SUMMARY:Diffusion-limited Mutualism in Microbes
DESCRIPTION:Featuring Rajita Menon\n\nPart of the Preliminary Oral Exam.\n\
	nExamining Committee:  Kiril Korolev\, Pankaj Mehta\, Shyam Erramilli and K
	evin Black\n\nAbstract:\nMicrobes cooperate by swapping diffusive metabolit
	es to form robust and fully functional societies. Contrary to intuition fro
	m game theory\, we find that metabolite diffusivity tends to inhibit stable
	 microbial mutualism.  Increasing public goods diffusivity beyond a critica
	l point completely destroys coexistence\, leading species extinction via a 
	nonequilibrium phase transition. Analytical results for the critical diffus
	ivity and typical domain sizes are computed based how public good diffusivi
	ty renormalizes the strength of selection and thus should be applicable to 
	a variety of more complex models. In addition\, fitness nonlinearities supp
	ress mutualism and favor the species producing slower nutrients.\n\n![Rajit
