Biography

Mentor: Michael Lerch, PhD
Year Entered MCW: 2019
Previous Education: BS, Physics, Marquette University, 2018

Research Interests

The Lerch Lab studies the molecular mechanisms of G-protein-coupled receptor (GPCR) signaling, with a long-term goal of improving structure-based drug discovery. In my projects, I focus on two post-translational modifications of the β2-adrenergic receptor (β2AR), palmitoylation and glycosylation. This receptor regulates cardiovascular function and is an important drug target for a variety of diseases including asthma and heart failure. I am interested in the effect of palmitoylation and glycosylation on the structure and dynamics of β2AR, which I study using a combination of techniques including variable-pressure continuous-wave and pulsed electron paramagnetic resonance (EPR), mass spectrometry, and functional assays. Additionally, I am interested in developing methods for modeling protein structure and technology to increase throughput for EPR experiments used in our lab and others.
