I am part of the convergence environment at the University of Oslo. I study how the crucian carp, one of the champions of anoxia tolerance, reduced its metabolism to prevent anoxic and oxidative damages. My goal is to identify key signalling pathways that can then be targeted to reduce ischemia-reperfusion injuries and inflammation with the aim to increase availability and function of donated organs for transplantation.

Research Interests

My research interests centre on how ectotherms cope physiologically with abiotic challenges they face in their environment. I mainly study fishes and insects but I am interested in all species. I have expertise in mitochondrial physiology and nitric oxide signalling and focus on the regulation of central physiological processes (osmoregulation, cardiac function, metabolism and respiration) and how they shape a species’ environmental tolerances/limits. I combine a broad array of tools in molecular and cellular biology (qPCR and Western blotting), physiology (Ussing chamber and everted gut sac), microscopy-based techniques (immunohistochemistry), and respirometry (OROBOROS) to integrate observations at different levels of biological organization. I am also beginning to delve into ‘omics, adding a discovery-driven approach to my repertoire to identify novel physiological targets.
