Alumni and Former Staff

Research Specialist​

Research Interests

​As a plankton biologist Reny's primary focus lies in the field of microphytoplankton taxonomy. Reny is 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.
