Faculty

Dr. Nancy Hanrahan is an associate professor and faculty member of the Center for Health Outcomes and Policy Research at the Penn School of Nursing. She is an experienced psychiatric mental health nurse and an expertise in the clinical-financial-outcomes relationship of the business of mental health care as a senior administrator.  As a health systems researcher, work includes random controlled trials of innovative models care that promote an integrated mind/body approach to mental and physical health care for people with serious mental illness and HIV. Her research explores quality and outcomes of inpatient psychiatric services, psychiatric nurse workforce, and innovative transitional care models for patients discharged from psychiatric hospital treatment.  Optimal systems of care for people with mental illness are needed at the macro and micro scale.  Currently, Drs. Hanrahan and Barry Silverman, from the School of Engineering, are building a simulation using systems science and agent based models to capture “real world dynamics” of the behavioral health system of Philadelphia; the objective is to provide decision support for public health administrators who have few tools to compare the effectiveness of interventions and manage the complexity of systems. 

John Keenan is Professor of Electrical & Systems Engineering at the University of Pennsylvania. Research areas include the biological and health effects of pollution, wastewater treatment, water resources engineering, environmental impact assessment, and hazardous materials in the environment. Recent research efforts include assessment and selection of waste heat utilization technologies focusing on steam electric power facilities; an analysis of water resources in selected countries of the Middle East; development of single sludge wastewater treatment technologies; production and control of landfill leachates; development of expert systems for remediation of hazardous waste sites.
