cell biology, ciliate development, electron

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).
