Christian A. Wysocki, M.D., Ph.D., is an Associate Professor in the departments of Internal Medicine and Pediatrics at UT Southwestern Medical Center. He serves as the Clinical Director of the Primary Immunodeficiency Program in the Division of Allergy and Immunology, a comprehensive clinical program dedicated to the diagnosis and multidisciplinary care of pediatric (and adult) patients with primary immunodeficiency disorders, in which he oversees the close collaboration of a number of disciplines, including bone marrow transplant, gastroenterology, rheumatology, hematology/oncology, infectious diseases, and basic immunology and translational research scientists.

Originally from Buffalo, New York, Dr. Wysocki holds a bachelor's degree in molecular biology and marine biology from the Florida Institute of Technology in Melbourne, Florida. He earned his medical degree and doctoral degree in microbiology and immunology at the University of North Carolina at Chapel Hill School of Medicine. He completed a residency in internal medicine at Yale University, where he also received advanced training through a fellowship in allergy and clinical immunology, with additional focused training in clinical immunology and primary immunodeficiency through the Clinical Immunology Society Summer School and USIDNET Visiting Immunology Scholars Program.

Certified by the American Board of Internal Medicine and the American Board of Allergy and Immunology, he joined the UT Southwestern faculty in 2013.

His ongoing research initiatives include a program directed at discovering new genetic abnormalities causing immunodeficiency or other immunologic disorders, which for Dr. Wysocki represents a longstanding collaboration with Nicolai Van Oers, Ph.D., in the Department of Immunology. He also works in concert with Dr. Van Oers on projects focused on the development of the thymus (a crucial organ in the development of the immune system) and genetic disorders that impact this process.

Other interests include collaborative projects focused on hemophagocytic lymphohistiocytosis (HLH) in both pediatric and adult patients, as well as projects focused on the autoimmune and inflammatory complications of common variable immunodeficiency (CVID).

Dr. Wysocki is a member of the American Academy of Allergy, Asthma, and Immunology and the Clinical Immunology Society. In addition, he serves as an immunologist consultant for the newborn screen lab for severe combined immunodeficiency (SCID) for the Texas Department of State Health Services.
