Research
Our current descriptions of black holes are notorious for being singular at r=0. My research goal is to find an alternative description that is singular-free. In my MSc research, we were able to construct a regular solution to Einstein's equations which is stable for linear fluctuations in the geometry, pressures, and densities.
In my Ph.D. research, we are developing this model and examining new ideas.
