Research Interests: Bacterial diversity and ecophysiology; Interactions of bacteria with organisms of other trophic levels; Organic carbon transfer through the food web mediated by bacteria; Microbial collaboration and competition. My former projects have mainly centred on the development and diversity of bacteria during phytoplankton blooms. I have studied the ecophysiology of various aquatic phylotypes and the impact of microbial carbon uptake on the aquatic food web. Currently I am involved in a multidisciplinary project evaluating the presents of antibiotic resistant bacteria in the human gut of people with different dietary habits. Therein my part consist of evaluating the bacterial diversity using NGS and relating bacterial phylotypes to potential functions in the gut.
 
I manage the NGS facility of the MEG.
