Research Interests:

My current research focuses on the parathyroid hormone receptor (PTHR), a G protein-coupled receptor critical to bone and kidney health. I am using computational and structural (e.g., NMR, EM) methods to understand the mechanisms of ligand binding, PTHR activation, and signaling.
