People
Informaticians, data scientists, and software developers in the Department of Biomedical Informatics at Vanderbilt University Medical Center.

Alvin D. Jeffery, PhD, RN, CCRN, FNP-BC
Assistant Professor of Biomedical Informatics and Nursing
Dr. Jeffery completed his PhD (Nursing Science & Health Services Research) at Vanderbilt University’s School of Nursing in 2017 and a Medical Informatics Post-Doctoral Fellowship with the U.S. Department of Veterans Affairs and Vanderbilt University’s Department of Biomedical Informatics in 2019.
He previously held an AHRQ/PCORI K12 focused on Learning Healthcare Systems and Implementation Science as well as the highly-selective Betty Irene Moore Fellowship for Nurse Leaders and Innovators. He is currently funded by the NIH to develop precision phenotypes for substance use disorders with the aim of accelerating genetics studies.
He came to informatics from pediatric critical care nursing and a staff educator role at Cincinnati Children’s Hospital Medical Center, and is board certified in that specialty and as a Family Nurse Practitioner. He is a former Emerging Leader with the Alliance of Nursing Informatics.

Ransom Wyse, MPH, CPH
Program Manager
Ransom is an epidemiologist who works in Dr. Alvin Jeffery’s team as a Program Manager. Ransom has been working on aspects of the DP1 grant, “Framework to Accelerate Substance Use Disorder Genetic Studies through Customizable, EHR-Based Precision Phenotyping,” including writing articles regarding natural language processing, phenotyping for case definitions, and clinical decision support tools. His work directly contributes to the mission of VUMC via his expertise; his analytics and interpretations of our research findings will inform best-practices for SUD identification in an at-risk population, which can be used by the scientific and clinical community to improve patient healthcare.
