Dr. Fried specializes in pediatric immunology and allergy with clinical expertise in allergic rhinitis, allergy immunotherapy, anaphylaxis, asthma, eosinophilic esophagitis, food allergy, and primary immunodeficiency. His research focuses on understanding immune disorders in children, particularly primary immunodeficiencies, viral susceptibility in immunocompromised patients, and novel treatment approaches for eosinophilic disorders. His work bridges clinical practice with basic science investigations to improve diagnostic and therapeutic approaches for complex immune conditions.

Dr. Fried's publication record reveals a strong focus on translational immunology research with emphasis on primary immunodeficiency disorders, viral susceptibility in immunocompromised patients, and innovative treatment approaches for eosinophilic disorders. His work spans from basic molecular mechanisms of immune dysfunction to clinical guidelines for managing complex allergic conditions. Recent publications demonstrate particular interest in understanding SARS-CoV-2 susceptibility in immunodeficient patients and refining diagnostic approaches for immune disorders through biomarker analysis.

Dr. Fried is board certified by the American Board of Allergy & Immunology. He is actively involved in the clinical care of children with complex immune disorders through the various programs within the Division of Immunology at Boston Children's Hospital, including the Allergy and Asthma Program, Primary Immunodeficiencies Program, and related specialty clinics.

As an Assistant Professor at Harvard Medical School, Dr. Fried contributes to the education and training of medical students, residents, and fellows. He participates in the clinical fellowship training programs for young physicians specializing in allergy and immunology at Boston Children's Hospital, which is recognized as a major site for NIH-funded research and a leading center for clinical and basic investigation in pediatric immunology.

Dr. Fried works within the Division of Immunology at Boston Children's Hospital, which provides evaluation and treatment for patients with asthma, allergies, immune system disorders, skin diseases, and rheumatologic conditions. The division operates across seven sites in the greater Boston area and is recognized as a founding site of the International Consortium for Immunodeficiency, a Food Allergy Research & Education (FARE) Center of Excellence, and a Federation of Clinical Immunology Societies (FOCIS) Center of Excellence for immunodeficiency.
