Scholarly Activities

As a dedicated educator, I enthusiastically lead large general chemistry classes (CHEM 151 and CHEM 152) in collaborative learning spaces. I employ active learning techniques and evidence-based teaching practices to promote learning in my classroom. Inclusivity is paramount, and I proactively foster an environment that promotes diversity, equity, inclusion, and respect (DEIR) to nurture the potential of every learner. Additionally, I actively collaborate with Professor Michael F. Brown on rhodopsin research, guiding and mentoring graduate, undergraduate, and high school students in scientific exploration.

Research Description

Our research endeavors revolve around unraveling the intricacies of G-protein coupled receptor (GPCR) activation, with a particular focus on utilizing rhodopsin as the model receptor. GPCRs play a pivotal role in regulating numerous physiological functions and serve as targets for a wide range of pharmaceuticals. Thus, comprehending the process of GPCR activation not only deepens our understanding of diseases but also aids in the development of more effective drugs.

To shed light on this fascinating area of study, we employ a combination of optical spectroscopy, neutron scattering, and ultra-fast X-ray scattering techniques. These experimental methods provide valuable insights into the structural and dynamical changes of rhodopsin during its activation process. Complementing experimental findings, we harness the potential of computational modeling, including molecular dynamics and quantum mechanical simulations. This powerful fusion enhances our understanding of rhodopsin activation at a molecular level.

Our ultimate quest is to decipher the molecular mechanisms governing GPCR activation, contributing to the advancement of scientific knowledge. By combining the experimentation with computational modeling, I aim to pave the way for transformative therapeutic interventions.
