Visiting Research Scientist
  		My primary research interests are in star and planet formation, focusing on the properties and evolution of protoplanetary disks and the origins of planetary systems.  I specialize in the use of infrared spectroscopy to study the chemical properties, temperature, and kinematics of molecular gas in planet forming disks around young stars, with the objective of advancing our understanding of the conditions and processes that drive planet formation.  My work makes use of observations at near-infrared to far-infrared wavelengths, ranging from high-resolution spectrographs on large ground-based telescopes, to space-based spectrographs on missions such as the Spitzer Space Telescope and the James Webb Space Telescope.
