I host the award-winning television adventure series Meteorite Men on Science Channel, which is currently in its third season. I am also a science writer, meteorite specialist, photographer, adventurer, and the owner of Aerolite Meteorites LLC—one of the world's foremost providers of quality meteorite specimens for researchers and collectors worldwide.

I am the author of the book Meteorite Hunting: How To Find Treasure From Space, and publisher of the Oscar E. Monnig Meteorite Collection Catalog. I have written more than 100 published articles on meteoritics, paleontology, astronomy, adventure travel, history, and the arts. My work as appeared in Astronomy, Sky & Telescope, Wired, Seed, Rock & Gem, Geotimes, Meteorite magazine, Reader's Digest, American Theater Arts, Mechanical Engineering, The Field Guide to Meteors and Meteorites, and many other national and international publications. I am the author of Meteorwritings, a science column on Geology.com, and the science and arts blog, The Logical Lizard, for TucsonCitizen.com. [Complete bibliography]

I have been actively involved with meteorite recovery, identification, and collecting since 1994. I have found meteorites on four continents, and worked with most of the world’s major meteorite institutions including The Natural History Museum, London; The American Museum of Natural History, New York; The Institute of Meteoritics at UNM, Albuquerque; The Center for Meteorite Studies at ASU, Tempe; and the Oscar E. Monnig Meteorite Gallery at TCU, Fort Worth.

I am a professional member of The Explorer’s Club, the Electronic Frontier Foundation, the Association of Applied Paleontological Sciences, the International Dark-Sky Association, and the Society of Southwestern Authors. The minor planet 132904, discovered at Mount Palomar, was named after me in 2010.

Meteorite hunting has taken me to forty-five countries and some of our planet’s most remote locations in search of elusive and valuable space rocks, including Chile’s Atacama Desert, the Australian Outback, Iceland, Norway, Sweden, rural Mexico, the Middle East, and across the Arctic Circle in northern Siberia onboard an ex-military Russian helicopter.

I was born on 14th street in Manhattan and grew up in London, England. I studied geology, astronomy, photography, writing, and design in London, Boston and New York, and now reside in the Sonoran Desert of southern Arizona with one cat and no children.
