Ricky Sexton

Ricky graduated from ASU with a doctorate in physics in December of 2023. He did a research rotation project in Fall 2017, where he was working on a computational method for performing pKa calculations, namely our open source propkatraj method. He has since done work on small molecule parameterization for CFTR channel-blockers and the effects of external electric fields on EGFR. He has also investigated membrane properties in molecular dynamics (MD) simulations. His main work has been investigating GPCR-cholesterol interactions using coarse-grained MD and developed a Bayesian framework to analyze the MD data. He would like to better understand how the lipid environment effects protein signaling/transport and build models that can explain the behavior.
