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 include the natural world, wildlife, landscapes, sky, and seascapes, travel, and astrophotography. I look for unique ways of viewing the world and presenting my images. I have traveled to over 55 countries in six continents, often on Semester at Sea voyages. While at home in New Jersey, I spend time on home renovation and expansion of a wildflower garden/meadow.

Gone to See Europe 2014. Day 58: Semester at Sea, Summer 2014 Semester Voyage. Saint Petersburg, Russia.

On our last day in Saint Petersburg, I attended a Master Cooking Class. I actually took more pictures than doing any cooking. The Russian food (Stuffed Cabbage and Borscht) we prepared was great, and I used the pictures to create this Time-Lapse Video.
