I’m an Assistant Research Scientist at the Institute for Physical Science & Technology and currently serving as the Faculty Director of the Quantum Computing MS Program at the University of Maryland. Here, you’ll find information about my research and thoughts.
My research is about numerical computations of waves in infinite domains. Much of my work concerns gravitational waves, but I also apply relativistic methods to nonrelativistic problems. Lately, I’ve been interested in hyperbolic geometry as it appears in many areas of science, such as special relativity, black holes, quantum gravity, machine learning, biology, number theory, and oceanography.
I regard science administration as the highest form of public service. Through my teaching and leadership, I connect graduate education, student mentoring, and scientific communities. I also help organize conferences and workshops, including the Quantum Biotechnology Conference and Envisioning Future of AI and Chemistry.
