Research interests

My research seeks to understand the physical parameters and processes that most influence the evolution of galaxies. I examine the gas and star formation properties of nearby galaxies, focusing particularly on galaxies in groups and clusters where evolution is likely to be accelerated by environmental effects.

I am a member of the ALFALFA Team, led by Riccardo Giovanelli and Martha Haynes at Cornell University. The ALFALFA (Arecibo Legacy Fast ALFA) project used the Arecibo Observatory 305-m telescope near Arecibo, Puerto Rico, to search for emission from atomic hydrogen (HI) in galaxies.

I led the NSF-Funded Undergraduate ALFALFA Team, a consortium of 24 institutions participating in ALFALFA research from 2008-2022 and continue as senior personnel in the current NSF-supported program led by my colleague Dr. Joe Ribaudo (Providence College). The program includes an Annual Undergraduate ALFALFA Workshop at Green Bank Observatory. Read more about the grant in Ribaudo et al. 2023, Koopmann et al. 2020, Troischt et al. 2016, and Odekon 2015.
