Dr. Jennifer Geddes-McAlister

• BSc (co-op) – University of Lethbridge, Biological Sciences
• MSc – University of Lethbridge, Biological Sciences
• PhD – University of British Columbia, Microbiology and Immunology
• Postdoctoral Fellow – Max Planck Institute of Biochemistry, Proteomics and Signal Transduction

We are interested in characterizing the mechanisms of pathogenesis, adaptation, and survival in fungal and bacterial microbes from a systems biology perspective through mass spectrometry-based quantitative proteomics. Specifically, research in the lab centres around the following areas:

1. Differential patterns of pathogenic regulation between microbial species;
2. Systems biology to elucidate microbial proteome dynamics and interactions;
3. Mechanistic characterization of pathogenic proteins; and
4. Mass spectrometry-based proteomics for drug discovery and repurposing.

Our long-term goals emphasize the utilization of mass spectrometry-based proteomics to fundamentally understand differential microbial adaptation and survival strategies and to integrate a novel systems biology platform for investigation of diverse biological systems, defining functional mechanisms of cellular regulation and pathogenesis.

Interested students and post-doctoral fellows are encouraged to contact me to learn more about new and exciting opportunities.
