Hosts, Microbes, Molecular Pharming, and More with Professor Jennifer Geddes-McAlister

On this episode of Translating Proteomics, Parag speaks with Professor Jennifer Geddes-McAlister from the University of Guelph. Professor Geddes-McAlister is an expert at using proteomics to study host-microbe interactions from a systems biology perspective. Her exciting work spans studies of pathogenic fungi all the way to engineering plants to produce pharmaceutics (so-called “molecular pharming"). On top of all that, Professor Geddes-McAlister also founded “Moms in Proteomics” to support and encourage an intentional focus on the inherently unique physical, emotional, and biological commitments of Mothers, and the ensuing balance required to excel within the diverse STEM fields encompassing Mass-Spectrometry-based proteomics.
