PhD in Neuroscience, University of Pennsylvania BSc in Biology and Psychology, University of South Florida
Karolina Skibicka, PhD, universitetslektor (docent) i fysiologi, undersöker beteendemässiga och neuroendokrina processer som styr grundläggande homeostatiska- och belöningskontroller av matintag och i slutändan hur dessa system kan leda till fetma. Målet är att identifiera en mer effektiv behandling riktad mot de neuralkretsar som ligger bakom överätning.
