Dr. Christoffel aims to understand how chronic exposure to particular stimuli (i.e. stress, food, drugs) alters the functioning of specific neural circuits and investigates the mechanisms that regulate these experience-dependent changes. Current studies focus on 1) how experience-dependent plasticity in the nucleus accumbens regulates reward processing, with a focus on the consumption of palatable foods and stress modulation of food intake, and 2) examine the regulatory role of neuromodulators in hedonic feeding.

The ultimate goal of the Christoffel Lab’s research is to understand how adaptive changes in brain function occur and how this can lead to the development of psychiatric disorders. We employ cutting-edge technologies to understand the complex interactions of multiple neural systems that allow us to adapt to our environment and regulate motivated behavior.
