FROM LINKEDIN I am an astronomer whose research focuses on improving our understanding of star formation. I am an multi-wavelength observer who uses ultraviolet, optical, infrared, and radio observations from a wide range of facilities (including the Hubble Space Telescope, Spitzer Space Telescope, and Atacama Large Millimeter/Submillimeter Array) to answer questions related to star and cluster formation. Broadly, I seek to understand star formation behavior at spatial scales ranging from that of galaxies down to individual star-forming complexes through the combined study of stellar populations and the interstellar medium. Specifically, I study the formation and evolution of star cluster populations and young pre-main sequence star populations in nearby galaxies, focusing on how star and cluster formation processes depend on galactic environment. Citizen science and crowdsourcing are important tools in my research, and I am proud to collaborate with volunteers and researchers in the Zooniverse community.
