Research Assistant (1994-1995) for E. Moran, Department of Anthropology, Anthropological Center for Global and Environmental Change, Indiana University, Bloomington, Indiana. Examined the relationship between vegetation regrowth and previous land use, soil fertility, and fallow age in Brazilian Amazon.
Courses Taught at Susquehanna University
Core perspectives: Biology Department Freshman Seminar (Fall 2005) Introduces incoming students to the university and the issues faced during the transition from high school to the university in order to improve success in college. The Fall 2005 seminar focuses on the alcohol. Topics covered include fermentation biology, neuroscience of addiction, and issues related to drinking on college campuses. [Developed seminar along with Dr. Tom Peeler, Dr. Dave Richard, and Dr. Jan Reichard-Brown]
Ecology, Evolution, and Heredity (Fall 2003, 2004 & 2005) Introductory course for majors; explores the nature of scientific investigation and the impact of human activity on the biological world by examining such topics as ecology, evolution, and genetics. [Coauthored Ecology, Evolution, and Heredity Lab Manual with Dr. Matt Persons]
Ecology (Fall 2005) Upper-level majors course; explores the complex ways in which living organisms interact with one another as well as their physical environment and encourages critical thinking through readings and discussions of the primary ecological literature. [Redesigned course and associated lab]
Issues in Biology-Topic: Economic and cultural botany (Fall & Spring 2005) Non-majors science course; introduces students to the diverse ways in which humans interact with plants, covering topics such as the origins of agriculture, the manipulation of plants by people, plants as a source of spices, medicines and psychoactive drugs, and the genetic engineering of plants by people. [Developed new course and associated lab]
Plant Ecology (Fall 2003) Upper-level majors course; explores the ways in which biotic and abiotic factors affect the abundance and distribution of plants in natural communities. Surveys the various sub-disciplines within the field (e.g. physiological ecology, population biology, community and ecosystem ecology). [Developed new course and associated lab]
Plant Physiology (Spring 2004 &2005) Upper-level majors course; explores the fundamental principals of plant physiology (transpiration, photosynthesis, translocation, nutrient uptake), with an emphasis on how these physiological processes are affected by abiotic and biotic environmental factors. [Restructured course and associated lab]
Systematics (Spring 2004) Sophomore majors course; surveys the kingdoms of life (the prokaryotes, eukaryotic protists, fungi, animals and plants). Exposes students to the diversity of organisms so that they can explore concepts of phylogeny, taxonomy and evolution.
Biology Seminar (rotates) The capstone course for senior biology majors; students conduct a year long research project under the supervision of a faculty mentor. Students also attend regular talks given by invited external speakers. [Developed evaluation forms for students to complete in order to improve their ability to critically evaluate speakers]
Mentored senior research projects: Ashley Shade ’04, Ryan Bell ’04, Mike V. Cole ’04, Erica Walker ’05, Katie Richter ’05, Magali Laitem ’05.
