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?

Field of Interest:
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.

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 Langauage 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.

Field of Interest:
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.
