Biosketch

Dr. Arissa Torrie is a dual-appointed Assistant Professor in the Departments of Anesthesiology and Orthopedics at the University of Maryland School of Medicine, with fellowship training in trauma anesthesiology from the R Adams Cowley Shock Trauma Center and regional anesthesia and acute pain from the Hospital for Special Surgery. Practicing at one of North America's busiest orthopaedic trauma centers, she integrates clinical care with research to advance evidence-based perioperative management. Her research focuses on improving outcomes for patients with orthopaedic injuries through innovative perioperative interventions. Her work bridges critical knowledge gaps between anesthesiology and orthopaedics, with an emphasis on developing practice-changing clinical trials that enhance recovery and quality of care.
