​As a plankton biologist my primary focus lies in the field of microphytoplankton taxonomy. I am also interested in studying the interaction between phytoplankton and zooplankton. Impact of UV radiation as well as increasing global temperature on the survival of planktonic organisms were also focused.

Research Interest

Marine ecology, microphytoplankton taxonomy, plankton biology
