I teach Microbiology and Health (BIOL 2100) lecture and laboratory sections. Most of my students plan to enter allied health fields such as nursing, pharmacy, and dietetics. This microbiology course explores the biology of microorganisms: organisms too small to be seen with the naked eye. The course begins with the development of the microscope and continues with the work of early microbiologists such as Pasteur, Koch, and Semmelweise. Subsequent topics include microbial cell structure, physiology, genetics, diversity, and environmental interactions. I emphasize disease causing microorganisms with particular reference to morphological and physiological characteristics, the physical and chemical means used to control growth, and the immunological response caused by infection. In the laboratory component of the course I focus on techniques used to investigate microbial characteristics. I am particularly interested in digital photomicroscopy and biological illustration.
