Research Interests： I work on investigating X-ray Binary systems (XRBs) using a variety of different techniques. In particular our group is studying High Mass X-ray Binaries (HMXRBs) in the Magellanic Clouds companion galaxies to the Milky Way. Publications： "Hard X-ray observations near Ariel 1118-61."
