My research is primarily focused on the lipid organization of cellular membranes and their perturbation by small molecules. I am interested in membrane protein functional regulation by their lipid environment and how drugs/amphiphiles can change bilayer properties and, therefore, indirectly alter protein function. To address these questions I have used a combination of experimental and computational methods, utilizing atomistic, coarse-grained and multiscale molecular dynamics methods. Recently, I have predominantly focused on the coarse-grained Martini model: improving the model, contributing to membrane building tools, extending the Martini lipidome, modeling biologically realistic membrane compositions, and modeling biologically realistic membrane compositions and advancing multiscale methodologies.
