I am a 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 Nicholas and Lee Begovich Center for Gravitatinal-Wave Physics and Astronomy (GWPAC), and I also am a member of the Simulating eXtreme Spacetimes (SXS) collaboration and the LIGO Scientific Collaboration.
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.

I have taught the following courses:
Astronomy 101, an interactive, general introduction to astronomy.
Astronomy 444, “Applications of Gravitation,” a new course for advanced undergraduates that I am piloting, focusing on some applications of general relativity: black holes, gravitational waves, and cosmology.
Physics 211, “Elementary Physics,” an algebra-based introduction to mechanics and thermodynamics.
Physics 211L, “Elementary Physics Laboratory”, the laboratory co-requisite to Physics 211.
Physics 225, “Fundamental Physics,” a calculus-based introduction to mechanics. I have redesigned this course using a flipped classroom, supported in part by the CSU Sustaining Success and Proven Course Resdesign redesign programs.
Physics 300, “Survey of Mathematical Physics”, a course that bridges the under-division and upper-division undergraduate physics major courses, introducing key mathematical tools while emphasizing how to think about math like a physicist.
Physics 330A and 330B, “Electromagnetic Theory I and II”, an upper-division course on electromagnetic theory.
Physics 520, “Analytical Mechanics,” a master’s-level course in classical mechanics and special relativity.
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.
