About me

I am an associate professor in the Department of Physics at California State University, Fullerton. My current research interests focus on using numerical relativity to model sources of gravitational waves, such as merging black holes. I join professors Jocelyn Read, Josh Smith, and Al Agnew in Cal State Fullerton’s Gravitational Wave Physics and Astronomy Center (GWPAC), and I also am a member of the Simulating eXtreme Spacetimes (SXS) collaboration and the LIGO Scientific Collaboration.

GWPAC and the SXS collaboration are contributing to LIGO’s discovery of gravitational waves.


At Cal State Fullerton, my research goals focus on modeling sources of gravitational waves using numerical relativity. Gravitational waves—ripples of spacetime curvature—are opening a new window on the universe. The Advanced Laser Interferometer Gravitational-wave Observatory (Advanced LIGO) has observed the first gravitational waves passing through Earth, which came from merging black holes. My students and I use supercomputers to simulate colliding black holes using the Spectral Einstein Code (SpEC), and we are particularly interested in modeling merging black holes that spin nearly as fast as possible and in responding to LIGO observations. I recently have begun using supercomputers to model thermal noise in LIGO mirrors, with the goal of helping to improve the sensitivity of next-generation detectors, and exploring how well gravitatioanl-wave detectors can measure rapid black-hole spins.

I am contributing to the development of SpECTRE, the SXS Collaboration’s next-generation numerical-relativity code. Jocelyn Read, Josh Smith, and I area also contributing to charting a course for the next generation of gravitational-wave science in the United Sates, looking at concepts like Cosmic Explorer.

Starting in 2018, I am leading an annual one-week summer workshop that introduces students from local community colleges to gravitational waves and high-performance computing.

What merging black holes look like

The source of LIGO’s first observation of gravitational waves was a pair of merging black holes. This movie shows what the merging black holes would look like up close, in slow motion (about 100 times slower than real time). Credit: SXS Collaboration.
