As an environmental physiologist, I am highly interested in the phenotypic plasticity and acclimation/adaptation capacity of marine invertebrates (crustaceans) and vertebrates (teleosts) to a “future ocean scenario” as predicted by climate change experts. Challenging animals with elevated pCO2 and the resulting drop in seawater pH (hypercapnia/ocean acidification) as well as changes in other abiotic parameters like high environmental ammonia, allows me to discover relevant underlying principles that help to ensure the animals’ performance. Particularly, I am interested in the linkage of acid-base homeostasis with the regulation of ammonia, the major waste product of protein metabolism.

For my research, I aspire an integrative approach in an environmental relevant context - from the whole living animal and/or isolated tissues to the underlying genetic mechanisms - applying both, physiological and molecular methods. My methodological approach includes organ perfusions, ion-flux measurements over epithelial surfaces, gene expression analysis of respective epithelial transporters, as well as general molecular cloning techniques and cell culture.
