Katy D. Heath is a Professor of Plant Biology and Affiliate Professor in Microbiology at the University of Illinois Urbana-Champaign (UIUC). She leads the Plant Biology department and is affiliated with the Carl R. Woese Institute for Genomic Biology. Her research focuses on the evolution of mutualisms, particularly plant-microbe interactions such as legume-rhizobium symbiosis, emphasizing genetic and ecological factors influencing symbiotic stability and adaptation. She investigates how environmental pressures (e.g., global change) shape mutualistic relationships and microbial community dynamics. Education: B.S. (2000) and Ph.D. (2007) from the University of Illinois and University of Minnesota, respectively, followed by postdoctoral work at the University of Toronto (2007–2009). Research Interests: Symbiosis evolution, microbial genetics, plasmid transmission dynamics, and the impacts of agricultural practices on rhizobia populations. She studies diverse systems, including Medicago-Sinorhizobium, soybean-Bradyrhizobium, and invasive legume-rhizobium interactions. Recent publications (2020–2025) highlight studies on endophyte impacts on soybean yield, rhizobia diversity under conventional farming, and genomic analyses of symbiotic coevolution. Her work integrates molecular biology, quantitative genetics, and ecology. Grants & Collaborations: Lead PI on a $12.5M NSF Biology Integration Institute (Genomics and Eco-evolution of Multi-scale Symbiosis). Her team includes collaborations with institutions like Indiana University and the University of Chicago. Labs & Teams: Heath Lab focuses on symbiosis research, with active projects on microbiome dynamics, plasmid-host coevolution, and community outreach (e.g., Boys and Girls Club collaborations). Recent lab highlights include student graduations (e.g., Ivan Sosa Marquez, Chase) and awards like the John R. Laughnan Award in Plant Biology.
