I am interested in the dynamics, ventilation and the oxygen budget of oxygen minimum zones in the open ocean. My goal is to understand and quantify physical and biogeochemical sources, which set the mean state as well as changes in the oxygen distribution in these regimes. For my analyses, I use measurement data from different observational platforms combined with simulations from physical-biogeochemical ocean models.
