April Lynn Ehrlich, MD

Assistant Professor, Medicine - (Clinical Scholar Track)
Chief for Clinical Research Development, Division of General Internal Medicine, Geriatrics, and Palliative Medicine

Dr. Ehrlich’s clinical practice focuses on both inpatient and outpatient geriatric consultation, giving her firsthand insight into the complications older adults face in hospitals. These experiences drive her research, which centers on developing evidence-based strategies to improve care for older adults with physical and cognitive frailty.

She completed advanced research training through an NIA-funded T32 program at Johns Hopkins, where she contributed to a transdisciplinary project demonstrating the value of geriatric surgical pathways in improving outcomes and reducing costs. Her current research targets delirium, particularly its onset in the emergency department — a critical issue worsened by ED boarding and hospital overcrowding. Through systems-based interventions, she aims to prevent delirium and its downstream consequences, including dementia.

As a clinician-researcher, her work bridges frontline care and research to drive meaningful improvements in geriatric care. She is passionate about making all places age-friendly and supporting the health of aging adults.
