Profile

I am a marine geophysicist and a Research Associate with the International Ocean Discovery Project (IODP) and the European Petrophysics Consortium (EPC) at the University of Leicester. As a Petrophysics Staff Scientist, I am responsible for the collection of physical properties and downhole logging data during IODP expeditions on Mission Specific Platforms (MSPs). I am currently working on the operational support for Exp. 386 “Japan Trench Paleoseismology” and Exp. 377 “Arctic Ocean Paleoocenography”. 
Before starting in Leicester in 2019, I worked at the Alfred-Wegener Institute, Helmholtz Center for Polar and Marine Research, where I received my doctorate in cooperation with the University of Bremen (2016) and afterwards coordinated a community-based project on the paleobathymetry of the Southern Ocean.

Research

Additional to my operational role I am focusing my personal research on solid earth - cryosphere - ocean interactions. I am interested in how oceanic gateways and the development of ice sheets shape our ocean currents in the Southern Ocean as well as in the North Atlantic. In 2020 I participated in the IODP Exp. 395 “Reykjanes Ridge: Mantle Convection and Climate” as physical properties and downhole logging science party member. We are aiming to understand how the pulsation of the Iceland mantle plume influences water mass exchange between the North Atlantic and the Northern Seas.

Teaching

I am part of the organizational team of the "ECORD summer school: Down-hole logging for IODP Science" hosted at the University of Leicester. Additionally, I am lecturing on various other IODP/ECORD summer schools such as the "Virtual Drillship experience @marum" at the University of Bremen, Germany and the "PAIS/IODP Antarctic School" at the Gulf Coast Core Repository in College Station, USA.
