Raymond Huynh – MSc

On Oct 8th, 2021, Raymond defended his MSc work on heterogeneity in the pmrD gene in Shigella and E. coli. Raymond has been an integral part of the team since joining as an undergraduate in 2018. He initiated all of the Shigella work that is currently happening in the lab and he was a fantastic team player. He was responsible for training of many other undergraduate trainees in the lab and his. We will certainly miss his calm presence in the lab, but he won’t be far away – he’s started a new position at UHN and we hope he’ll continue to pop by the lab from time to time… he’s always welcome here!

Adam Khan – MSc

On Jul 31, 2019, Adam Khan successfully defended his MSc on heterogeneity in two-component signaling responses in clinical isolates of IBD-associated E. coli. Congratulations Adam!

McPhee lab at CSM 2019

Youn Hee, Adam and Joe all recently attended the Canadian Society for Microbiologists meeting in Sherbrooke, Quebec. In addition to excellent poutine, craft beer, and some thrilling basketball games, some truly excellent science was also shared by all. Adam received a travel award from the CSM Executive to present his work and Youn Hee gave an update of her work on omptin regulation in Escherichia coli.

Michael Renouf and Youn Hee Cho publish IBD-associated E. coli review

We are excited to see this in print! This work describes the broad phenotypic conservation of E. coli found in IBD patients and argues that a focus on genetic characterization may miss numerous phenotypes that are not readily predicted or predictable. We hope that some of the ideas here gain traction and provoke new ways of thinking about how intestinal microbes might drive changes in the host that are associated with IBD.


Michael Renouf – MSc

Michael recently defended his MSc work entitled, “Interactions between adherent-invasive Escherichia coli and host macrophages: a virulence phenotype”. Michael is now working as a clinical data management specialist and we wish him all the best in his future career.

McPhee lab at CSM2018

The Canadian Society of Microbiologists AGM was held from June 20-23 at the University of Manitoba. Joe McPhee presented a talk highlighting recent work by Youn Hee Cho and Riasad Fadle Aziz on the role of the PhoPQ system in the regulation of omptin activity, while Michael Renouf presented his work describing how AIEC can alter macrophage behaviour while Youn Hee Cho presented her work on phenotypic diversity in IBD-associated E. coli.

Undergraduate thesis defenses

McPhee lab at Ryerson CAB Undergraduate Research Symposium

The Department of Chemistry and Biology hosted an undergraduate research symposium where McPhee lab undergraduate students Rebecca Cabral Diaz, Riasad Fadle Aziz, Ashuka Kayastha, Najih Ismail and Shion Song presented their 4th year thesis work. Thanks to Michael Renouf for his excellent work chairing the session. Congratulations to everyone!

McPhee lab at CSM 2017

From June 20-23, members of the McPhee lab attended the Canadian Society of Microbiologists Annual General Meeting in Waterloo, Ontario. Youn Hee presented a talk on her project related to host-defense peptide resistance in inflammatory bowel disease-associated Escherichia coli while Michael and Mario gave poster updates on their work as well. The conference was a lot of fun and the group even managed to sneak some work in around the edges.
