Research

I study stellar mass compact binaries containing white dwarfs, neutron stars, or black holes. These are potential sources for gravitational wave detectors such as LISA and LIGO. My research focuses on the formation scenarios for these objects and how gravitational radiation observations can help distinguish between them. This covers a broad range of astrophysics, including stellar evolution and mass transfer in binary systems. These systems may also form dynamically, so I also study the evolution of dense stellar clusters such as globular clusters and galactic nuclear star clusters. Globular clusters are some of the oldest stellar clusters known, while the evolution of galactic nuclear star clusters is tied to the growth of galaxies over cosmological time. I am beginning to look into cosmological models to determine the evolutionary history of these clusters.
