Bachelor of Science Degree • School of Arts and Sciences
The biology faculty of Utica College is noted not only for the quality of its teaching but also for the depth and breadth of its scholarship. Research conducted by faculty members involves students. These students earn research credit, gain valuable field and lab experience, and publish their research in peer-reviewed scientific journals. This student research has been supported by grants from the National Institutes of Health, the National Science Foundation, NASA, the National Geographic Society, The Alden Trust, The Community Foundation, and the New York Energy and Development Authority. Many biology professors have been honored with the college's awards for distinguished teaching, research, or both.

Brief Autobiograhical Statement
I grew up in Binghamton, New York and received my B.S. in Biology at Binghamton University (formerly SUNY Binghamton) in 1993. I then enrolled in the East/West Marine Biology Program, which is a 1-year non-degree program run through Northeastern University. I earned my M.S. in Ecology & Evolutionary Biology / General Biology from the University of West Florida in 1997. My project examined the predator-avoidance behaviors of an aquatic snail. When I finished there, I enrolled at the University of Kentucky and received my Ph.D. in Biology in 2003. I continued working with the snails during my dissertation project, focusing on factors that influence the mating system. I then moved north of the border to accept a Postdoctoral Fellowship position at the University of Lethbridge, which is located in Alberta, Canada. While the research still focused on mating systems, the study organism was very different; we examined mating behaviors and phonotaxis (movement in response to acoustic signals) in field crickets. I also had the opportunity to work as a Sessional Lecturer teaching an introductory course: Diversity of Life.
Research Interests and Research in Progress
My interests are both behavioral and ecological in nature. Most of my work has examined how organisms avoid being killed by predators, how organisms find and assess potential mates, and the trade-offs associated with balancing these activities. I am also interested in how changes in the context in which interactions occur alter behavioral dynamics during, and the outcomes of, those interactions. I have addressed these questions using invertebrate systems: my Ph.D. dissertation examined the mating strategies of a species of aquatic snail. In order to determine whether the genetic similarity of mates influences mating systems, I compared the behavioral dynamics and reproductive success resulting from controlled matings between individuals of known relatedness (e.g. siblings or cousins). Additionally, I examined whether changes in the context in which the interactions occur (e.g. levels of predation risk) influenced mating behaviors. The fact that the snails are hermaphrodites (simultaneously possess both male and female reproductive organs) makes these questions much more interesting and complex. Other studies have addressed a variety of topics, including: the effects of temporal patterns of predation risk on prey behavior (snails), examining the simultaneous effects of injury-released chemical cues on the behaviors of prey and their predators (snails & crayfish), comparing male calling durations to male phonotactic responses (crickets). I am also interested in how parasitism affects mating strategies (crickets and/or snails).

Opportunity for Student Research
The invertebrate animals that I study are relatively easy to work with and would provide numerous opportunities for undergraduate research projects. I would encourage highly motivated students interested in gaining research experience to either conduct their own research under my supervision, or to participate in one of my projects. Some of my research goals include:
* Examining some of the 'gender' implications for hermaphrodites with regards to: a) the physiological mechanisms involved in switching genders; b) individuals' behavioral tendencies to occupy each gender role; and c) asymmetrical gender-based mating preferences
* Studying the effects of 'inbreeding depression' on: a) locomotion rates; b) growth rates; c) type and efficacy of predator-avoidance behaviors; and d) tolerance to environmental stressors (e.g. temperature fluctuations). Many studies have examined the effects of inbreeding on reproductive success and viability of offspring, but fewer studies have examined the effects of inbreeding that may be expressed later in life.
* Assessing the effects varying temporal patterns of predation risk on mating behaviors. Some recent theory predicts that prey organisms exposed to similar conditions will behave differently (with regards to time spent foraging) depending on how often they have experienced predation risk in the past. I am interested in determining whether this theory can be extended to mating behaviors.
* Examine the foraging strategies of individual crayfish. Crayfish consume snails using several techniques (e.g. chip away shell aperture, snap off shell spire, crush entire shell, pull animal from intact shell), and previous observations have suggested that individual crayfish have one or two favored strategies. I am interested in determining whether foraging strategies differ among individuals and what factors will influence these behaviors (e.g. crayfish size, snail size, etc.).
* And many more?
