Brent Westbrook


My name is Brent Westbrook, and I am currently a Staff Scientist at the Open Force Field Initiative working on the parameterization of force fields. Previously, I did my PhD in chemistry at the University of Mississippi with Ryan Fortenberry, where I worked on automating anharmonic vibrational spectra calculations and reparameterizing semi-empirical methods. I am exclusively a computational chemist, so I spend more of my time with computers than with chemistry. As a result, I occasionally have interesting things to share about computers here or on my YouTube channel.

I was also a general chemistry Supplemental Instruction leader for four semesters and wrote many worksheets during that time, so I also have them accessible here.
