Subject: Mathematics

Sergio Bacallado is a lecturer in the Department of Pure Mathematics and Mathematical Statistics and a Fellow in Mathematics at Magdalene.

He completed undergraduate degrees in Mathematics and Chemistry from the Massachusetts Institute of Technology and a PhD in Structural Biology from Stanford University, where he was also Stein Fellow in the Department of Statistics. His research deals with Bayesian methodology, with an emphasis on nonparametric inference, and its application to biological data, such as molecular dynamics simulations and genomic data from human microbiome studies.
