Nilanjana Dwibedi, MBA, PhD: Dr. Dwibedi’s research interests include assessment of patient reported outcomes measures, medication error prevention, evaluating medication adherence, applying new methodology to conduct pharmacoepidemiology research and evaluating impact of new technology in US healthcare systems.

 
 

Kimberly Kelly, PhD, MS:  Three overlapping themes emerge from Dr. Kelly’s research: (1) cancer risk perception/communication, (2) health behavior (e.g., cancer screening, genetic testing), and (3) elevated risk populations (e.g., Appalachians, those with a family history of cancer). Her work relies on behavioral theory from psychology (health, social, cognitive), as well as communication and information sciences. She mixes qualitative and quantitative methods, utilizing clinic-based and community-based approaches. Most of her research has focused on how risk is communicated in the context of cancer genetic counseling and how risk perceptions differ from objective estimates of risk. She also examines the role of risk perception in cancer screening. Through her research, Dr. Kelly hopes to understand how best to enhance appropriate decision-making about health behaviors in elevated risk populations to accomplish optimal health outcomes.

Traci J. LeMasters, PhD: Dr. LeMasters research interests lie within the fields of pharmacoepidemiology, health services, and outcomes research. Her topics of study have included cancer risk, prevention, treatment patterns, and survival outcomes, including survival analysis and health related quality of life (HRQoL). Her research has been heavily focused on these issues as they pertain to breast cancer, and more recently, the relationship between mammography screening, guideline recommendations, and the risk for false-positives.

Suresh Madhavan, MBA, Ph.D., FAPhA: Dr. Madhavan’s primary areas of research interests include health services research and health policy, with particular emphasis on improving access to and quality of health and preventive care services, and the cost-effective use of drugs in healthcare systems. Dr. Madhavan’s research has focused on cost-effectiveness and budgetary impact of preventive drug therapies in public programs like Medicaid and the state government employees’ insurance program.

Usha Sambamoorthi, PhD: Dr. Usha Sambamoorthi has doctoral training in Economics with a specialization in Labor Economics. She effectively utilizes statistical and analytical expertise in her independent research as well as in collaborative research with physician researchers, sociologists, epidemiologists, statisticians, economists and psychologists as evidenced by numerous authored and co-authored peer-reviewed publications. Dr. Sambamoorthi ’s interest in the multidisciplinary perspective to problems has shaped the approach she has taken to health care research. She believes that a multidisciplinary and holistic approach is essential to developing treatment plans and healthcare policy that are ideally-suited to the complicated illness trajectories, treatment regimens, and the complex psychological, social, and economic circumstances of many of the disadvantaged patients with chronic physical and mental health conditions. To date Dr. Sambamoorthi has over 140 publications out of which 90 have either her or her mentees as the primary author. She has received funding research support from federal agencies such as AHRQ, NIH, NIA, NIMH, VHA HSR&D, the private corporation Sanofi, and the private foundation, Benedum. Through research support from these grants, Dr. Sambamoorthi mentors junior faculty members and many graduate students in real-world analysis of high-quality health economics and outcomes research.

Stephen Small, MS, RPh: The themes of Mr. Small’s research are: (1) Medication Error Prevention (2) Medicaid Manage Care and (3) Pharmacy Prior Authorization processes.
