Research
Our lab focuses on understanding the molecular mechanisms of mutations called gene amplifications and copy number variations (CNVs). Many important biological phenomena, including cancer, infectious diseases, and bioremediation, depend on these mutations to evolve rapidly to their changing environments. Still, the underlying molecular mechanisms remain unclear for all organisms. Our lab aims to unravel these central mysteries along with developing various CNV-related applications.

In order to study gene amplifications and copy number variations, our lab utilizes some of the most genetically tractable organisms: bacteria such as E. coli, Salmonella, and Acinetobacter baylyi. The projects are accessible to undergraduate and Master’s students. Students are trained in important multidisciplinary areas that bridge classical and modern genetics with microbiology, molecular biology, experimental evolution, statistics, and computation.
