Brett King, MD, PhD, a Yale Medicine dermatologist and associate professor of dermatology at Yale School of Medicine, specializes in skin diseases refractory to first-line therapies. 

Dr. King has pioneered the use of Janus Kinase (JAK) inhibitors in dermatology, and his work has revealed the broad utility of JAK inhibitors for the treatment of alopecia areata, vitiligo, granuloma annulare and sarcoidosis, lichen planus, and atopic dermatitis. 

Dr. King is an internationally recognized expert in alopecia areata, a chronic skin condition that causes patchy hair loss or even loss of all body hair. 

When people have this condition, the body’s immune system attacks the hair follicles. It can lead to the loss of hair on the head, eyebrows, eyelashes, beard and/or body. Dr. King understands the profound consequences this often has on peoples’ lives.  “Alopecia areata causes so much anxiety and despair for patients and their families—it can be devastating,” he says.

Dr. King is an investigator in numerous clinical trials. He has lectured nationally and internationally and has published extensively.
