David is an Associate Astronomer at STScI. He obtained his PhD in astrophysics from Caltech and was previously a Hubble Fellow at UCLA and a Dunlap Fellow at the University of Toronto. His research focuses on the evolution of galaxy structure and kinematics from the Local Group to high redshift, with particular emphasis on optical/IR spectroscopic studies of turbulence and gas outflows in star forming galaxies. He is the lead data scientist for the SDSS-IV MaNGA project, which is obtaining integral-field spectroscopy for 10,000 nearby galaxies. David is a member of the JWST MIRI instrument team, where he leads the development of the MRS integral field spectrograph.
