Jet-driven H₂ and ionized outflows in 3C 305
JWST resolves shocks, warm molecular outflows, and faster ionized outflows where the compact radio jet terminates inside the galaxy.

Current focus
Connecting energetic engines to their galactic environments
At the Space Telescope Science Institute, I work with Dr. Patrick Ogle on JWST integral-field spectroscopy of radio galaxies. We map shocked molecular and ionized gas, outflows, and the energetics of jet–ISM interaction.
Previously, I contributed to the CIRADA collaboration at the University of Manitoba, developing radio-continuum processing pipelines and science-ready products for surveys including VLASS. I earned my PhD at NCRA–TIFR with Prof. Preeti Kharb.
