The focus of my research is the development and analysis of numerical relativity simulations, particularly in the context of gravitational wave detections. An important part of that has been assessing the readiness of current numerical relativity codes for the challenges that will come with LISA and third-generation ground-based detectors, both in terms of accuracy and parameter coverage. Most recently, I have also become involved with using numerical relativity to explore beyond GR theories. I conduct this research with Dr. Helvi Witek as a postdoc at the University of Illinois Urbana-Champaign. I am also involved with the LIGO Scientific Collaboration and the LISA Consortium.
