I am currently a Lagrange postdoctoral fellow in astronomy at the Institut d'Astrophysique de Paris (IAP)  with funds from the Institut Lagrange de Paris (ILP). I received my Ph.D. in Physics from Massachusetts Institute of Technology in 2008. My thesis advisors were  Professors Max Tegmark and Alan Guth. You can find my Ph.D. thesis here. I then worked as a postdoctoral fellow at the University of Texas at Austin (September 2008 - August 2012), with Prof. Paul Shapiro, before I moved to Paris.

I am a theoretical and computational astrophysicist. My research interests are primarily in the Universe at high redshift, especially the epoch of reionization and the dark ages. I have focused on 21cm tomography and  numerical simulations of reionization in recent research. Specifically, I have been investigating what we can learn about the evolution of the Universe during these epochs using the redshifted 21cm line, and how we can improve our methods of predicting 21cm signals from simulation data in order to fulfill the promise that 21cm tomography can constrain or test cosmological and astrophysical models to high precision. You can learn more details about my research here.

In my research I have developed a few Fortran codes that facilitate the application of N-body and radiative transfer simulations data.
