Research interests

Animals and humans constantly adapt to changes in the environment and make decisions that offer the most favourable outcome. My research focuses on understanding the neural basis of value- or stimulus-guided actions using in vivo techniques, such as chemogenetics and optogenetics, in combination with animal models of decision making. Ultimately, understanding the neural basis of psychological processes controlling action selection will have an impact on understanding and treating a wide range of diseases involving a loss of action control, such as addiction, major psychiatric disorders such as obsessive compulsive disorder, and neurodegenerative diseases.
