Maria Raven, MD, and Hemal Kanzaria, MD, lead BHHI’s research group COORDINATE Home (CrOss-sectOR Data INtegrAtion To End HOMElessness.) 

The team analyzes San Francisco’s Coordinated Case Management System (CCMS) to evaluate policy-relevant questions. CCMS links data on the use of the homeless, public health, substance use and mental health systems, jail, and ambulances.


Collaborating with the San Francisco Departments of Public Health and Homelessness and Supportive Housing, Drs. Raven and Kanzaria work closely with the BHHI data science and statistics team, project managers, a group of postdoctoral scholars, and other trainees to answer key policy questions. 

Their publications continue to generate considerable media attention and policy interest. They are now collaborating with UC Berkeley’s California Policy Lab on additional analyses.
