Computer simulation: how galaxies reionize the universe
My research interests range from General Relativity to physics of the interstellar medium to cosmology. Right now, for most of the time I work on numerical cosmological simulations, including (but not limited to) simulating galaxy formation, formation of supermassive black holes, and evolution of the intergalactic medium. I like doing numerics and working with a computer. This often includes quite sophisticated visualization of the simulation results, so, I guess, I am a little bit a movie director as well. Isn't it great to direct a movie where galaxies and stars are the actors?!
