International Activities

Country of Interest

I have long-standing connections to several countries. I have professionally visited Egypt 3 times and have had 7 graduate students from four Egyptian universities where I am a visiting professor. These have all been supported by their governments and have worked on a variety of anatomical topics, mostly in cardiovascular, digestive and reproductive systems.

I have visited Jordan to speak on the subject of the Internet as a teaching tool, and hosted about a dozen sabbatical visitors from these two countries. In 1998 I was a Fulbright Scholar in India, where I taught sensory physiology at Mangalore University. I have attended any number of international meetings, usually anatomy related, as a speaker, most recently in Sicily. I am trying to establish a course on wildlife biology that would be based in South Africa.

I'm the author of a very widely-used and extensive Internet teaching site in histology.


French and Italian, enough to order a meal, ask directions and use the Metro. I can read French reasonably well and can manage technical Italian with the aid of a dictionary.

Future Research

I have a new graduate student coming from the Jordan University of Science & Technology who will be working on the subject of rodlet cells in fishes, later this year. I am currently working on the development of a web-based pathology site similar to the histology site.
