Scientific Interests

My present work focuses on biogeochemical investigations related to fluid and gaseous fluxes at cold seeps and gas hydrate bearing sediments on continental margins. As a biologist my interest lies in the interactions between geochemistry and chemosynthetic communities in these special environments.

I am involved in several interdisciplinary national and international projects as a principal investigator and like to work in close cooperation with engineers and technicians to design, construct and use complex video-guided instruments. These instruments are designed to perform in situ measurements at cold seeps and hydrothermal vents to understand the control parameters (i.e. tides, microseismicity, bioirrigation) and the importance of these fluid flow phenomena on a wider scale.
