Research Interests

My recent research is in the area of millimeter-submillimeter observations of such galaxies as mergers, barred spirals, and starburst galaxies for the purpose of understanding the structure, dynamics, and evolution of galaxies. The intersteller medium visible at millimeter-submillimeter wavelengths is the raw material for star formation, a tracer of galactic dynamics, and a driver of galaxy evolution through its motion within galaxies. Millimeter-submillimeter interforometry techniques are also in my research interests. My current research projects mainly use Submillimeter Array (SMA) and the Atacama Large Millimeter-submillimeter Array (ALMA).
