I was born in St. Louis Missouri (USA) in 1968. I was exposed and began to appreciate the natural world in my youth through my studies of physics and my backpacking experiences in the Boy Scouts. I am currently a professor of Applied Physics at Caltech (Pasadena, CA) and my research is focused on demonstrating quantum phenomena at ever larger length scales. As this work has progressed, the nonesensical nature of the universe has become more sharply in focus, yet the true nature of reality has become less certain. Over the last 10 years I I have begun to spend more and more time outdoors and have deep concerns for the impact which our lifestyle has on our environment. It is clear that both our environment and our way of life are begining to change. These photographs are the record of the time spent outside, walking, often in remote terrain. I also am a very passionate glider pilot and love the fact that energy, ultimately from the warmth of the sun, together with some understanding of the natural forces can be harrnessed to carry me to altitudes higher than Mt. Everest, and for hundreds of miles.
