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.

Seven-Years Ago (05-September-2006) — Washington

Gone to See America 2006 Driving Tour. Day 11:  Lake Chelan, Washington.

Female Mallard Duck on Lake Chelan in Washington from rear deck of the Lady of the Lake Ferry. Image taken with a Nikon D200 camera and 80-400 mm VR lens (ISO 400, 400 mm, f/9, 1/320 sec). I took this image with my first DSLR while driving across the country back in 2006. I really like the catch light in the eye, and the ripples and reflections. This image is one of the reasons that I decided to spend more time with photography.
