I am a scientist by training (Eckerd College, BSc; Caltech, Ph.D.). I worked for 27 years as a Chemist in the Pharmaceutical Industry developing processes to manufacture medicines for human and animal health. I now spend my time as a photographer and world traveler. My interests in photography include the natural world, wildlife, landscapes, skyscapes, and seascapes. I have traveled to over 50 countries over the last 10 years, often on Semester at Sea voyages. While at home in New Jersey, I spend time on a home renovation project and expanding my wildflower garden/meadow.
