David Hughes

David Hughes has worked for more than 20 years on projects related to analyses of health care system utilization and cost assessment, behavioral health services research, evidence-based practices, cost simulation models for planning behavioral health systems, and the intersection of the behavioral health and criminal justice systems. He is currently the Project Director for the Maine Health Data Warehouse Project which involves building a highly secure and robust data warehouse to collect and house health care claims, and other relevant information.

Dr. Hughes is also the Project Director for the California Health Reform Initiative which is using Medicare and Medicaid claims data as well as data from the state mental health and substance use authorities to examine how the health reform initiative will impact the behavioral health system in California. In addition, Dr. Hughes serves as a Senior Research Specialist for the SAMHSA-funded National Evaluation of SAMHSA’s Homeless Programs; and was the Behavioral Health Technical Assistance Director on the CMS-sponsored National Quality Enterprise. He has directed several federal multi-site studies, and was the Technical Assistance Provider to CMS Real Choice Systems Change Transformation grantees. He also served as the Project Director and Developer for the Mental Health/Jail Diversion Resource Allocation and Planning Model Project, a project funded by the Center for Mental health Services to develop a computerized budget simulation and resource allocation model for projecting the costs and potential cost offsets of implementing jail or prison diversion programs for offenders with mental illness and substance use disorders.

Valerie Bradley

President Emerita

Valerie Bradley

Valerie Bradley, who has a lifelong interest in public policy, is a co-founder of the Human Services Research Institute and guided the organization from 1976 to 2016. Under her leadership, HSRI became a leading resource for public managers in human services across the country. After getting her Masters in Political Science at the Eagleton Institute of Politics, she began her work in the 1960s as a staffer to the California Assembly where she contributed to the development of landmark legislation in mental health and developmental disabilities. Her interest in reform has been manifest in her involvement in a number of important issues including quality improvement, family support, deinstitutionalization, and performance measurement. In the mid 1970s, Ms. Bradley authored a book on deinstitutionalization which began her decades long interest in the adoption of policies that would move people out of large custodial institutions. Most notably, Ms. Bradley was the co-director of the Pennhurst Longitudinal Study – a five year study of the ultimate closure of Pennhurst State Center in Pennsylvania. She has also been concerned with the quality of community services and supports, and that concern led to her explore best practices in quality improvement around the country, to work with individual states to enrich their quality assurance systems, to edit two volumes on quality assurance, and more recently – and for the past decade, to her work with the Centers for Medicare and Medicaid Services as a provider of technical assistance to state waiver managers.

In the 1980s, Ms Bradley and her colleagues worked to amplify the voices of families with children with disabilities in the formation of public policy. With support from the Administration on Developmental Disabilities and the U.S. Department of Education, Ms. Bradley led efforts to organize families in a number of states to initiate legislation that established flexible and family centered community supports. More recently, Ms. Bradley helped the Institute to forge important collaborations – the most important of which is with the National Association of State Directors of Developmental Disabilities. This partnership has resulted in the creation of National Core Indicators – a performance measurement system that facilitates state by state comparisons and that has generated perhaps the largest database of individuals with intellectual and developmental disabilities in the country if not internationally.

Ms. Bradley has also made contributions beyond her work at the Institute including as the Chair of the President’s Committee on People with Intellectual Disabilities under President Clinton, and as President of the American Association on Intellectual and Developmental Disabilities. She has received numerous awards including the Compass Award from the National Association of State Directors of Developmental Disabilities Services.
