I work on the observational and theoretical aspects of Core-Collapse Supernovae (CCSNe), which are the spectacular deaths of stars with initial masses greater than 8 Suns combined. My research mainly focuses on understanding their progenitor stars, explosion mechanisms, and the circumstellar environments using multi-wavelength observations and hydrodynamic modeling. I also enjoy science communication and outreach to share the wonders of the universe with the public.
