The IDRIS lab is a research group based in the Maryland Psychiatric Research Center (MPRC) in Baltimore, which is part of the University of Maryland School of Medicine.


Our research is focused on schizophrenia and related psychiatric disorders, and more specifically, on how differences in learning and decision-making in people with schizophrenia relate to symptoms, functional outcome and therapeutic interventions. 


Schizophrenia is a debilitating disorder of the brain that affects around 1% of the world's population. To read more about what schizophenia is, and how it affects people's lives, click here.
