Dr. Kim Beach Ritchie is Senior Scientist and manager of the Marine Microbiology program at Mote Marine Laboratory. She has been studying microbes associated with corals and other coral reef organisms for over 20 years. Dr. Ritchie began her work at Mote on coral microbiology, coral diseases and coral host resistance in 2004. Currently she studies host-microbe interactions and is particularly interested in the role of beneficial microbes in corals and other marine organisms.
