Bryan Lynn Finding the Tipping Point Inspiration Dissemination

What do we know about cooperation? Can we quantify the tipping point? This week’s guest, Bryan Lynn, a second-year PhD student co-advised by Dr. Patrick De Leenheer in the Department of Integrative Biology and Martin Schuster in Microbiology studies the evolution of cooperation. To do this, Bryan scales his work way down to microorganism level. Evolutionary theory has been largely based on the Darwinian premise of the survival of the fittest, but Bryan’s research is challenging this – not cooperating makes you more fit as an individual, but is that best for the group as a whole? Using the bacteria Psuedomonas aeruginosa as a model organism, Bryan is able to manipulate the behavior of the bacteria and study what happens in a chemostat system – a device which allows the bacteria to grow continuously with a constant input of a food source and output of the mixed solution - making it an excellent metaphor for life. For example, Bryan mutates some of the bacteria to be so-called “cheaters,” as they do not make an enzyme and thus do not expend energy but reap all the benefits as the non-cheater bacteria. Using mathematical models, Bryan is able to simulate different conditions and put a number to the tipping point where the community is no longer able to persist in a steady state. Listen to learn more about Bryan’s math biology research, non-traditional journey to graduate school, and LGBT+ activism. Hosted by Lauri Lutes and Chelsea Behymer.
