Debbie Brock is a recent postdoctoral fellow who was first to discover that Dictyostelium discoideum has the ability to harvest bacteria within the sorus. She received her BS from University of Southern Mississippi in 1976 and her PhD from Rice University officially in May 2012. Upon graduating from college, she worked as a Research Assistant at one of the highest ranking cancer centers in the Unites States, MD Anderson Cancer Center in Houston TX, until 1991. She then took a position as a research assistant at Rice University in Richard Gomer’s lab working with Dictyostelium discoideum where she concentrated on genetic and biochemical factors that influenced group size. In 2005 she began working in the Strassmann/Queller lab, first as a researcher, then as a graduate student. Part of her Ph.D. thesis was published in Nature, entitled Primitive agriculture in a social amoeba. She is currently extending her study of symbiotic interactions between bacteria and D. discoideum and running the lab group. In her spare time, she can be found playing with her granddaughter.
