I grew up in Miami and Ft. Lauderdale, Florida. Before going to college I worked at

everything from being an assistant trainer at a sea aquarium, a scuba diver, an import

company jack-of-all-trades, a common seaman on a Bahamas cruise ship, and a clarinet

tutor. I completed a bachelors degree and masters degree in mathematics at San Diego

State University. In my masters thesis I proved some old algebraic topology results in

a new way using spectral sequences. I went to UCLA for doctoral work, obtaining a PhD

degree in Applied Mathematics in 1977. My dissertation involved development of a

mathematical model for the electrical activity of a nerve in the worm Myxicola, and

proving the existence of propagating action potentials using topological ideas and

perturbation theory. My first academic appointment was at Texas A&M University, then in

1981 went to the Department of Mathematics at SUNY at Buffalo where I got promoted in

1983 to associate professor, and again at the beginning of 1990 as full professor. I

spent sabbatical time in the 1980s at Oxford University, Heriot-Watt University, and

National Institutes of Health. I was department chair from 1997-2000. I left Buffalo

in 2000 to take the appointment as professor and chair of Mathematics and Statistics

Department at UMBC. I stepped down as Chair in July, 2006, and continued on as

Professor of Mathematics until September, 2014, at which time I retired. I am now Emeritus

Professor, and at present cruising the east coast of the US on my motor yacht AfterMath.
