I am an evolutionary biologist and oceanographer interested in the diversity of marine zooplankton. I want to know: which and how many species live in the open ocean? What processes drive the evolution of marine plankton?

“From the first moment I saw a petridish full of plankton, I knew I wanted to study this incredible diversity and find out how it evolves in the open sea.”
My research is motivated by a fundamental interest in the drivers of marine biodiversity. I want to know how this diversity evolved in an environment that seems to lack any obvious isolating barriers. I am also increasingly worried about our oceans and wonder whether marine organisms will be able to adapt to global change. The open ocean is the largest ecosystem on Earth and of crucial importance for our own well-being. Plankton produces half of the world's oxygen and is at the basis of most marine foodchains, so without it there would not be any fish, whales, seabirds etc.
Currently, my research focuses on planktonic snails as these are particularly sensitive to the effects of ocean acidification. My research team applies a multidisciplinary approach to better understand and predict their potential to adapt to a rapidly changing ocean.
In the spotlight:Evolution of planktonic gastropods
Planktonic gastropods have tremendous potential for the study of long-term marine evolutionary processes because they are the only living animal plankton with a good fossil record. Although most marine gastropods are benthic, two large groups (referred to as 'pteropods' and 'heteropods') have a holoplanktonic lifestyle and represent independent colonizations of the open water column. Planktonic gastropods, and particularly pteropods, have received much attention as bio-indicators to monitor the negative impacts of ocean acidification (OA) on open ocean ecosystems.
