Who runs the world? Microbes! I’m a molecular microbial ecologist, meaning I use molecular biological techniques to ask questions and gain insight into microbial ecology. The lab’s current research investigates bacteria, viruses, and archaea in aquatic systems from mercury methylation in St. Lawrence River wetland sediments, to Bahamian coral microbiomes, and harmful algal blooms in Vermont lakes.

Courses Taught

Course Description

Ecology and Evolution
In this introduction to ecology and evolutionary biology we will cover the topics of interspecific interactions (competition, predation, mutualism), demography and life-history patterns, succession and disturbance in natural communities, species diversity, stability and complexity, causes of evolutionary change, speciation, phylogenetic reconstruction, and population genetics. The laboratory component will examine lecture topics in detail (such as measuring the evolutionary response of bacteria, adaptations of stream invertebrates to life in moving water, invasive species and their patterns of spread). We will emphasize experimental design, data collection in the field and in the laboratory, data analysis, and writing skills. This course is not open to seniors and second semester juniors in the Fall. 3 hrs. lect./disc./3 hrs. lab

Course Description

Microbiology
The microbiological principles emphasized in this class will provide students with a foundation for advanced study in many areas of contemporary biology. The course will integrate basic and applied aspects of microbiology into a study of the prokaryotic microorganisms. General principles of bacterial cell structure, function, and the role of microorganisms in industry, agriculture, biotechnology, and disease will be discussed. An independent laboratory project will stress basic microbiological techniques as applied to the isolation, characterization, and identification of microorganisms from the natural environment. (BIOL 0140 and BIOL 0145) 3 hrs. lect./4 hrs. lab./1 hr. prelab.

Course Description

Molecular Microbial Ecology
Molecular microbial ecology (MME) uses leading-edge molecular tools to study the interactions and diversity of microorganisms in the natural environment. MME covers topics ranging from ancient polar microbes, the human microbiome, and possibly life beyond Earth. This course will discuss papers that highlight modern technical approaches and form the current theoretical framework in microbial ecology. The laboratory will examine the structure (who is there) and function (what are they doing) of microbial communities in environmental samples. We will cultivate novel microorganisms and analyze nucleic acids via community fingerprinting, functional gene analysis, and the computational exploration of metagenomic datasets.  (BIOL 0140, BIOL 0145 and CHEM 0103 or 0104 or waiver) 3 hrs. lect./3 hrs. lab

Course Description

Advanced Field Biology: Place-based Global Biology Education
In this upper-level biology course, we will conduct field-based scientific observation, sample and data collection, and interpretation of biological phenomena. Students will be deeply engaged in off-campus, place-based learning linking Puerto Rico’s terrestrial landscapes to marine ecosystems, with a focus on the ecology, evolution and biogeochemistry across freshwater to marine system gradients. The course is split between time on-campus and off-campus conducting group research projects integrating field observations with data analysis. Students will collaborate and partner with local community members on intercultural projects with ethical local impact and relevance. Open to BIOL, MBBC, ESBI, BIOL-ECSC majors or waiver. (BIOL 0145 and BIOL 0140 and a 200- or 300-level BIOL class with laboratory or by waiver)

Course Description

Extremophiles: conquering Earth’s Extreme Environments
Even the most extreme environments are teeming with microbial life. From highly acidic streams to hydrothermal vents with temperatures exceeding 120ºC, microorganisms manage to not only grow, but thrive. How? We will utilize biogeochemistry and cellular biology to characterize these unique microbial processes, and their impact on ecosystems, through critical reading and robust discussion of primary literature. Student-driven research will provide opportunities for advanced oral and written communication skill development. (Any 300-level BIOL course with lab, or by waiver) 3 hrs. sem.

Course Description

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

Course Description

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.

Course Description

Gut Check: Exploring Microbiomes
Imagine there were an organ in your body with a mass similar to that of your heart, which trained your immune system, affecting your weight and perhaps even your behavior. Wouldn’t you want to know? There is such an organ — your microbiome, the collection of microbes in and on your body.
You are not alone; corals, squid, beetles, and many other organisms harbor microbiomes that generate nutrients, produce light, and defend their host organisms in the environment. Increasingly, we also understand microbiomes to be intrinsically and deeply embedded within social and environmental (in)justice. We will read I Contain Multitudes by Ed Yong, as well as other popular science and research papers to investigate these fascinating microbes.
