I work on quasar proximity zones during reionization. I run radiative transfer cosmological simulations to study the effect of quasar radiative feedback on surrounding galaxies. I also write 1D radiative transfer code to study detailed features in the quasar absorption spectra to study the properties of IGM and the quasar. This research has been selected by the NASA FINESST program.
Previously I also worked on galaxy clusters in both observation and simulation.
