Castleton students have a couple different avenues available for pursuing scientific research with faculty.
The Castleton Faculty-Student Research Committee sponsors grants each semester for undergraduate student research. The research project must include at least one undergraduate student and at least one faculty mentor. A research proposal summarizing the background, nature, rationale, and significance of the proposed study must be written, with deadlines in October and March.
Castleton Summer Science Research internships are also available each spring to students that approach a science faculty member and prepare a written proposal for their work.
Lastly, externally funded research projects may be available through grants awarded to our faculty. Over the last 6 years science faculty have been awarded over $750,000 in these grants, which have funded many students for summer work. If you are a student interested in doing undergraduate research in the sciences, please contact faculty directly to find out more information about current research opportunities, including independent studies and summer research.
Dr. Justin Carlstrom’s research interests include investigations on the effect of various substances on anaerobic and aerobic performance. He is currently looking at the effect of both caffeine and sodium bicarbonate on indicators of performance in collegiate rugby players. This work is being completed on campus with the help of students majoring in Exercise Science. They are utilizing state-of-the-art equipment including a Parvo Medics Metabolic System and the Velotron electronically-braked cycling ergometer. In addition, they will soon be examining the effect of various protocols and nutritional strategies on recovery from strenuous exercise.
Dr. Brad Coupe is an animal behavior biologist particularly interested in the evolution of traits used in competition for access to mates or as a result of mate choice by the opposite gender. The evolutionary process leading to these traits is a subset of natural selection called sexual selection. The effects of sexual selection are most easily observed in the form of weapons, such as antlers, and bright coloration, as seen in many bird species. Currently, students in his laboratory are studying the potential for red coloration to serve as a signal of mate quality in long-nosed dace, a fish common in local streams. Additionally, Dr. Coupe is involved in a collaboration with Dr. Meriel Brooks of Green Mountain College studying the ecology of larval fish. The focus of this work is on a phenomenon called "larval drift" in which fish larvae can be found drifting down stream. A number of students from both institutions are involved in this project.
Dr. Preston Garcia's research will focus on the work he did at UConn, specifically looking at genetic regulation of Sinorhizobium meliloti. Dr. Garcia's lab is looking to further characterize genes associated with metabolic regulation and control of succinate-mediated catabolite repression (SMCR) in Sinorhizobium meliloti through the two-component regulatory system,sma0113/sma0114. S. meliloti utilizes C4-dicarboxylic acids as preferred carbon sources for growth while suppressing the utilization of alternative carbon sources such as α- and β-galactosides. Sma0113 has been identified as a member of a two component regulatory system which relieves SMCR in cells grown in succinate with either lactose, maltose or raffinose. The two component system is comprised of the histidine kinase, Sma0113 and the cognate response regulator, Sma0114. Contained within Sma0113, PAS domains are known to sense energy state and redox levels inside cells. He hypothesizes that this two component system may use sensory information about redox levels or energy state gathered from the PAS domains to modulate electron flow, metabolism and catabolite repression. The current goal of the lab is to elucidate the function of the system through chemotaxis studies, whole cell biosensor expression with the plant host and solidifying the role that phylogenetically related genes have in regulating the external sensing through sma0113/sma0114.
Dr. Tim Grover's primary research interests are in the fields of metamorphic petrology, structural geology and tectonics. He likes to study the physical and chemical processes, such as recrystallization, ductile deformation, mylonitization, and migmatization that occur in the crust during mountain building. His research is field-based and often begins with bedrock mapping. Bedrock mapping enables a geologist to determine the different rock types in an area, examine the contact relationships between various rock units, and to characterize the structural features of an area. Bedrock mapping really provides a foundation for further research. Dr. Grover's research involves examining rocks on a variety of scales, from map scale, to outcrop scale, to hand sample scale, and thin section scale. The metamorphic minerals in a rock can be used to constrain the temperature and pressure conditions during metamorphism. The textural relationships between the minerals can yield data regarding the relative timing of metamorphism and deformation and yield information regarding the nature and extent of the deformation. Data collected from the various scales of observation are then integrated and compare to existing data to develop constraints on models for the geologic evolution of a given area.
Dr. Grover's current field area is the eastern Adirondacks in upstate New York. During the summer of 2010, he had three senior students doing bedrock mapping with three additional underclassmen acting as field assistants. The three senior students are currently working on their senior thesis. Their research topics are: examining the relationship between a sequence of paragneisses and associated granitic gneisses to see if the granitic rocks might have formed from partial melting of the paragneisses; examining kinematic indicators in a ferrogabbro-anorthosite suite to determine it’s deformational history; and the petrogenesis of leucogranitc rock unit and it’s relationship to a possible intrusion breccia.
Dr. Helen Mango is currently researching the occurrence of arsenic in groundwater in southwestern Vermont. This research has grown out of her interest in the geochemistry of aqueous solutions and how metals are transported by these solutions. The Slate Belt of southwestern Vermont contains rocks that sometimes include pyrite (“fool’s gold”), and this pyrite often contains elevated concentrations of arsenic as a naturally-occurring element substituting for sulfur in the pyrite structure. Castleton students have been involved in this research, helping collect water and rock samples for arsenic analysis, and measuring rock fractures to determine groundwater flow direction.
Dr. Cynthia Moulton conducts ecological field research with students to study plethodontid salamanders in Vermont stream sites using mark/recapture
techniques to assess population dynamics, distribution and movement. These lungless salamanders are an important link in the food web that connects aquatic and terrestrial habitats and can be an indicator of ecological integrity. In the future she hopes to work with students to study the genetics of variation in morphology of newly discovered potential hybrids.
Dr. Christine Palmer is interested in how plants respond to the environment, from the molecular to physiological to ecological level. This work includes investigating how plants deal with metals in the environment with the goal of increasing human nutrition and cleaning up toxic metals from soils. Dr. Palmer has also investigated how plants respond to shaded environments to help us increase agricultural productivity. At Castleton, she hopes to work with students to continue studying these questions as well as to start new research on invasive species that are plaguing the local ecosystems of Vermont.
Timothy Thibodeau is excited to join the Natural Sciences faculty in the fall of 2014. He has always been interested in studying both Chemistry and Physics. He received his Bachelor’s degree in Chemistry from Saint Anselm College. As an undergraduate, he studied the surface chemistry of a high temperature superconductor using infrared spectroscopy. Then, he went to the University of Maine to earn his doctorate in Physical Chemistry. While at the University of Maine, he was part of a renewable fuels research group. He utilized theoretical and experimental methods to determine ways of increasing the energy content of this fuel.
Dr. Livia Vastag is interested in metabolism and the regulation of material flow in cells. Her most recent research projects included characterization of metabolic events during early embryonic development of frogs, and investigating how Herpes viruses acquire cellular materials to replicate themselves. At Castleton, she hopes to engage students in research aimed at understanding and optimizing the ways that bacteria, such as Clostridium acetobutylicum, produce fuels which can be substituted for gasoline.
Dr. Andrew Vermilyea studies naturally occurring reactions in lakes and streams that, with the help of the sun, can destroy organic based contaminants such as BPA that is leached from many consumer plastics. He is also interested nutrient export from various watersheds since they are important in maintaining a healthy ecosystem. He works in glacial watersheds and studies their role in supplying important nutrients (carbon and nitrogen) to the sea life in the Gulf of Alaska. Additionally, he is partnered with UVM to research phosphorus and carbon nutrient export into Lake Champlain.
If you are an undergraduate student interested in traveling to another location for a summer research experience, there are many opportunities available to you. The National Science Foundation (NSF) funds the Research Experiences for Undergraduates (REU) program at many different sites across the country. REU projects involve undergraduate students in meaningful ways in ongoing research programs at departmental or multidisciplinary levels. Other opportunities include: Vermont EPSCoR (Experimental Program to Stimulate Competitive Research) and Vermont EPSCoR (NEWRnet).
