Brief Biography

I started at UM in the former Dept. of Zoology (now SBE) in the fall of 1979. My research initially was on circadian and ultradian rhythms in Drosophila, ultimately evolving into work with cardiac physiology in the same organism. Our lab has worked out the fundamental system of ion channels driving pacemaking in this organism. Among other things, we have shown that melatonin increases the regularity of heartbeat to an extraordinary extent. My work with the analysis of biological signals resulted in an appointment as Cooperating Professor of Mathematics and Statistics, and Bioresource Engineering. I retired from active employment as an Emeritus Professor, but continue my research in this field at the theoretical level.
