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.

Thirteen-Years Ago (27-August-2006) — Michigan

Gone to See America 2006 Driving Tour. Day 2: Northern Michigan.

My first images with a new Nikon D200 camera on this road trip west. Quick stop in Mackinaw State Forest, then some pictures of the Mackinac Bridge before crossing it to the Upper Peninsula. Finally a stop at Pictured Rock National Lakeshore. I have memories of crossing the Mackinac bridge soon after it opened as a small child. All of the images have been reprocessed with currently available software.

Monday (26-August-2019) — New Jersey

Backyard Summertime Nature in New Jersey.

There were more than a dozen deer in my yard this morning. Lots of teenage fawns, still with spots. They spend their time nibbling on the wildflowers just outside the electric fence. At one point I saw one jump back after touching its nose to the electric fence. A bit later, I saw one of the fawns with “mile-a-minute” vine sticking to its side. Helping to spread this invasive vine.
