouse, Richard Tetley-Kardos, and Earl Wild. Dr. Harper was a recipient of The Ohio State University School of Music’s Distinguished Teaching Award while on the faculty there, and is currently Coordinator of Keyboard Studies at Denison University.

Dr. Hassebrock came to Denison in 1983 and teaches courses in Cognitive Psychology, Adult Development and Aging, Research Methods in Psychology, and Introduction to Psychology and seminars on The Seven Sins of Memory: The Psychology of Remembering and Forgetting, and Autobiographical Memory and the Remembering Self.

In 2011, Dr. Hassebrock was named as a Teagle Pedagogy Fellow by the Great Lakes College Association. Teagle Pedagogy Fellow have key roles in the development of a new consortial program, called the GLCA Lattice for Pedagogical Research and Practice, created with funding from the Teagle Foundation. These Fellows engage with interested faculty members on their own campuses and at other GLCA colleges, helping to generate heightened interest and momentum in exploring different modes of pedagogy to enhance student learning and achievement.

At Denison’s Honors Convocation in April 2013, Dr. Hassebrock received the Charles and Nancy Brickman Distinguished Service Chair, 2013-2016.

Dr. Hassebrock was selected in 2013 to be Denison’s first Faculty Fellow for Learning and Teaching. In this role, he collaborates with Denison’s faculty members, at all career stages, on teaching-related issues in order to:

(a) provide individual support and consultation,
(b) develop opportunities and provide information for the exploration of innovative pedagogies and new initiatives,
(c) promote access to scholarship and research on learning and teaching,
(d) coordinate relevant activities, programs, and resources across campus, and
(e) support a shared culture of discussion, reflection, and experimentation about learning and teaching activities.

Research Overview: 
Cognitive psychology; episodic and autobiographical memory; age and gender differences in remembering experiences and life events; identity and life narratives associated with keepsakes and mementos; Scholarship of Teaching and Learning (SoTL).
Research Details: 

My recent research projects have explored the cognitive psychology of autobiographical memory including age and gender differences in remembering meaningful personal experiences and significant life events. Another direction of this research has compared the different types of memory functions (e.g., self, social, emotional, and motivational) that guide how adults of different ages recall autobiographical memories associated with consumer objects versus keepsake objects including mementos and souvenirs.

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.

Research Overview: 
Evolution and classification of the Adder’s Tongue fern family, focusing on the population-species boundary.
Research Details: 

Molecular Systematics of the Ophioglossaceae (Adder's Tongue Fern Family)

  • Phylogeny of Ophioglossaceae based on morphological and molecular data
  • Phylogenetic relationships in Botrychium s.s., the moonworts
  • ISSR variation within and among North American species of Sceptridium, the grapeferns, using ISSR markers and DNA sequences
  • Phylogenetic relationships among species of Ophioglossum s.s., the adder's tongue ferns
  • ISSR variation within Florida populations of Cheiroglossa palmata, the hand fern
  • ISSR variation within and between Australian and Hawaiian populations of Ophioglossum (Ophioderma) pendulum, the ribbon fern
  • ISSR variation within populations of Helmithostachys zeylanica

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.

Research Keywords: 
Algorithms, computational biology
Research Overview: 
I enjoy designing efficient online algorithms for network and scheduling problems. Like a market speculator, an online algorithm must respond to input as it arrives, without knowing the future. I am also interested in computational biology problems.
Research Details: 

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.

B.S., University of Maryland; M.S., University of Bridgeport; Ph.D., Pennsylvania State University

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.

Research Details: 

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.

Research Focus

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.

Research Overview:

Research Details: 

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.

Research Details: 

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.

Gender Differences

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 .
