Mechanisms of bacterial defense andviral counter-defense


We aim to understand the mechanisms that bacteria use to defend themselves from phage infection and counter mechanisms that phages use to subvert bacterial immune systems. Much of the lab focuses on CRISPR systems but we are also interested in other immune pathways. Read more about our research.

Genome engineering

Cas9 Genome Editing
We use Cas9 genome editing technologies to for loss and gain of function studies related to host parasite interactions in humans, plants, and insects. We are also developing new technologies designed to improve surgical repair of defective genes.

Host-parasite interactions

host parasite
We are interested in understanding the co-evolution between hosts and their parasites. Current research focuses on infections by Chlamydia, Ebola, Salmonella, and Helicobacter.
