Bio

I am an evolutionary biologist interested in how plants adapted to radically different environmental conditions upon colonization of new ecosystems. I am especially interested in the genomic changes associated with the transition from terrestrial to aquatic environments.

Because internal and external microbial communities are invariably intertwined with plants in natural environments, I am also interested in the broader consequences of the movements of plants and their associated microbiomes between habitats, whether transitions between emerged and submerged environments, or introductions of non-native plants to new locations.

Currently Teaching

BIOL-123

Introduction to Biology: Organisms and Ecosystems

3 Credits

This course serves as an introduction to biology for majors, focusing on the organismal, population, and ecosystem levels. Major themes include: evolution, structure and function, information flow and storage, pathways and transformations of energy and matter, and systems. The course also focuses on developing core competencies, such as applying the process of science, using quantitative reasoning, communicating, and collaborating. Small-group recitation sessions will develop study skills, introduce faculty research opportunities, and foster communication between students, peer mentors and teaching faculty.

BIOL-295

Biology Research

1 - 4 Credits

This course is a faculty-directed student project or research involving laboratory work, computer modeling, or theoretical calculations that could be considered of an original nature. The level of study is appropriate for students in their first three years of study.

BIOL-298

Biology Independent Study

1 - 4 Credits

This course is a faculty-directed tutorial of appropriate topics that are not part of the formal curriculum. The level of study is appropriate for student in their first three years of study.

BIOL-301

Undergraduate Teaching Experience

1 - 4 Credits

This course allows students to assist in a class or laboratory for which they have previously earned credit. The student will assist the instructor in the operation of the course. Assistance by the student may include fielding questions, helping in workshops, and assisting in review sessions. In the case of labs, students may also be asked to help with supervising safety practices, waste manifestation, and instrumentation.

BIOL-495

Advanced Biology Research

1 - 4 Credits

This course is a faculty-directed student project or research involving laboratory or field work, computer modeling, or theoretical calculations that could be considered of an original nature. The level of study is appropriate for students in their final two years of study.

BIOL-498

Advanced Biology Independent Study

1 - 4 Credits

This course is a faculty-directed tutorial of appropriate topics that are not part of the formal curriculum. The level of study is appropriate for student in their final two years of study.

BIOL-573

Marine Biology

3 Credits

This course explores marine biology by focusing on the diversity of life and influence of oceanographic phenomena on the various ecosystems. Morphological and physiological adaptations along with environmental threats will also be investigated.

BIOL-673

Marine Biology

4 Credits

BIOL-798

Grad Biology Independent Study

1 - 4 Credits

This course is a faculty-directed, graduate level tutorial of appropriate topics that are not part of the formal curriculum.

ENVS-790

Environmental Science Thesis

1 - 4 Credits

The thesis option will be available to environmental science graduate students only with prior written approval of program faculty. Students will submit a proposal to a faculty member who agrees to serve as the student's thesis committee chair. The proposal will describe the basic research question to be investigated and the experimental protocols to be employed. Proposals will be reviewed by the program faculty who will give permission to register for thesis credit. This course may be taken several times over the course of a student's graduate program, for variable credits. A written thesis and oral defense are required at the completion of the thesis research.

ENVS-791

Continuation of Thesis

0 Credits

Continuation of Thesis
