Alex Teachey is a Distinguished Postdoctoral Fellow at the Academia Sinica Institute of Astronomy & Astrophysics in Taipei, Taiwan. His work as an observer has taken him across the entire electromagnetic spectrum, having worked with radio, optical, near-infrared and gamma-ray data, studying stellar activity, exoplanets, exomoons, and giant molecular clouds in the Milky Way.
A native of Richmond, Virginia, Alex lived in New York City for 17 years, where he earned his bachelor’s in Physics (CUNY Hunter College), and his PhD in Astronomy (Columbia University) as a National Science Foundation Graduate Research Fellow. Prior to attending Columbia he worked as a researcher at the American Museum of Natural History, and at the National Radio Astronomy Observatory in New Mexico. He was a co-host of the monthly outreach event Astronomy on Tap New York City, and now co-hosts Astronomy on Tap Taipei alongside other ASIAA postdocs.
These days his primary research focus is on the search for exomoons — moons in other planetary systems outside our Solar System. Most notably, in 2017 Alex led the first ever Hubble Space Telescope observation of a candidate exomoon system, Kepler-1625b.
