I’m a PhD student in Biophysics at Harvard, where I am interested in the structure, function and evolution of proteins. I am currently working with Rachelle Gaudet and Debora Marks on learning the sequence determinants of substrate selectivity in a model bacterial transporter using deep mutagenesis coupled with evolutionary sequence modeling. My broader goal is to be a small part of the huge project to link our understanding of the “jigglings and wigglings of atoms” to the scale of evolution over billions of years.
