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.

Wintertime Nature in the Sourland Mountain Preserve.

We had a bit of snow last night. I went for a short walk in the Sourland Mountain Preserve. When I got home I found this young deer eating my shrubs.

Backyard Winter Night Sky Over New Jersey: Time-lapse Video

The ClearSky folks didn’t have a good forecast for the whole night, but I still recorded the night sky looking south. You can see the clouds kept passing over, so no star trails.

Winter Indoor Nature in New Jersey: Stink Bug Eating Pink Grapefruit.

The invasive stink bugs that invaded Pennsylvania have expanded into New Jersey. They come into houses during the winter to stay warm.  As seen here, one is feasting on a pink grapefruit that I just brought back from Florida.
