Dr. Peisong Gao is an Assistant Professor of Medicine in the Allergy and Clinical Immunology division at the Asthma and Allergy Center. He studies the immunological and genetic regulation of allergic diseases.

Dr. Gao holds bachelor's and medical degrees from The Fourth Military Medical University in China. He received a Ph.D. in Experimental Medicine from the University of Wales Swansea and completed a fellowship at Churchill Hospital at Oxford University before joining the Johns Hopkins faculty in 2007. He is a member of the American Academy of Allergy, Asthma, and Immunology, the American College of Allergy, Asthma, and Immunology, the Genetics, Molecular Biology, and Epidemiology Committee and the David G. Marsh Grant Review Committee. His work has been recognized with an AAAAI/Sepracor Research Excellence Award in 2004, an Annual Respiratory Disease Young Investigator Award in 2005, an Interest Section Award from the American Academy of Allergy, Asthma, and Immunology in 2007, an American Lung Association of Maryland Award in 2007, a Johns Hopkins Clinical Research Junior Faculty Award in 2009 and an Outstanding Pediatric Allergy, Asthma, and Immunology Award from AAAAI in 2010.
