Research Activities

I am a Ph. D. student in the Extragalactic Astrophysics Research Group of ETH Zurich, supervised by Professor Marcella Carollo. My research focuses on the formation and evolution of galaxies across cosmic time. In particular, I study galaxies at the peak of cosmic star formation activity (z~2), using both observational data from Hubble Space Telescope and Very Large Telescope and cosmological zoom-in simulations.
