Dr. Harris studies atomic collisions, whic provide key insights into one of the most fundamental forces of nature – the Coulomb force. The study of atomic collisions is primarily used to understand the dynamics of charged particle interactions, but is vital to other areas of physics, such as plasma physics, astrophysics, and biophysics.
One focus of our group’s work is the study atomic collisions using state-of-the-art theoretical and computational methods. We specialize in four-body scattering problems, such as simultaneous excitation-ionization and charge transfer collisions. The second area of our group’s research is the study of networks in biological systems. We are currently studying the role of stochasticity in gene regulatory networks, as well as using artificial neural networks to study memory in the brain.
