Host Parag Mallick chats with Professor Afshin Beheshti who is a Professor of Surgery, Director of the Center for Space Biomedicine, and Associate Director of the McGowan Institute for Regenerative Medicine at the University of Pittsburgh. In addition, Professor Beheshti has a visiting researcher appointment at the Broad Institute of MIT and Harvard and is president of two non-profits – the COVID-19 International Research Team and Kwaai. The latter aims to democratize access to artificial intelligence through the design, construction, and maintenance of a free personal AI called Kwaai.

Professor Beheshti’s research covers a range of topics focused on how circulating mirco RNAs and mitochondria impact health, but this conversation focuses primarily on Professor Beheshti’s work advancing our understanding of how spaceflight impacts biology. We cover:

1. How research on spaceflight and biology is done
2. Gaps that remain in our understanding of spaceflight and biology
3. Omics studies of spaceflight and biology
4. How studying spaceflight and biology enhances our understanding of human health more broadly

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 view
• Discover what Professor Geddes-McAlister is excited about for the upcoming Human Proteome Organization (HUPO) conference
