Assistant Professor, Medicine

Anica Law
72 East Concord Street


Dr. Law is a Pulmonary and Critical Care physician, clinical epidemiologist, and health services researcher with a focus on understanding determinants of outcomes after critical illness. An unprecedented number of patients now survive the intensive care unit (ICU) but suffer severe organ dysfunction, requiring forms of long-term organ support, such as mechanical ventilation or artificial nutrition. Using both granular clinical and national claims databases, and leveraging natural experiments where feasible (e.g., policy changes), the goal of her research is to better inform decision-making during critical illness and the optimal delivery of care after acute critical illness.

Dr. Law serves as Deputy Editor at CHEST Critical Care. Within the American Thoracic Society, she is Chair of the Critical Care Assembly’s Planning Committee.
