Principle Investigator

Dr. Dustin Little

Dustin received his BSc in Biochemistry in 2008 from the University of Waterloo. He then worked for one year in the food science industry before completing his PhD in Biochemistry in 2015 at the University of Toronto under the supervision of Dr. Lynne Howell. From 2015 to 2019, Dustin was a postdoctoral fellow in the Department of Biochemistry and Biomedical Sciences at McMaster University in the lab of Dr. Brian Coombes. In 2020 he joined Ryerson University establishing his lab in the Department of Chemistry and Biology.

Postdoctoral Fellows

Dr. Liangcheng Henry Xu

Henry completed his PhD in Biomedical Engineering from the University of Toronto and joined the Little Lab in October of 2020 as a postdoctoral fellow. His project focuses on developing a functional immunoassay for measuring SARS-CoV-2 neutralizing antibodies and integration into a microfluidic device. Outside the lab Henry enjoys hiking, playing video games, and catching up on Friends episodes on Netflix.

Graduate Students

Sarah Birstonas

Sarah joined the Little Lab in the fall of 2020 as a PhD student in the Molecular Sciences program at Ryerson. Her project focuses on the post-translational regulation of the type III secretion system and how it affects bacterial virulence and infection. Sarah's interests include reading Sci-Fi/Fantasy novels, cooking, and cycling around The 6.

Thomas Esmond

Thomas joined the Little Lab in the summer of 2020 and then started his MSc in the Molecular Sciences program at Ryerson in the fall of 2020. His project focuses on the post-translational regulation of O-antigen biosynthesis and how these modifications affect bacterial virulence and physiology. Outside the lab, Thomas is involved with Ryerson Tabletop Gamers in Science, enjoys video games, and plays the guitar.

Michelle Chevtchouk

Michelle joined the Little Lab in the fall of 2020 as an MSc in the Molecular Sciences program at Ryerson. Her project focuses on bacterial tyrosine phosphorylation systems and how it affects bacterial physiology.
