Ke Wang observes high-mass star formation at high-resolution. He is an expert in submillimeter interferometry and has served in the European ALMA Regional Center and the SMA operations team for more than 5 years. His research characterizes the initial conditions of high-mass star formation throughout the Galaxy by observing various samples of molecular clouds in different Galactic environments. Observations at multiple scales are made using submm/mm/cm interferometers including ALMA, SMA, and VLA, and space- and ground-based single-dish telescopes including Herschel, GBT 100m, Effelsberg 100m, Nobeyama 45m, IRAM 30m, JCMT 15m, APEX 12m, CSO 10m, and SMT 10m.
