Biographical Sketch

Dr. Sheridan has a wide variety of interests within the fields of Biochemistry, Microbiology, and Bioinformatics. Although a Biochemist at heart, Dr. Sheridan and his students have active research projects encompassing the molecular adaptation of enzymes to extreme conditions (especially cold), the diversity and activity of microbial populations in extreme environments, the production of bioactive compounds by microorganisms that could be useful in industry and biotechnology, and the pathogenesis and control of various disease-causing organisms. Dr. Sheridan has been at Idaho State University since 1991. Outside of his teaching and research interests, Dr. Sheridan enjoys hiking and camping with his family; making beer, cheese, yogurt and other tasty microbial fermentation products; and anything to do with Celtic music and culture.
