Salt marshes, lakes, streams, Isle Royal, the interior lakes on Newfoundland, North Atlantic, North Pacific and Arctic Oceans, I am interested in anything that lives in water.

In my lab we have done projects with various fish, macroalgae, freshwater plants, aquatic carnivorous plants, invertebrates, E. coli and moose. We developed a biological control for Eurasian watermilfoil. In this project Middlebury students worked out the life history of a native insect that has switched to instead eat the invasive plant.

A second extensive project is measuring the effects of “bottom up” control by addition of nitrogen and phosphorous to salt marshes creeks and “top down” control by removing the top carnivorous fish in the creeks in New England as part of project TIDE (http://www.mbl.edu/tide/). We are constantly amazed at the results, for example, we have not seen much effect on system algae, but the walls of the creeks are collapsing so it is hard to count.

After retraining in molecular biology, we are now looking at the population genetics of lamprey in Lake Champlain, and straightening out the taxonomy of the aquatic plant genus Najas. Questions include: Are some species of Najas rare and threatened and should be protected? Or are they invasive and need to be controlled?

Funding has come from the National Science Foundation, U. S. Fish and Wildlife Service, EPA, U.S. Army Corps of Engineers, USGS, and appreciated in house funding from Middlebury College.

BIOL 0211 - Biostatistics      

Experimental Design and Statistical Analysis
Experimental design is one of the most important parts of doing science, but it is difficult to do well. How do you randomize mice? How many replicate petri plates should be inoculated? If I am measuring temperature in a forest, where do I put the thermometer? In this course students will design experiments across the sub-areas of biology. We will run student designed experiments, and then learn ways to analyze the data, and communicate the results. Students planning to do independent research are encouraged to take this course. (BIOL 0140 or BIOL 0145). DED

BIOL 0304 - Aquatic Ecology      

Aquatic Ecology
In this course we will combine field-based laboratory exercises with classroom activities to examine how humans interact with aquatic ecosystems and how these systems contribute to our understanding of fundamental ecological concepts. Our field trips will focus on aquatic ecosystems and organisms in Vermont, but we will also consider aquatic ecology more broadly through several modules linking processes across ecological scales from whole ecosystems to individual organisms. Evaluation will be based on periodic quizzes, reports synthesizing the laboratory modules, exams emphasizing the concepts covered, and an independent research project. (BIOL 0140). 3 hrs. lect./3 hrs. lab. SCI

BIOL 0500 - Independent Study      

Independent Study
In this course students complete individual projects involving laboratory and/or field research or extensive library study on a topic chosen by the student and a faculty advisor. Prior to registering for BIOL 0500, a student must have discussed and agreed upon a project topic with a member of the Biology Department faculty. Additional requirements include attendance at all Biology Department seminars and participation in any scheduled meetings with disciplinary sub-groups and lab groups. This course is not open to seniors; seniors should enroll in BIOL 0700, Senior Independent Study. (BIOL 0211. Approval required) 3 hrs. disc.

BIOL 0701 - Senior Thesis      

Senior Thesis
Seniors majoring in Biology who have completed one or more semesters of BIOL 0500 or BIOL 0700 and who plan to complete a thesis should register for BIOL 0701. In this course students will produce a written thesis, deliver a public presentation of the research on which it is based, and present an oral defense of the thesis before a committee of at least three faculty members. Additional requirements include attendance at all Biology Department seminars and participation in any scheduled meetings with disciplinary sub-groups and lab groups. Open to Biology and joint Biology/Environmental Studies majors. (BIOL 0211 and BIOL 0500 or BIOL 0700 or waiver; instructor approval required for all students) 3 hrs. disc

ENVS 0500 - Independent Study      

Independent Study
In this course, students (non-seniors) carry out an independent research or creative project on a topic pertinent to the relationship between humans and the environment. The project, carried out under the supervision of a faculty member with related expertise who is appointed in or affiliated with the Environmental Studies Program, must involve a significant amount of independent research and analysis. The expectations and any associated final products will be defined in consultation with the faculty advisor. Students may enroll in ENVS 0500 no more than twice for a given project. (Approval only)

ENVS 0700 - Senior Independent Study      

Senior Independent Study
In this course, seniors complete an independent research or creative project on a topic pertinent to the relationship between humans and the environment. During the term prior to enrolling in ENVS 0700, a student must discuss and agree upon a project topic with a faculty advisor who is appointed in or affiliated with the Environmental Studies Program and submit a brief project proposal to the Director of Environmental Studies for Approval. The expectations and any associated final products will be defined in consultation with the faculty advisor. Students may enroll in ENVS 0700 as a one-term independent study OR up to twice as part of a multi-term project, including as a lead-up to ENVS 0701 (ES Senior Thesis) or ENVS 0703 (ES Senior Integrated Thesis).
