Biography

The overarching goal of my research is to determine how environmental factors (both natural and anthropogenic) shape metabolic phenotypes in teleost fish  across their life-cycle and between generations. The lab uses an integrative approach to characterize metabolic phenotypes at multiple levels of biological organisation, ranging from organismal to the cellular and molecular level approaches. A recent focus lies in determining the role of how epigenetic molecular mechansisms, especially microRNAs, regulate fish metabolism in response to environmental stimuli, both within the life-cycle of fish and across generations.

Experimental models include rainbow trout and zebrafish, which allow to extend basic research to aquaculture and aquatic toxicology.
