NSF/NIEHS Greater Caribbean Center for Ciguatera Research NSF 1841811

The Greater Caribbean Center for Ciguatera Research (GCCCR) is a five-year, multi-institutional center that includes three interrelated research projects:
1) the role of climate change in geographic and temporal expansion of CFP;
2) toxic metabolite production by Gambierdiscus, and their biotransformation in food webs;
3) the genotoxicity and impactsof toxins on cellular metabolism.

ECOHAB 17/18: LIfe and Death of a Karenia bloom, NOAA NA18NOS4780168

This project combines modeling with physiological and genomic monitoring of Karenia blooms to understand what drives blooms in the eastern Gulf of Mexico. With Co-PIs Darren Henrichs and Lisa Campbell, Texas A&M University.

PIRE: Advancing Global Strategies and Understanding on the Origin of Ciguatera Fish Poisoning in Tropical Oceans, NSF 1743802.

We will be comparing reef sites around the world to better understand the toxic compounds produced by the epiphyte microalgae in these environments, and their fate in the food chain.
