I’m an MPA fellow at the Max Planck Institute for Astrophysics in Garching, Germany, working on every theoretical aspect of dynamical interactions between stars and black holes in various astrophysical settings and their observational signatures, including gravitational waves and electromagnetic signatures. My research areas are

  • Multi-messenger transients, such as tidal disruption events and stellar collisions
  • Active galactic nuclei
  • Multi-body dynamical interactions
  • Gravitational waves
  • Hot jupiters
  • Stellar binary evolution, such as stable mass transfer

In particular, my endeavor for the last couple of years has been towards bringing up our understanding of multi-body dynamical interactions and transient formation in those beyond the conventional picture.

I am a former drummer in a few different bands, passionate tennis player and snow boarder. See About Me!
