Nathaniel Bell, PhD

Nathaniel Bell

(PhD, Geography, Simon Fraser University)

Nathaniel Bell is an Assistant Professor in the College of Nursing. He is also affiliated with the Department of Surgery and the Arnold School of Public Health. He received his doctorate in Geography from Simon Fraser University in 2010. Prior to joining the University of South Carolina, he was a Canadian Institutes for Health Research Postdoctoral Fellow in the Department of Surgery at the University of British Columbia and the research manager for Trauma Services at Vancouver General Hospital.

Professor Bell’s research advances existing knowledge of anticipated and unanticipated effects of health care reform on the US population. Whether a proponent or a critic of many of the reforms occurring in parallel or as a direct result of the Patient Protection and Affordable Care Act, most scientists and stakeholders agree that a new era in health care in the US has begun. But how should successes of these policies be measured? Using linked administrative datasets, Professor Bell and his colleagues are designing studies to make inferences about the effects of health care policy reform when experimentation is not feasible. Fundamental to these studies is an underlying focus on social and environmental determinants that drive variations in outcomes achieved, such as the reduction of preventable mortality as a result of improved access to integrative primary care; the proportion of hospital readmissions that could be avoided had patients had access to outpatient health care services; the effect of patient socioeconomic status on pay-for-performance risk adjustment; as well as variation in health care outcomes relative to need, geography, and scope of practice restrictions.

Stephen M.

Dr. Gavazzi has established a research program that identifies the impact of family dynamics on adolescent development, psychopathology, and problem behavior. He has been involved in the development and evaluation of a number of family-based programming efforts, including a multifamily psychoeducation group for families containing children with mood disorders implemented and evaluated through a grant from the National Institutes for Mental Health. A family therapist by training, Dr. Gavazzi also has created the Growing Up FAST Program, a family-based diversion initiative for use with juvenile offenders and their families, that has been implemented and evaluated through a series of generous grants from the Ohio Office of Criminal Justice Services and the State of Ohio Department of Youth Services.

Currently, Dr. Gavazzi’s efforts are largely directed toward the development of a measure known as the Global Risk Assessment Device (GRAD), designed to measure assets and risks related to the adjustment and well-being of individuals involved in the justice system. Originally established through use with over 15,000 adolescents coming to the attention of the juvenile courts, this work most recently has been adopted for use with young offenders (18-25 years) who are incarcerated within the South Carolina Department of Corrections (SCDC).
