Dr. King received his medical education from Penn State College of Medicine, and completed Internal Medicine residency and chief residency at the University of Virginia. He completed Nephrology fellowship at Johns Hopkins Hospital, and after returning to the University of Virginia as a nephrologist, completed a medical toxicology fellowship there.

Dr. King is a clinician-educator nephrologist and medical toxicologist with clinical interests in extracorporeal treatment of poisonings, extracorporeal removal of therapeutic drugs, ICU nephrology, and medical education. As a clinician, He sees hospitalized patients at the University of Maryland Medical Center on our nephrology consultation service as well as our medical toxicology consult service. He is  involved in education primarily at the graduate medical education level, and to a lesser extent undergraduate medical education.

Dr. King is also the medical director of the Maryland Poison Center, which provides poisoning information and treatment recommendations benefitting thousands of Marylanders each year. Dr. King carries out medical oversight of recommendations for poisonings, envenomations, and overdoses to the public and health care providers; provides education to a variety of students (pharmacy and medical) and physicians (residents and fellows) who rotate with the center; He is involved in a variety of other activities aimed at treatment and prevention of poisoning.

Dr. King's research interests are largely focused where nephrology and toxicology meet – extracorporeal removal (via dialysis, apheresis, and other modalities).
