Research Interest: I completed my PhD at Dalhousie University in Halifax, Canada, where I investigated the commensal oral bacterium Streptococcus gordonii. In 2016 I joined Raphael Valdivia’s lab where I am working with another commensal organism, Akkermansia muciniphila. A. muciniphila is a recently discovered inhabitant of the gut microbiota that is associated with metabolic health. The aim of my project is to develop genetic tools to better understand the basic mechanisms of A. muciniphila colonization and how it benefits its host.

Personal Interests: I spend my free time watching SpongeBob SquarePants and Dr. Who, playing Stars Wars video games, building Legos, checking out comic book stores, and hanging out with my 10 year old son.
