Research Interests

cell biology, ciliate development, electron microscopy

My laboratory concentrates on basic problems which can be best approached with the use of protozoa as either model systems or pragmatic solutions to fundamental problems in biology. They center around: 1) issues of general ecology, 2) cellular development, and 3) structure/function relationships. With respect to the latter, inasmuch as the protozoa are both cells and organisms, the emphasis has been on just what cellular adaptations have been made to accomplish life as a unicellular eukaryote. In the case of development, my laboratory has paid special attention to the role of basal bodies and centrioles in their regulation & semiautonomy during growth and cellular division. Insofar as ecology is concerned, the program of division is applied to the estimate of the growth of these organisms, the behavior of ciliated protozoa as they respond to chemical environmental cues, and finally an evaluation of the role protozoa play in the decomposition of organic wastes, particularly during the activated sludge process. The activities of my laboratory have been funded by grants from the National Science Foundation (NSF), the National Institutes of Health (NIH), the Department of Energy (DOE), and the Office of Water Resource Research (OWRR).
