My area of expertise is computational modeling and molecular dynamics simulations. For more than two decades my laboratory’s research has contributed to the understanding of the structure activity relationship (SAR) and the mechanisms of action of many biomedically important proteins, in particular the brain cannabinoid (CB1) receptor, with the overall goal of contributing to the development of therapeutic agents. Currently, my major research focus is upon understanding CB1 receptor conformational changes by allosteric binding, which may alter its pharmacological profile.

Since I strongly support undergraduate student involvement in research (see below), any student who has a passion or curiosity about biomedical research, please contact me!

...You provided us with a great opportunity to understand what it entails to craft a well written manuscript, as well as teaching us about your area of interest...(Alvaro Cortez)

...It definitely was the highlight of my undergraduate studies. I learnt a lot about publishing scientific journals, the format and got to see firsthand the execution of a great body of scientific work. I enjoyed working on this with you all. Thank you for the opportunity to be a part of this...(Arianna Fisher)
