I am an integrative marine ecophysiologist interested in how marine fish and invertebrates have adjusted their physiology to the specific environments during their evolutionary adaptation.
While these adaptations usually provide them with ideal capacities to prosper in their habitats, they do not always cover for environmental and climate change – specifically not in those habitats that have been very stable over evolutionary timescales.
The focus of my research therefore lies on the physiological adaptation and acclimatization capacities of polar fish and cephalopods towards climate change, namely ocean acidification, warming, and deoxygenation.
Mostly based on laboratory experiments on the aerobic energy metabolism, I work on different levels of biological organization from the molecular level to mitochondria and the cardio-vascular system, also including whole animal exercise and cutting edge field-physiology applications.
My research also involves ship- and land-based expeditions to both the Arctic and Antarctic and I have led several environmental monitoring cruises to Svalbard to document changing ecosystems.
I have played a lead role in the German ocean acidification research program BIOACID (2009-2018) and also regularly contribute to scientific outreach and information of policy and decision makers, e.g. as a contributing author for the IPCC 6th Assessment Report.
