I'm Charles, a scientist in the Safronova group at the University of Delaware. My research focuses on developing high-precision computational methods for relativistic atomic structure calculations. These methods play a key role in next-generation technologies such as ultra-accurate atomic clocks and in searches for new physics beyond the Standard Model. I am also contributing to the development of the Portal for High-Precision Atomic Data and Computation, which provides state-of-the-art atomic data to the broader scientific community.

I received my Ph.D. in Theoretical Atomic Physics from the University of Delaware, where I created the first versions of pCI, a parallel relativistic atomic structure code package based on the configuration interaction (CI) method. This work included modernizing legacy Fortran 77 codes, implementing high-performance computing techniques, and applying them to large-scale CI calculations of complex atoms and ions relevant to precision experiments. You can find a copy of my thesis here.
