David Hagin, MD, PhD
University of Washington
David Hagin, MD, PhD, is a Senior Allergy and Immunology Fellow at the University of Washington and Seattle Children’s Hospital (SCH). His clinical interests include diagnosis and management of patients with primary immunodeficiency diseases (PIDD) and Immune Dysregulation. His research relates to identifying basic cellular mechanisms that underlie immunodeficiency and autoimmunity.
Dr. Hagin earned his medical degree from The Hebrew University Hadassah Medical School in Jerusalem, Israel, completed residency in Internal Medicine at Tel-Aviv Sourasky Medical Center, and received a PhD in immunology from the Weizmann Institute of Science.
Joud Hajjar, MD
Baylor College of Medicine/Texas Children's Hospital
Dr. Hajjar her medical degree from the University of Aleppo in Syria. She received her residency training at the American University of Beirut and Indiana University School of Medicine. Dr. Hajjar completed a fellowship at MD Anderson Cancer Center in Hospice and Palliative care, and then completed her fellowship in Allergy and Immunology at Virginia commonwealth. And she is currently completing her MS degree in clinical investigation. Dr. Hajjar is American Board certified in Internal Medicine, Allergy and Immunology.
Dr. Hajjar is an assistant professor at Baylor College of Medicine. She launched the transition program for adolescents and young adults with primary immunodeficiency at Texas Children's hospital. Her clinical interest include primary immunodeficiency disorders in adults, mast cell and eosinophil disorder. Dr. Hajjar's research is focused on clinical outcomes and quality of life in patients with primary immunodeficiency.
Elena Hsieh, MD
Children's Hospital Colorado - University of Colorado School of Medicine
Dr. Hsieh earned her MD degree from University of California San Francisco (UCSF) in 2008. She completed a residency in pediatrics at the University of California Los Angeles (UCLA) in 2011, and a fellowship in Allergy and Immunology at Stanford University in 2014. She continued her research and clinical work at Stanford University as an Instructor for an additional year. In 2015, Dr. Hsieh joined the faculty at the University of Colorado Denver School of Medicine, jointly affiliated with the Children’s Hospital of Colorado. Dr. Hsieh’s lab addresses mechanistic and translational questions in human immunology using high-dimensional single-cell mass cytometry and ex-vivo cellular manipulation. Their goal is to enable a deeper understanding of normal immune function, and dysregulated immune processes in immunodeficiency, autoimmunity, and the overlap between the two.
Andrew Snow, PhD
Uniformed Services University of the Health Sciences
Dr. Snow earned his Ph.D. from Stanford University in 2005, working with Dr. Olivia Martinez in the Transplant Immunology Laboratory. He then completed a postdoctoral fellowship with Dr. Michael Lenardo at the National Institute of Allergy and Infectious Diseases (NIAID), National Institutes of Health (NIH) in Bethesda, MD. In 2011, Dr. Snow moved across the street and joined the faculty at Uniformed Services University of the Health Sciences (USUHS) as an Assistant Professor in the Department of Pharmacology and Molecular Therapeutics. As a trained basic immunologist, Andy is primarily interested in the genetic and molecular control of immune homeostasis, with an emphasis on programmed cell death. His laboratory currently studies immune disorders (e.g. XLP-1, BENTA) characterized by defects in lymphocyte death and differentiation that result in abnormal lymphoproliferation and/or immunodeficiency.
Kelli W. Williams, MD, MPH
Clinical Assistant Professor
Medical University of South Carolina
Dr. Williams received her undergraduate degree in Chemistry from Colgate University in upstate New York. She earned her medical degree and Master of Public Health (in international health and development) from Tulane University in New Orleans, Louisiana in 2009. She completed her residency in Pediatrics at the Medical University of South Carolina (MUSC) in Charleston, South Carolina and her fellowship in Allergy and Immunology at the National Institute of Allergy and Infectious Diseases (NIAID), National Institutes of Health (NIH) in Bethesda, Maryland. In 2015, she returned to Charleston and is now a Clinical Assistant Professor at the Medical University of South Carolina. Outside of work, she enjoys the outdoors with her husband, two boys, and chocolate Labrador retriever. She is also a foodie, travel enthusiast, and avid Red Sox fan.
Caroline Kuo, MD
UCLA Medical Center
Los Angeles, CA
Dr. Caroline Kuo is currently Assistant Clinical Professor of Pediatrics in the Division of Allergy, Immunology, and Rheumatology at UCLA. She attended medical school at the Keck School of Medicine at USC, completed her pediatric residency at Harbor-UCLA and Allergy & Immunology fellowship at UCLA, and is board-certified in Allergy & Immunology.
Dr. Kuo is director of the UCLA Pediatric Immunology Clinic, focusing on the diagnosis and treatment of both pediatric and adult patients with immunodeficiencies and recurrent infections. For more than forty years, the Division has provided clinical care to patients with primary immune deficiencies and has made seminal contributions to improving treatment of individuals with these disorders. In recognition of these efforts, the Division has been named a Center of Excellence for the Diagnosis and Treatment of Primary Immunodeficiency by the Jeffrey Modell Foundation.
Dr. Kuo’s research investigates novel therapies for rare immunologic diseases, and her work has been funded by the UCLA Children’s Discovery and Innovation Institute, Harry Winston Foundation, Primary Immune Deficiency Treatment Consortium, and the NIH CHRC. She currently serves as the UCLA Site Principal Investigator for a Phase I/II clinical trial for patients with X-Linked Chronic Granulomatous Disease funded by the California Institute for Regenerative Medicine.
Yasmin Khan, MD
Dr. Khan grew up in a small town in Kentucky and received her undergraduate degree in Biology at the University of North Carolina at Wilmington. She then received a Masters of Science in Biochemistry/Molecular Biology at King’s College London. She received her medical degree from the University of Kentucky and completed residency and fellowship training at Vanderbilt University Medical Center, where she joined faculty in 2015. Her major clinical interest is in immunology and she has helped to found a multidisciplinary clinic for pediatric immunodeficiency at Vanderbilt.
