Dr. Hanna R. Koch

Coral Reproduction Staff Scientist

Dr. Koch joined the Mote team in 2018 as a Visiting Research Scientist with the German Research Foundation to integrate assisted coral sexual reproduction into Mote's ongoing coral reef research and restoration framework. In 2020, Dr. Koch became a Mote Postdoctoral Research Fellow with the Coral Reef Restoration Program at Mote's Elizabeth Moore International Center for Coral Reef Research & Restoration in the FL Keys to continue her research on coral sexual propagation, assisted evolution and coral reef restoration.
