My research focuses on the multi-wavelength observations and modeling of a variety of high-energy cosmic transient sources, including gamma-ray bursts, gravitational wave sources, magnetars, and tidal disruption events. My observational work covers the extremes of the electromagnetic spectrum, namely with gamma-ray satellites (e.g. Fermi Gamma-ray Space Telescope) and radio telescopes (e.g. VLA, WSRT, LOFAR, MeerKAT); and I am the Project Scientist of SCORPIO, a new instrument on the optical/near-infrared Gemini Observatory. My modeling efforts are focused on extracting physical parameters of transient sources from multi-wavelength observations, using state-of-the-art computational techniques. I have (co-)supervised half a dozen graduate and twenty undergraduate students, who have worked on all areas of my research. I am also active in astronomy and physics outreach, to increase community engagement and stimulate an interest in science.
