I am a Research Fellow in the Centre for Inertial Fusion Studies (CIFS), working in computational High Energy Density Physics. My research covers Inertial Confinement Fusion (ICF) and Magneto-Inertial Fusion (MIF). For ICF, I model experiments carried out on the NIF laser at Lawrence Livermore National Laboratory and the OMEGA laser at the Laboratory for Laser Energetics. For MIF, I study experiments carried out on the Z machine at Sandia National Laboratories.

Research topics that I am currently interested in include:

  • How can we measure the temperature and density of burning plasmas in ICF experiments? 
  • How do magnetic fields affect thermonuclear burn?
  • How can we make efficient, intense neutron sources in the laboratory?
  • How can we use Quantum Computers in Plasma Physics?

Here I am talking with Varsha Krishnan about my life as a Physicist, and here is a blog post about some of my current research.
