I am a Principal Analyst at the Southwest Research Institute in Boulder, Colorado, where I plan and execute stellar occultation campaigns for NASA's Lucy and New Horizons missions, develop science sequences for Lucy, and analyze data for New Horizons and Rosetta. I have also studied the tenuous gas surrounding galaxies at the Center for Astrophysics and Space Astronomy using the Hubble Space Telescope's Cosmic Origins Spectrograph.

Lucy Occultations

The Lucy mission will visit six of Jupiter's Trojan asteroids. We're observing them all with small, portable telescopes.

2017 Arrokoth Occultation

In 2017, I helped the New Horizons team watch Arrokoth briefly pass in front of a background star. There's video to prove it.

2018 Arrokoth Occultation

We observed Arrokoth from Senegal in 2018, where we met the president and were featured in the New York Times.

About Me

I live with my wife and daughter in Longmont, CO. We enjoy traveling the world and exploring the Colorado mountains. I have two younger brothers, was raised in Ohio and Virginia, and attended the University of Virginia and the University of Colorado. I have never outgrown my childhood love of science-fiction and fantasy novels.
