My current research focus at Argonne National Lab involves differentiable modelling of galaxy formation and evolution, with the goal to jointly forward-model complex multi-wavelength multi-survey data from different telescopes, to better constrain galaxy formation physics and cosmological parameters. A crucial service work generated by this research is the creation of extremely realistic mock catalogues that are invaluable for the calibration and validation pipelines in different surveys, such as DESI, Rubin, Roman, etc. This invited talk at the Mock-NYC 2026 conference, offers a snapshot of where I was in my postdoctoral research as of mid-January, 2026.

This recorded video of an invited talk [Feb 04, 2026] at Clemson University's Department of Physics and Astronomy online seminar gives a very brief overview of my PhD thesis work at Yale.

The following are a few of my key highlights from my past research work: either demonstrating some particular methodology or showcasing a specific result.
