Dr. Arun Chandnani joins the Department of Medicine in the Division of General Internal Medicine as an Instructor as of July 2026.
He was born in Mobile, Alabama, and grew up across the Midwest, living in Cincinnati, Ohio, and Naperville, Illinois. He attended the University of Illinois at Urbana-Champaign, where he studied Chemical Engineering, developing a strong foundation in systems thinking and process optimization that would shape his approach to medicine.
Prior to pursuing a career in medicine, Dr. Chandnani worked as a process engineer at Procter & Gamble, where he gained valuable experience in operational efficiency, data-driven problem solving, and large-scale project management. This background in engineering and industry has informed his passion for hospital systems improvement and clinical process optimization — translating the principles of engineering into meaningful advances in healthcare delivery.
Dr. Chandnani received his medical degree from the University of Colorado School of Medicine in 2023, before completing his internship and residency in Internal Medicine at Barnes-Jewish Hospital/WashU Medicine. During his training, he has pursued research projects on various topics such as Inflammatory Bowel Disease, as well as quality improvement initiatives that bridge clinical medicine with operational and analytical work. He also enjoys teaching and working with medical students and residents.
His primary clinical interests include pulmonary and critical care medicine, with a particular focus on inpatient care and systems-level optimization. Outside of medicine, his hobbies include hiking, skiing, weightlifting, reading, and exploring new restaurants. He looks forward to continued growth as a clinician and contributor to academic medicine.
