  • Strong gravity—I understand how objects behave when general relativity is relevant. This includes extreme situations, such as black holes and neutron stars, and candidate theories of quantum gravity.

  • Numerical methods—I have developed novel numerical methods targeted at improving the scalability of relativistic astrophysics calculations on high-performance computing systems

  • High-performance computing—I have participated in the development of and contributed to codes that scale to almost a million cores.
