Professor of Biology

Courses Currently Teaching: Microbiology and Lab (BI248)

Courses Taught: Microorganisms and Society (BI133), Microbiology (BI248), Pathogenic Bacteriology (BI348)

Research Interests: My students and I are studying the effects of environmental mercury in various systems (soil, sphagnum bogs, salmonid gastrointestinal tracts, and two species of fish pathogens) and how this toxic metal is providing selective pressure in the evolution of mercury-resistant bacterial strains.  In selecting for mercury-resistant microbial strains, the metal is also responsible for the co-selection of antibiotic-resistance determinants because genes responsible for both antibiotic- and mercury-resistance are linked genetically.  Mercury is a by-product of various industrial applications, in particular, it is found in emissions from coal-fired electrical generation plants in the Midwest.  Atmospheric mercury is then deposited in the Maine environment via liquid precipitation.  Hence, over time, not only does mercury pose a serious environmental health threat, bacterial strains are evolving that show an increased incidence of resistance to antibiotics.  Conceivably, these genes could then be transferred horizontally to pathogens, making treatments of infectious disease with antibiotics non-efficacious.

Thom Klepach

Visiting Assistant Professor of Biology

Courses Currently Teaching: Anatomy and Physiology of Yoga and Mindful Practice (BI147)

Courses Taught: Biochemistry of Food (BI135),  Anatomy and Physiology of Yoga and Mindful Practice(BI147), Biochemistry of Food (BI198), Human Anatomy and Physiology (BI265j)

Research Interests: In the past I have explored the structural biology of carbohydrates particularly the time dependant conformational reorientations they undergo using a combination of ab initio theoretical calculations and experimentally measured 13C based NMR spin-spin coupling constants. More recently my work with students has been related to various aspects of Anatomy, Physiology, and Medicine, particularly 3D anatomical imaging and modeling.

Chris Moore

Assistant Professor of Biology

Courses Taught: Introduction to Ecology (BI271), Ecology & Evolution of Infectious Disease (BI298), Ecological Modeling (BI382)

Research Interests: I am an ecologist concerned with the distribution and abundance of organisms. My specific area of study is how the distributions and abundances of organisms are affected by positive species interactions known as mutualism. Mutualism, sometimes referred to as cooperation, is where 2 or more species directly benefit from each other (in currencies such as survival or reproduction), in cases such as plants and pollinators, coral and zooxanthellae, and plants and seed-dispersing animals. I use both empirical and theoretical approaches to my work, and I am always eager to work with interested and motivated students.

Suegene Noh

Assistant Professor of Biology

Courses Currently Teaching: Genomics (BI278)

Courses Taught: Evolution and Diversity (BI164), Genomics (BI278), Evolutionary Analysis (BI320), Advanced Genomics (BI345)

Research Interests: I am interested in the evolution of phenotypes and genomes that occurs when organisms adapt to changes in their social environments. I work with Dictyostelium social amoebae that aggregate to become multicellular when they are starved. Some of these amoebae carry endosymbiotic bacteria and my ongoing research focuses on understanding this symbiotic relationship and how it affects social dynamics among amoebae.
