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. Dive into this episode to:Learn why it’s critical to study hosts, pathogens, and molecular pharming from a systems point of viewDiscover what Professor Geddes-McAlister is excited about for the upcoming Human Proteome Organization (HUPO) conferenceFind out what “Moms in Proteomics” has planned for HUPOChapters00:00 - Intro01:39 - Professor Geddes-McAlister's initial interest in host-microbe interactions06:13 - Why it's important to study host-microbe interactions08:10 - Pathogens vs helpful microbes10:06 - Thinking about microbes through the lens of "One Health" 14:34 - Why Professor Geddes-McAlister works primarily in proteomics as opposed to other omes19:44 - Professor Geddes-McAlister's favorite thing that she's learned from the proteome and couldn't learn from the other omes24:56 - Molecular pharming29:35 - The need for accessibility in proteomics34:09 - The need for all-in-one workflows in proteomics36:08 - HUPO 202539:56 - Moms in Proteomics42:36 - The future of proteomics43:59 - OutroResourcesGeddes et al., 2015.
