Tasks/ Research Area:

I am working on discrete and continuous optimization algorithms and their parallelization. My current position is within the research platforms of the excellence cluster 'The Future Ocean'. Recently, my focus is on the assessment of biogeochemical  ocean models via parameter optimization (model calibration) and associated quality proofs.
