Research Interests

I am a health services researcher and nationally-recognized expert on the nurse practitioner workforce. My work examines the role of the nurse practitioner to improve care delivery and outcomes within the contexts of an evolving healthcare system and policy reform. I am also interested in role transition for the novice nurse practitioner and finding ways to support new nurse practitioners as they enter clinical practice.

I direct the DNP Program and teach in the DNP and PhD programs. I am passionate about mentoring students to explore their interests as the develop their own clinical and research scholarship.

I have expertise in secondary data analysis using large data sets, primary data collection, advanced statistical methods, and instrument development. I have published and presented my research widely for nursing and interdisciplinary audiences. I completed an NINR T32 post-doctoral research fellowship in the Center for Health Outcomes and Policy Research at the University of Pennsylvania School of Nursing.
