Elizabeth Schierholz.jpegElizabeth Schierholz, PhD, NNP-BC

Postdoctoral Fellow

Dr. Schierholz is a first year postdoctoral fellow in the Data Science to Patient Value Pr ogram. She holds a BSN in Nursing from the Scott and White School of Nursing at the University of Mary Hardin Baylor, a MSN as a Neonatal Nurse Practitioner from the University of Pennsylvania and a PhD from the Center for Health Outcomes and Policy Research at the University of Pennsylvania’s School of Nursing. 
Her fellowship at the Center for Health Outcomes and Policy Research at the University of Pennsylvania focused on health services research, health policy, innovation and improvement of health care systems with an emphasis on the impact of patient safety and patient outcomes. Her dissertation work asked the research question “Are the quality of nurse work environments and the qualifications of the registered nurses in neonatal intensive care units related? and how are these factors individually or jointly related to mortality, intraventricular hemorrhage and length of stay for very low birth weight infants?” The results of the study indicate that very low birth weight infants, cared for in the best work environments have lower risk adjusted rates of severe intraventricular hemorrhage and shorter lengths of stay.  
Dr. Schierholz currently practices as a Neonatal Nurse Practitioner in the Neonatal Intensive Care Unit at the Children’s Hospital of Colorado. Her professional and research areas of interest include healthy work environments and organizational culture, team work, effective team member communication, provider decision, patient safety, neonatal resuscitation, simulation education, and neonatal transport.

John WeltonJohn Welton, PhD, RN, FAAN
Professor, College of Nursing

John Welton's career research interests touch on expansive ideas: How much does nursing care cost? How can we build a better nursing care system to improve efficiency, effectiveness, performance, quality, and ultimately the value of the work nurses provide to their patients? His interests started early in his career during his MSN degree program at University of North Carolina-Charlotte, where his Nursing Administration thesis project was a financial analysis of, and business plan for, an air-ambulance company. The financial numbers for the company looked so good that Welton became a nurse entrepreneur, launching National Medevac, Inc. A few years later, he met Dr. Edward Halloran at the University of North Carolina-Chapel Hill, where he completed his PhD in Nursing Systems. Subsequently, his academic career path took him to the University of Maryland School of Nursing, to Medical University of South Carolina in Charleston, and just previous to CU, to Florida Southern College.
