My research fields are at the intersection of evolutionary ecology, ecophysiology and behavioral and environmental ecology. I am broadly interested in the proximate physiological mechanisms underlying variation in phenotypic, behavioral and fitness traits and their plasticity. I want to understand how physiologically-regulated traits enable organismal adaptation to changing environmental conditions and play a part in species interactions, potentially even affecting population processes. I am also interested in how interactions with microbes (gut microbiome) relate to phenotypic variation in wild populations.  I further want to understand more broadly how various early-life environmental conditions affects offspring development and fitness with a specific interest in non-genetic inheritance, such as maternal effects and epigenetics​
