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.

Winter in Rocky Mountain National Park

Although the season is officially still Autumn, at the higher elevations of Colorado it is winter. I drove to Rocky Mountain National Park on a sunny Sunday morning. It is only an hour from Boulder, Colorado. The first stop was to get a picture of the “Chapel on the Rock” with Mt. Meeker in the background. Then it was into the park to get more pictures. Winter view of the Big Thompson River in Moraine Park; Winter Trail to Storm Pass along road to Bear Lake; and a Winter Panorama of Longs Peak taken along Colorado Highway 7
