BIOLOGICAL OCEANOGRAPHER at Harbor Branch Oceanographic Institution (HBOI), in the Marine Science, Aquaculture and Environmental Divisions, including postdoctoral research. HBOI was founded in 1971 by J. Seward Johnson, Sr. in collaboration with Edwin A. Link as a non-profit research organization. In December 2007, HBOI was transferred to FAU and took its current name: Harbor Branch Oceanographic Institute at Florida Atlantic University, operated by FAU.

PROJECTS as RESERACH SCIENTIST (PI and Co-PI) 1994-1996 & POSTDOCTORAL RESEARCH (1991-1993):

• Effect of oceanographic parameters and environmental changes on fish reproduction, recruitment and early life stages of subtropical & tropical fish species. Reserach incl. monitoring of oceanographic parameters, quantitative ichthyoplankton sampling,  fish sound production and recording, and fish larviculture experiments.

• Oceanographic Parameters associated with Spawning, Larval Dispersal and Early Life History of the Spotted Seatrout, Cynoscion nebulosus. Multidisciplinary oceanographic field research. Funding by the Department of Environmental Protection and Harbor Branch Link Foundation.

• Reproduction & recruitment studies of subtropical larval and juvenile fish (Pomacentridae and Sparidae). Funding by Harbor Branch Link Foundation.

• Participation in Marine Environmental Research Program studying the reproductive biology, early life histories, ecology and conservation biology of estuarine and reef fish species, funded by the FL Dept. of Environmental Protection.

• Biophysical oceanographic conditions associated with fish recruitment. Participation in oceanographic expeditions to the Atlantic and Bahamas. Participation in Harbor Branch’s oceanographic expeditions on RV SEWARD JOHNSON with submersible dives studying benthic communities in the Bahamas Archipelago. In collaboration with Smithsonian Institution's Marine Station.

• Participation in biophysical oceanographic research expedition to the Sargasso Sea aboard the RV CAPE HATTERAS studying  unique pelagic creatures drifting in the tropical Gulf Stream - part of the "Salp Migration Project". Research included vertical migration studies of oceanic pelagic organisms (from the epipelagic to the mesopelagic zones) and their oceanographic environment. Blue-water research cruise in North Atlantic studying deep water fish ecology. In collaboration with Woods Hole Oceanographic Institute.

• Ocean conservation and spiny lobster stock enhancement research funded by the Florida Fish and Wildlife Conservation Commission (FWC). Larviculture experiments at Florida Institute of Technology's Vero Beach Marine Laboratory.

• Development of Culture Techniques for Tropical Marine Ornamental Reef Finfish to replenish tropical coral reef ecosystems. For Display at the Living Seas of Walt Disney World’s EPCOT Center, Orlando, Florida. Funding by Walt Disney World.

• Wetland Impoundment Management, Accessibility and Influence on Stock Enhancement, Survival and Migration of the Striped Mullet, Mugil cephalus. Funding by the Department of Environmental Protection.

• Assessment of Fish Deformities as Influenced by Degraded Indian River Lagoon Water Quality. Management of a multidisciplinary oceanographic field study. Funding by the Day Cancer Research Foundation, Inc.

• Resident and Caged Organism Mercury Bioaccumulation Studies at the Everglades Nutrient Removal Project. Management of research including aging of adult largemouth bass - in collaboration with and performed at Duke University's Beaufort Marine Laboratory in Beaufort, NC. Funded by the South Florida Water Management District.

• Study of the effects of cruising vessel speeds on the behavior of marine mammals and birds of the German Wadden Sea. Management of research and preparation of final report. Funding by the Department of Limnological Ecology and Hallig and Island Shipping Company, Germany.

• Assistant Professor teaching annual graduate courses in Subtropical Fish Ecology and Tropical Aquaculture.
