Barker, Joel
Assistant Professor of Earth Sciences

Biogeochemical investigations examine the diverse interactions between biological and geological ecosystem components.  My research program focuses on understanding biogeochemical processes in Earth’s alpine and polar environments.  High altitude and latitude environments are unique because they spend prolonged periods under cold or frozen conditions, which affects both biogeochemical processes and the generation of biogeochemical products in novel and poorly understood ways.  Cold regions are experiencing amplified rates of warming as global climate changes, and the biogeochemical response to this change is unknown and important as sources of carbon and other nutrients, previously sequestered in frozen environments, are made available by a warming climate.  Current research activities examine how these sensitive ecosystems respond to physical, climatic, and hydrologic changes on time scales ranging from days to millions of years.  Please visit my web page for a more detailed description of my research program and specific projects that are underway.

Bobbitt-Zeher, Donna
Assistant Professor of Sociology

My research agenda primarily concerns gender and inequality, how gender inequality changes over time, and the consequences of these changes.  I use both quantitative and qualitative methods in my work, and draw on a race/class/gender perspective as well.   My scholarship focuses on three veins of gender inequality:  educational inequalities and labor market outcomes, workplace discrimination, and intimate partner violence.  Research in the first vein examines how broader social changes, particularly changes in women’s education, but also workforce participation, and family life, effect the gender income gap in the late 20th century.  My second area of research interest concerns workplace discrimination, especially processes of gender discrimination and pregnancy-related discrimination.  My third area of research focus concerns intimate partner violence.  During the last decades of the 20th century, reflecting broader societal changes in attitude, states and localities altered laws to address intimate partner violence.  Ongoing research in this vein considers the consequences of these changes.

While the majority of my research has focused on these topics, my interests in societal change and its implications extend beyond issues of gender.  For example, some of my work examines contemporary issues related to changes in families, such as caregiving for loved ones with Alzheimer’s disease and the implications of number of siblings for adolescents’ social skills.

Braun, Catherine

Associate Professor of English

Research Interests:  Digital Media Studies; Literacy Studies, including Digital/Electronic/Media Literacies; Computer-Mediated Communication and Pedagogy; Composition History, Theory, and Practice; Rhetorical History, Theory, and Practice, including Visual Rhetoric and Rhetoric of Technology



Crosby, Sara

Assistant Professor of English

Daddis, Chris
Associate Professor of Psychology

Dr. Daddis’ research employs a social cognitive approach in studying the development of adolescent autonomy that focuses on changes in adolescents’ and parents’ reasoning about the boundaries defining adolescent and parent authority.   Two related lines of research examine the process. The first explores the influence of peers on adolescents’ construction autonomy beliefs and the second examines differences in the ways that adolescents actively assert autonomy through active management of information about their lives.

Gershman, Susan
Assistant Professor of Evolution, Ecology and Organismal Biology

I study the evolution of animal behavior. I am most interested in the coevolutionary arms race between males and females over conflicting optimal fitness strategies.

I primarily use crickets and Drosophila flies as my study systems, but I have also worked with other insects and salamanders. Some of the research questions that I address include: What behavioral and morphological adaptations do males use to outcompete other males for reproductive success? How do adaptations that help males outcompete other males affect females? When male traits that are attractive to females are complex, how can selection act on these traits and on female preference for male traits? To address these questions, my research draws on techniques from behavioral ecology, life history evolution, quantitative genetics, immunology, and analytical chemistry. My current research directions include: (1) Sexual conflict over courtship feeding gifts in Gryllodes sigillatus decorated crickets, (2) Adaptive plasticity in sexually selected cuticular hydrocarbons in male Drosophila serrata flies, (3) The immunological costs of mating for male and female crickets and beetles, (4) The benefits of female choice for novel partners, and (5) Sexual conflict over the optimal number of times for females to mate. I am also interested in starting new research on: (1) Adaptive plasticity in Gryllodes sigillatus spermatophylax composition, and (2) Variation in wing interference patterns in flies.

Klips, Robert

Associate Professor of Evolution, Ecology and Organismal Biology

My areas of interest are flowering plant reproductive ecology and prairie restoration ecology.  Flowering plant breeding systems, bryophyte ecology. Current foci are: (1) assessing the effects of population structure and pollinator visitations rates on self and outcross pollination in prairie milkweeds, (2) assessing the importance and prevalence of bryophytes in the early establishment of restored wet prairies.  Overall research goals are to better understand the forces influencing plant distribution and plant evolution, and to accomplish environmental enhancement through more effective grassland restoration.

Areas of Expertise: flowering plant reproductive ecology, prairie restoration ecology, forest bryophyte ecology

Klochko, Marianna
Associate Professor of Sociology

I was always interested in the general philosophical question of’ how the society works’.  Being born and raised in the former Soviet Union (specifically Ukraine) made me ask questions about the experiences of transitional societies ... the reasons why transitions are made and their consequences for individuals in the various strata of society.  This puzzle led me to study corruption and the possibility that a disruptive transition such as the one experienced by the successor states of the USSR might lead society from one imperfect equilibrium to another.  In the process of trying to understand corruption I realized that other social phenomena are influenced by a similar factor; namely, the discount people place on future outcomes as compared to more temporally immediate things.  This has led me to focus on the relationship between individual time preferences and social phenomena such as drug addiction, gang membership and prisoner recidivism.   What might drug addicts, criminally inclined youth, and prisoners have in common and what are the psychological parameters that participation in AA programs and prison rehabilitation programs are intended to impact?  I address questions of this sort from the assumption that people's  time preferences are not constant and are subject to change due to the exposure to a new culture, life changing events and interaction with others in the new social settings.  More work needs to be done do determine the role of different social factors and the way they interact and affect the change in individual time preferences.  Of course, my origins still have a profound impact on my interests and perspectives and thus my other project is a study of electoral fraud in Ukraine. 

Lang, Jan
Professor of Mathematics

The main field of my research is in Analysis and I focused, among others, on the following areas:

(i) Approximation theory and s-numbers:
The s-numbers, which were introduced by Pietch in 1974, are an important tool for studying properties of operators on Banach spaces. Approximation, Kolmogorov, Bernstein, Mityagin and Gel'fand numbers are s-numbers which are widely used in approximation theory and operator theory to describe how well a given compact map can be approximated. In a series of papers with my collaborators, we were able to obtain exact first and second asymptotic terms for some integral operators and exact values of s-numbers for Sobolev embeddings and Hardy type operators. These results are contained in my recent book and are based of my study in this field.

(ii) Eigenvalues for non-linear systems and Special trigonometric Functions:
Recently was shown that p-Laplacin and Non-linear System of Differential equations can lead to a system of eigenfunctions which are related to Generalized Trigonometric functions (i.e. more general version of classical trigonometric functions). These Generalized Trigonometric functions are extremely important in exact estimates in Approximation Theory and study of their structure is essential for Approximation Theory.

Lishan, Stuart
Associate Professor of English

Maharry, John
Associate Professor of Mathematics

Dr. Maharry’s research is broadly focused on describing structures within graphs or networks and exploiting those structures to answer questions about the overall network. In his research, graphs or networks are systems of nodes with links (or edges) connecting them.  Examples are all around including computer networks, electrical circuits, social networks, organizational networks, chemical reactions and molecular structures.  Abstract network models can also be applied to solve scheduling, matching,  epidemiology and diffusion problems.

In particular, Dr. Maharry’s research deals with graph decompositions, tree-structures, surface embeddings and minor- and topological-inclusions of graphs. His current project is to show that short-chained, bounded tree-width graphs are well-quasi-ordered under topological inclusion.

McCorkle, Ben
Associate Professor of English

Dr. McCorkle studies various historical periods when established and emerging communication technologies collided with one another. His work explains how society made sense of these moments of technological transition, the arguments that people made in order to adjust to new communication practices, forms, and rules. He is also interested in our contemporary digital landscape, as well as the factors that help shape it: the cultural, the historical, the political, the technological, and the rhetorical. He is the author of the book Rhetorical Delivery as Technological Discourse: A Cross-Historical Study, published by Southern Illinois University Press. He has also published essays in various journals and edited collections, including Computers and Composition Online, Rhetoric Society Quarterly, and Composition Studies.

Parsons, Linda

Associate Professor of Education

Research Interests:  Middle Childhood Literacy; Children's/Young Adult Literature; Reader Response

Her research interests include the content analysis of children's and young adult literature, both single titles and sets of books, to better understand the messages conveyed to young readers. She has also explored and documented children's engagement with and response to literature. The unique challenges involved in reading and responding to multimodal texts are also an area of interest. Her research and teaching pedagogy are situated primarily within the traditions of reader response, feminist, poststructural, and social-constructivist theories.

Patson-Huffman, Nikole
Assistant Professor of Psychology

My research focuses on adult language comprehension. The act of comprehending a sentence usually feels effortless and simple. However, it is not uncommon for comprehenders to make mistakes they aren’t aware of. One common cause of this kind of mistake is that comprehenders sometimes leave words or even syntactic structures underspecified (e.g., Patson, Darowski, Moon, & Ferreira, 2009). For example, someone who read “this work fills an important gap in the literature” as indicating that the work is important, would have committed this kind of error. This interpretation follows from a shallow reading that combines the related and expected concepts of importance, work, and filling gaps, but fails to specify the crucial relationship between “important” and “gap”. I am interested in what factors contribute to when and how often sentence comprehenders leave information underspecified, leading to these kinds of errors.

My research has focused on the conceptual representation of plurals. For example, consider the sentence The cats slept on the rug. When a comprehender hears this sentence what conceptual representation is built for “cats”? The plural referent cats could be left underspecified and represented as a single, non-differentiated group or it could be fully specified and thus represented as a set of differentiated cats. This question is important because if plurals are left underspecified, this could have implications for future processing. For example, if later the individuals in the plural need to be accessed, comprehension may slow down in order to individuate the entities in the plural, if it had not been previously done.

Tylka, Tracy
Associate Professor of Psychology

Within the field of counseling psychology, Dr. Tylka holds particular interest in body image and eating behavior. She conceptualizes both body image and eating behavior along a spectrum from positive (adaptive) to negative (maladaptive) and studies women and men along this spectrum. She examines sociocultural, psychological, and relational correlates of eating behavior. Recently, she has articulated great interest in intuitive eating, an adaptive style of eating characterized by attending to physiological hunger/satiety cues rather than emotional and/or situational cues. She has developed and psychometrically evaluated many instruments including the Intuitive Eating Scale, the Body Appreciation Scale, and the Male Body Attitudes Scale. She is an ad-hoc reviewer for the Journal of Counseling Psychology, Sex Roles, and Basic and Applied Social Psychology.

Wallace, Nathan

Assistant Professor of English

Willow, Anna
Assistant Professor of Anthropology

Dr. Willow’s main research interests include environmental anthropology, environmental justice, landscape, ethnohistory, Native North American studies, Anishinaabe/Ojibwe language and culture, and environmental education and behavior.  She has investigated and written extensively about the cultural and political dimensions of Anishinaabe anti-clearcutting activism in northwestern Ontario, Canada.  In addition, Dr. Willow has worked with Anishinaabe communities in northern Wisconsin to document the historical and contemporary importance of wild rice and other culturally significant natural resources.  More recently, she analyzed indigenous individuals’ and tribes’ responses to an invasive beetle called the emerald ash borer (EAB), which has the potential to devastate populations of black ash (an important basketry material throughout northeastern North America).  Dr. Willow recently received a grant from the Wenner-Gren Foundation for Anthropological Research to explore the cultural and political dimensions of indigenous participation in boreal forest conservation initiatives.  She is also developing a local ethnographic project that will consider the sociocultural contexts and consequences of unconventional natural gas development (also known as hydraulic fracturing or simply “fracking”) in Ohio.

Yoder, Ryan
Assistant Professor of Chemistry

Dr. Yoder's current research involves the use of molecular modeling experiments to solve critical issues that threaten the health of populations around the globe.  Specifically, combatting the effects of toxic organophosphorus nerve agents, such as the sarin gas used in the 2013 attack in Syria, and the detection of harmful anions in aqueous solutions where abnormally high levels exist naturally in areas of the developing world.  Current efforts involve molecular docking studies examining the interaction of potential therapeutics with acetylcholinesterase (AChE) and modeling of the spectroscopic principles of potential aqueous fluoride, chloride, and bromide probes.  These projects are a part of larger collaborations with faculty in Columbus and provide an opportunity for students who may be seeking a variety of career paths to participate in undergraduate research on campus in Marion .  Students involved in these projects have presented their work at the Denman Undergraduate Research Forum and the National Meeting of the American Chemical Society among other proceedings.
