My primary interest is the study of the properties of molecular clouds within the Milky Way. Molecular gas can be readily probed using millimeter and submillimeter wavelength spectroscopy. Such data can provide information on the mass, density, temperature, spatial structure, kinematics and chemistry of the gas within these molecular clouds. Much of my observational work in the past was done using the Five College Radio Astronomy Observatory 14-m telescope, the Submillimeter Wave Astronomy Satellite (SWAS) and Herschel Space Telescope. My current studies are making use of the Large Millimeter Telescope (LMT) and ALMA.
