Sandra Brooke earned her Bachelors in Biological Sciences from Essex University in England and spent a few years working in mosquito control before discovering marine biology. Her Masters degree (1996) was from the Virginian Institute of Marine Biology in Virginia, and her PhD (2002) was a joint venture between the University of Southampton in England and Harbor Branch Oceanographic Institution in Florida. Her dissertation research focused on the reproduction of a deepwater stony coral called Oculina varicosa, which forms large fragile reef systems at 100m depth along the shelf edge of Florida’s Atlantic coast. Her research described the seasonal cycles of egg production (gametogenesis), number of eggs produced (fecundity), and the development and biology of the coral larvae. Sandra is currently working as a Research Associate at the Oregon Institute of Marine Biology where she is involved in several deepwater coral projects including a National Marine Fisheries Service Alaska project to survey deepwater coral systems off the Aleutian Islands, reproduction of Lophelia pertusa in the Norwegian Fjords with the Trondheim Biological station in Norway, and habitat characterization of deepwater coral habitats in the Gulf of Mexico.
