About Me


I am an observational astrophysicist. My main research areas are extragalactic astrophysics and data intensive astronomy. I also have broad interests in other fields of science, especially black holes, cosmology and dark matter. I particularly enjoy exploring original ideas and studying unexplained phenomena in the Universe.


I currently hold a NASA Hubble Fellowship (hosted by Johns Hopkins University), an independent postdoc Fellowship awarded to conduct original research. Prior to this fellowship, I was a postdoc fellow at JHU between 2011 and 2014. I obtained my Ph.D. in Physics at New York University in May 2011.


I have projects at different levels suitable for undergraduate, junior and senior (thesis) graduate students. If you are interested in learning more about them, please feel free to drop me a message or stop by my office (Bloomberg 520).
