Overview

Dr. Geva conducts research at the intersection of biomedical informatics, health services research, quality improvement, and critical care medicine. Using methods learned during his NRSA fellowship with Dr. Kenneth Mandl, he applies computational methods to the study of health systems and, in particular, to the care of critically ill children. His current projects focus on cohort identification and characterization using electronic health records data, automatic patient registry population using electronic health records data, assessment of medication use and safety, and development of clinical decision support applications for the bedside.

Background

Dr. Geva is a board-certified in pediatric critical care medicine and practices in the Medical-Surgical and Cardiac Intensive Care Units. In addition to his clinical training at Harvard Medical School and Boston Children's Hospital, he completed a Masters in Public Health with a focus on Quantitative Methods at the Harvard T. H. Chan School of Public Health and a post-doctoral NRSA (T32) fellowship in Biomedical Informatics under the mentorship of Professor Kenneth Mandl.
