Dr Sharon is originally from a small town in Northern California, USA, called Grass Valley. She moved south to pursue a BS in astrophysics at the California Institute of Technology. She completed her PhD at Rutgers, the State University of New Jersey on the molecular gas content of dusty galaxies in the early universe. Dr Sharon was subsequently a postdoctoral research associate at Cornell University in the Cornell Center for Astrophysics and Planetary Science. Prior to starting at Yale-NUS, she was the inaugural William & Caroline Herschel Postdoctoral Fellow at McMaster University in Hamilton, Ontario, Canada.
Dr Sharon is an observational radio astronomer and she studies the processes that affect star formation and galaxy evolution across cosmic time. For her work, she primarily uses synchronised arrays of radio telescopes like the Karl G. Jansky Very Large Array in New Mexico (USA) and the Atacama Large Millimeter/submillimeter Array in Chile to characterise the gas reservoirs that fuel star formation. Her work addresses why galaxies in the early universe (~10 billion years ago) have unusually high star formation rates and what role galaxies’ central supermassive black holes play in ending periods of rapid star formation.
