Kia ora 👋

I’m a Postdoctoral Fellow in the Microbiome Manipulation Lab at UTSC.

I’m passionate about understanding microbial evolution and niche adaptation - both in the field and under controlled or experimental settings.

My current research seeks to examine tradeoffs between the production, storage, and in-soil application of candidate probiotics for agriculture.

My doctoral research used the kiwifruit pathogen Pseudomonas syringae pv. actinidiae to understand how plant pathogens evolve during incursions. Using this horticulturally-relevant pathosystem, we examined effector requirements, redundancies, and repertoire refinement across different hosts, using complementary approaches of orchard-based genome biosurveillance and knockout strain competition!
