Research Interests

My current research focus is on the mathematical and computational modeling of infectious disease. In particular, I like working with experimental data sets to understand virus infection dynamics. I also have experience and interests in statistical physics, astrophysics, nonlinear dynamics and quantum physics. As of 2020, I am shifting toward work on gravity and gravitational waves.
