I’m an Einstein fellow at Berkeley Lab (LBNL), and a member of the Theoretical Astrophysics Center at UC Berkeley. My research is primarily in theoretical and computational relativistic astrophysics, in particular the dynamics of magnetically dominated plasmas around neutron stars and black holes, which I study using global numerical simulations. I’m also interested in theoretical cosmology, MHD and plasma physics in general, and high-order numerical methods for nonlinear systems.
I’m the developer of PHAEDRA, an MPI-parallel pseudospectral simulation code which solves the equations of general-relativistic force-free electrodynamics (vanishing-inertia or ultra-relativistic MHD). I’ve used this code to study the isolated pulsar magnetosphere; magnetar giant flares driven by slow surface deformation; black hole Blandford-Znajek jet launching using disc-thickness-scale magnetic flux systems; the effect of curved spacetime on the distribution of pair production across a pulsar’s polar cap; and the interaction between the magnetosphere of a millisecond pulsar and a surrounding accretion disc. I’m working on a second code for magnetospheres in GR, using the multidomain staggered Chebyshev method (also known as spectral differences, and a close cousin of discontinuous Galerkin schemes).
I was recently a postdoc in the Dept. of Astrophysical Sciences at Princeton University, where I worked with Anatoly Spitkovsky as part of the Max Planck-Princeton Center for Plasma Physics. I finished my PhD at Columbia University in 2012, writing a dissertation with Andrei Beloborodov and Lam Hui, and received an MPhys from Oxford University in 2006.
