Dr. Hanna Koch has been given many nicknames, including "coral matchmaker" and "coral fertility doctor." She's conducting managed breeding efforts with threatened coral species, part of the coral reef science and restoration mission of Mote Marine Laboratory scientists in the Florida Keys. In this episode of "Two Sea Fans," Koch explains where coral babies come from, how scientists are helping native corals reproduce sexually in a controlled setting, and why sexual reproduction is so important for providing fresh genetics to coral populations that are struggling in the wild. Tune in and add some science to your Valentine's Day! Koch is a Postdoctoral Research Fellow with the German Research Foundation and Visiting Research Scientist at Mote’s Elizabeth Moore International Center for Coral Reef Research & Restoration (IC2R3).
