  • Astrophysical magnetic fields influence star formation, turbulence, propagation of cosmic rays, polarized radiation and heat transport
  • Magnetic reconnection explains solar flares, gamma ray busts, acceleration of energetic particles. We proposed a model of reconnection that explains the observations
  • Astrophysical fluids are turbulent and magnetized. Magnetic turbulence allows fast heat conduction, scatters cosmic rays, creates foregrounds that interfere with cosmic microwave background measurements
  • Energetic particles come from the sun and galaxy, and can damage electronic equipment. I study acceleration of cosmic rays by shocks and reconnection
  • Astrophysical environments are dusty. We identified a new type of emission from dust that interferes with background radiation
