waves emitted by compact object (black hole and neutron star) mergers can For my research I develop methods and conduct large simulations to understand what gravitational waves emitted by compact object (black hole and neutron star) mergers can teach us about the formation, lives, and explosive deaths of massive stars throughout cosmic history My interdisciplinary work combines the fields of statistics, data science, and astrophysics to quantify uncertain physics in these large computational simulations, and tackles the key bottleneck in gravitational-wave astrophysics: the “Uncertainty Challenge” with the ultimate goal to learn about fundamental physical processes in our Universe in the new Big Data gravitational wave era.
