The primary focus of my research is molecular ecology/functional genomics of dinoflagellates and other marine phytoplankton (microalgae). Current research can be summarized as: 1) gene regulation in dinoflagellates; 2) nutrient (especially P) physiology in phytoplankton; 3) proton-pump rhodopsin in dinoflagellates as potential solar energy harnessing mechanism; 4) phylogeny and evolution of dinoflagellates; 5) ecology of harmful algae; and 6) DNA barcoding and phytoplankton biodiversity.

The second focus of my research is symbioses (e.g. coral-dinoflagellate, protist-alga). We take genomic approach to study how host/symbiont specificity (or plasticity) and symbiosis is regulated, and to provide insights into how coral bleaching is triggered and how bleached corals may be restored.

In addition, we use molecular techniques to study trophic relationships (food web structure) in incubation-free fashion (in situ). For instance, we have developed PCR-based techniques for analyses of diets of wild-caught copepods, which have revealed surprising diet compositions.
