I am an ITC postdoctoral research fellow at the Institute for Theory and Computations (ITC) at the Harvard-Smithsonian Center for Astrophysics (CfA).

I specialize in numerical and analytic modeling of key physical processes in the interstellar medium (ISM). My goal is to obtain a deep understanding of how star formation operates in galaxies, and how the forming stars regulate the evolution of galaxies across cosmic times.

Interestingly, star formation and galaxy evolution are connected. Stars form in the ISM through the combined act of gas radiative-cooling followed by gravitational fragmentation and collapse. During their lives, the stars heat, ionize and disperse interstellar clouds. At their deaths massive stars inject energy and momentum by supernova explosions, heating and ionizing the gas, producing cosmic-rays, and generating turbulence. Altogether, these processes introduce a negative feedback-loop for star-formation. On the other hand, over cosmic time-scales, stars also facilitate gravitational collapse by gradually enriching the ISM with elements, which act as efficient gas coolants.

I combine multi-physics hydrodynamics simulations with analytic techniques to study the process of star-formation and galaxy evolution. I collaborate with observers to compare theory with observations in our Galaxy and in external galaxies. An interesting aspect of my studies is that it is inter-disciplinary, involving knowledge from different fields: chemistry, turbulence, atomic physics, and cosmology.
