Research Interests

I am interested in the physical processes responsible for how stars evolve, die, and affect the Universe during their journeys. My focus has been on:

  • Progenitors of stellar explosions, such as Supernovae and Gamma-ray bursts
  • Evolution of massive stars across cosmic time
  • Outflows and atmospheres of massive stars
  • First stars and populations at low metallicity, their fates, and their impacts on the Universe

I have been employing theoretical and observational approaches, combining multi-disciplinary techniques such as:

  • Multi-dimension radiative transfer and hydrodynamical modeling of stellar atmospheres and winds
  • Numerical models of stellar structure and evolution
  • Observations using optical interferometry, multi-wavelength spectroscopy and photometry
