The Laboratory for Brain and Cognitive Health Technology (BaCH Tech Lab) is part of the Institute for Technology in Psychiatry at McLean Hospital and Harvard Medical School.

The BaCH Tech Lab uses digital technology to understand  the causes and consequences of variations in brain and cognitive functioning.  We build and validate web / mobile assessment tools that combine careful psychometrics and iterative software development to quantify behavior in large samples.  We also build tools for participant engagement, using return of research results to make our studies as meaningful to participants as they are to researchers.
