Numerical Relativity
My area of expertise is numerical relativity, which is the use of high-performance computing methods to solve Einstein's equations of general relativity to study cosmological and astrophysical phenomena in the most extreme regimes of gravity. In short, I use computers to simulate some of the most catastrophic events in the Universe, such as the collision of black holes!
New Physics in the Strong-Field Regime of Gravity
We are in a new era of gravitational physics in which both gravitational-wave measurements and cosmological observations can be used to test fundamental physics. Moreover, recent computational developments allow us to investigate (at present largely unexplored) regimes where the gravitational force is strong – a very promising area to search for new physics. While in 91̽»¨, I will carry out a novel research program to explore how the gravitational waves that are produced in the most catastrophic events in the Universe can be used to answer some of the greatest outstanding questions in physics: How did the Universe begin? What is it made of?
