Elizabeth Colantuoni

Elizabeth Colantuoni, PhD, ScM, is a Research Professor in the Department of Biostatistics at the Johns Hopkins Bloomberg School of Public Health. She is actively involved in collaborative research with the Outcomes After Critical Illness and Surgery (OACIS) group at Johns Hopkins School of Medicine and serves as the lead Biostatistician for Dr. Aaron Milstone's research group. She is also the co-Director of the ScM and MHS graduate programs and teaches Methods of Biostatistics (140.653-4), focusing on regression methods.

Her educational background includes a PhD from the Johns Hopkins Bloomberg School of Public Health (2007) and an ScM from North Carolina State University (1999).

Colantuoni’s research focuses on improving outcomes for critically ill patients across all age groups. Her work addresses complex statistical challenges such as longitudinal data analysis with time-varying exposures, competing risks, and truncation by death in ICU studies. She develops and applies methods for analyzing functional and mental health outcomes in survivors of critical illness. She also works on pediatric and neonatal populations, particularly in infection prevention within NICUs. Her methodological interests include improving precision in randomized trials through baseline variable adjustment and handling survival outcomes without proportional hazards assumptions.

Her recent publications (including 2025 articles in press) span delirium trials, telehealth interventions, infection epidemiology, hospital fall risk, and laryngeal function post-extubation. These works reflect a strong trend in critical care biostatistics, patient-centered outcomes, and methodological innovation in clinical research.

Scientific Awards:

• OACIS-Mental Health group Team Science Award awarded by the Institute for Clinical and Translational Research, Johns Hopkins

Colantuoni advises on numerous research projects, including the OACIS and OACIS-Mental Health studies, the BrightStar collaborative, and Dr. Milstone’s neonatal infection research. She leads an R01-funded project from the NIA to develop statistical methods for delirium interventions. Her work bridges biostatistics, clinical medicine, and public health, with a strong emphasis on collaborative science and methodological rigor.

She is affiliated with the Department of Biostatistics at the Bloomberg School and contributes to major initiatives at Johns Hopkins Medicine, particularly in critical care and patient safety research.
