About Me

I am an astrophysics PhD student at Rutgers University working with Dr Alyson Brooks. My primary research interests are using cosmological hydrodynamical simulations to study the connection between the evolution of both galaxies and the massive black holes often found at their centers.

I use high resolution cosmological simulations to understand how massive black holes may form, grow, and (directly or indirectly) affect the population of dwarf galaxies we see today. This work is done in collaboration with the N-Body Shop.

I also study triggers of supermassive black hole activity in cosmological zoom simulations. Generating mock images of simulated galaxies allows me to characterize how observational biases may affect conclusions for observers versus what we find in the simulation.

Finally, I have an interest in applications of machine learning and new computing techniques in astronomy.
