Lewis Research Group

Infectious diseases account for the majority of deaths in developing countries and are among the ten leading causes of mortality in Canada. The emergence of diverse drug resistant pathogens has made finding new antimicrobial therapies both a Canadian and global health priority. The Lewis research group investigates the connection between metabolic adaptation and virulence of human pathogens. The ultimate goal of this research is to develop new diagnostic methods to identify high risk patients and novel antimicrobial therapies to control infections. One of the key challenges my laboratory faces is unraveling the complex host-pathogen metabolic dynamics that occur during infections. To address this challenge, we use state-of-the-art mass spectrometry (MS) and nuclear magnetic resonance (NMR) technology to comprehensively quantify the flow of molecules between pathogens and their hosts. This metabolomics approach is a powerful strategy for connecting metabolic phenomena with specific genes and is essential for understanding the metabolic determinants of virulence.


The Lewis research group specializes in metabolic analysis of human pathogens. Our facilities include two separate biosafety-level two laboratories dedicated to eukaryotic and prokaryotic pathogens, and a state-of-the-art mass spectrometry laboratory.
