Eric joined the University of Rochester faculty in 2008 as an Assistant Professor in the Department of Physics and Astronomy. His primary research interests are the formation and evolution of planetary systems, stars, and stellar groups in our Galactic neighborhood. His recent and on-going research projects and collaborations involve quantifying and trying to understand the evolution of protoplanetary and dusty debris disks around normal stars, improving distance and age estimates to astrophysically interesting stellar, protostellar, substellar, and planetary systems, and surveys to image extrasolar planets and substellar companions to nearby stars in the near- and thermal infrared. He has also recently discovered a few new nearby young stellar groups in the solar neighborhood within a few hundred parsecs of the Sun, and is interested in investigating the recent star-formation history and kinematics of the solar neighborhood and what it can inform us about star-formation mechanisms. He also recently co-authored a paper on the observational consequences of protoplanet collisions, and recently codiscovered an extrasolar ring system (possibly a circumplanetary or "protoexosatellite" disk?) transiting a young Sun-like star.
