Research Interests

I am interested in nuclear theory. My work focuses on accurate computations of atomic nuclei and their properties. Using Hamiltoians from effective field theories of quantum chromodynamics, the fundamental theory of the strong force, allows us to make systematically improvable approximations in our calculations. The group uses supercomputers in this task and, more recently, also studies how to perform such computations on quantum computers. For research and teaching we launched NuLattice, a Python software package for computations of atomic nuclei on spatial lattices.
