I am a Pulmonary and Critical Care Physician, clinical epidemiologist, and health services researcher methodologically focused on leveraging practice pattern variation to identify, compare, and implement care practices that improve health. My research focuses on improving the processes and outcomes of critical care by reducing complications of care, including atrial fibrillation during critical illness, complications of opioid use during mechanical ventilation, and complications arising from failure to account for patient preferences in healthcare delivery. I have a demonstrated track record of high impact research (1/1/2026: Google Scholar h-index 58, cited >14,000 times), with >300 publications, many as first or supervising author in high impact journals such as NEJM, JAMA, JAMA Internal Medicine, Lancet Respiratory Medicine, the American Journal of Respiratory and Critical Care Medicine, and Journal of the American College of Cardiology. I have received Research Honors from the United States Agency of Healthcare Research and Quality for The Outstanding Research Article of 2011, as well as the Young Investigator Award from the American College of Chest Physicians, and the Robert Dawson Evans Junior Faculty Merit Award from Boston University School of Medicine, and the American Thoracic Society Critical Care Assembly Mid-Career Achievement Award in 2025. I was the co-principal investigator of the Society of Critical Care Medicine International VIRUS COVID-19 registry, which established an international registry of >300 hospitals to collect real time, granular COVID-19 hospitalization data, and produced >20 research papers. I have been continuously funded by the NIH since 2012 and am currently Principal Investigator for NIH- and US Department of Defense-funded R01 awards with the purpose of testing novel methods to predict and target cardiovascular events to improve outcomes after sepsis, and to evaluate opioid use in intensive care and its ramifications on post-ICU opioid-related complications. I have had leadership roles within multiple institutional and national committees, including Chair of the American Thoracic Society Critical Care Assembly Early Career Professional Committee, and Associate Editor for Annals of the American Thoracic Society. As founding Co-Director of the Evans Center for Implementation and Improvement Sciences, I developed, taught and leveraged innovative designs to improve the rigor of efforts to change health care practice locally and nationally, and as founding Director of the Critical Care Epidemiology, Clinical, Health Services, Outcomes Research Unit for the BU Pulmonary Center, I supervised a team of critical care health services researchers. As the Inaugural Chair of the Division of Health Systems Science at UMass Chan Medical School I seek to lead a section dedicated to rigor and innovation within learning health systems research. As interim Director of the Institute for Healthcare Delivery Sciences I seek to establish a an infrastructure to convene learning health system collaboratories around projects that improve healthcare delivery. My mentorship has been honored with a Research Mentor Award for the Department of Medicine, and the Junior Faculty Mentorship Award from Boston University. I currently mentor multiple NIH K- and F32-award recipients who have gone on to R01-level funding.
