Keith Choate M.D., Ph.D., is a physician-scientist who brings insights from skin biology research to his dermatology practice, specializing in complex cases unresponsive to first-line therapies. Dr. Choate is an attending physician at Yale-New Haven Hospital, the Yale Primary Care Center, Yale Dermatology Associates, and the Veterans’ Administration Hospital. He is the co-chief of Dermatology at the Saint Raphael's Campus of Yale-New Haven Hospital.

Dr. Choate provides care for patients with all dermatologic conditions and he has special interest in:

  • atopic dermatitis (eczema)
  • autoimmune blistering disorders including pemphigus and bullous pemphigoid
  • inflammatory disorders such as lichen planus, pityriasis rubra pilaris, and severe acne
  • genetic disorders including disorders of keratinization, and cutaneous mosaic disorders
  • psoriasis
  • skin cancer

Dr. Choate uses a wide variety of treatment modalities including phototherapy, systemic immunosuppressive agents, retinoids, and newer disease-targeted biologic agents including adalimumab, etanercept, infliximab, ustekinumab.

Patients are seen in consultation after referral by a dermatologist or primary care physician, typically after first-line therapies have failed.

In his research, Dr. Choate uses cutting-edge next generation sequencing technologies to identify mutations causing genetic skin diseases and his group studies the function of identified genes in normal and disease states. Dr. Choate has published over 30 peer-reviewed articles and chapters and presents his work at national and international meetings. He is a member of the Medical and Scientific Advisory Board for the Foundation for Ichthyosis and Related Skin types.

Dr. Choate mentors undergraduate, graduate, and medical students in his laboratory, teaches at Yale Medical School, and trains resident physicians and fellows.
