Turn the most powerful discoveries about health into products that change your life



The Gut Microbiome
Creates a balance of helpful and harmful molecules

This Balance Shifts
Emphasizes harmful metabolites as you get older and eat the modern diet

Dr. Daniel Winer is an MD turned researcher who has been a leader in immunology research for two decades. He primarily studies immune cells in the gut, which are a distinct immune cell population. Winer led the research which illuminated the true extent of these immune cells’ influence not just in the gut, but throughout the body, and his research now shapes approaches to cancer, diabetes, and neurological disease. Winer is presently an Associate Professor at the Buck Institute for Research on Aging and an Affiliate Professor at University of Toronto. His education includes a medical degree from the University of Ottawa and a post-doctorate at Stanford University.

Nicholas Tubach is a life sciences entrepreneur who has founded three companies to address chronic diseases of aging which he says unfairly burden the second half of people’s lives. Tubach studied cell biology at UC Berkeley, but his education was primarily self-motivated, learning from scientific advisors and business executives who became his cofounders at Synap Biotech, Repoxegen Therapeutics, and Propion Inc.
