For most of my career I have studied the tenuous gas surrounding galaxies at the University of Colorado's Center for Astrophysics and Space Astronomy. I have also analyzed data from the Rosetta mission to Comet 67P/Churyumov-Gerasimenko at the Southwest Research Institute.

In 2017, NASA's New Horizons team observed their extended-mission target briefly pass in front of a background star. I helped, and NASA has video to prove it.

About Me

I live with my wife and daughter in Longmont, CO. We enjoy traveling the world and exploring the Colorado mountains. I grew up in Ohio and Virginia with my two brothers, and attended the University of Virginia before moving to Colorado for graduate school. I have never outgrown my childhood love of science-fiction and fantasy novels.
