Coral Health & Disease

Dr. Grace Klinges

Postdoctoral Research Fellow

Dr. Klinges joined the Coral Health & Disease Program at IC2R3 in Fall 2021 after completing her PhD in Microbiology at Oregon State University. Her research there centered around the discovery and characterization of a prolific bacterial parasite of Caribbean acroporid corals that contributes to disease susceptibility in these species. Her research questions require the use of diverse methods including qPCR, microbial sequencing and genome assembly, and coral health assessments. At Mote, Dr. Klinges will continue to study the response of this parasite in the genus Aquarickettsia to environmental changes affecting coral reefs, and will conduct other field- and lab-based research on the role of bacteria in stony coral diseases.
