RESEARCH INTERESTS

As a marine biologist with broad scientific background
I enjoy working as sssociate scientist for the Bremen International Graduate School for Marine Sciences (GLOMAR).

My general curiosity about "how does the ocean function?" leads to a broad field of research interests covering:

Phytoplankton photophysiology,

Ecological impacts on marine photosynthesis
(bottom up by light/ nutrients and top down by grazing )

Implications of primary poduction processes for marine/coastal carbon dynamics

Currently, I am working with Christian Winter (MARUM) on coastal ecosystem modelling using DELFT3D WAQ with respect to phytoplankton dynamics and their response to changing light and nutrient conditions.
