In general, I do research on the psychological and neural basis of cognitive and emotional control, factors that diminish control such as aberrant salience, and the development of schizophrenia and its symptoms (e.g., psychotic symptoms, negative symptoms such as anhedonia).
In current studies, we are especially focusing on the nature of psychosis risk, including the involvement of striatal dysfunction, and how psychosis risk can be ameliorated.
