Research Interests

My current and previous research focuses on ecophysiology and cell biology of marine microalgae.

My major areas of research over the last 5 years can be divided into the following research categories: marine microalgal blooms (with special reference to the role of biotic and abiotic factors in harmful algal bloom formation and levels of toxicity); microalgal potential for biotechnology (e.g. biofuel potential, isolation of bioactive compounds, aquaculture feeds); bioluminescence of marine dinoflagellates and the establishment of this endpoint in whole effluent toxicity tests; benthic microalgal community analyses; nutrient physiology with a focus on nutrient utilization of micro- and macroalgae with reference to phytoremediation of nutrients.

Recent and Current Projects Include

  • Toxic microalgae, invasiveness and blooms

  • Microalgal potential for biotechnology

  • Regulation and function of bioluminescence in marine dinoflagellates

  • Ecotoxicology of metals and pesticides using microalgae as test species

  • Seasonal dynamics of tropical marine and freshwater microalgae

  • Nutrient utilization by tropical micro- and macroalgae

Future PhD Directions

  • Cell biology of toxin production in phytoplankton, e.g. Do organic nutrients contribute? Who produces the toxins really?

  • Cell biology of phytoplankton signaling, e.g. What leads to phytoplankton blooms? Are blooms the result of community cross talk?

  • Invasive and toxic microalgae, e.g. Developing phytoplankton surrogates to test the efficiency of ballast water treatment plants.

  • Searching for new tropical phytoplankton strains beneficial to the tropical aquaculture industry and potential for biofuel production.

  • Developing phytoplankton-based screening procedures for the biologically active compounds, e.g. A diatom-based screening assay to evaluate the efficiency of natural anti-fouling compounds.

  • Cell biology of bioluminescent systems, e.g. What turns them on or off? Is bioluminescence a good reporter system for water quality?

  • Cell biology of Golgi protein traffic, e.g. What is the nature of the biological glue molecules of diatoms? What makes diatoms stick or move on? Could the diatom glue provide a mean for the bioremediation of metal pollutants?

  • Tropical phytoplankton taxonomy (marine and freshwater).
