Robert Pesek

Robert Pesek, MD serves as an Assistant Professor of Allergy and Immunology at the University of Arkansas for Medical Sciences (UAMS) College of Medicine and Arkansas Children's Hospital (ACH), where he also directs the Allergy and Eosinophilic Gastrointestinal Disorders Clinics. His academic appointments span Pediatrics and Allergy/Immunology divisions within the Department of Pediatrics.

Dr. Pesek's research focuses intensely on primary immunodeficiency disorders, food allergies, and eosinophilic gastrointestinal diseases, particularly eosinophilic esophagitis. His work bridges clinical care and translational research, examining disease mechanisms, therapeutic interventions (including biologics like dupilumab), and patient outcomes across pediatric populations. Recent publications highlight multidisciplinary care models for severe asthma, food allergy tolerance induction, and clinical severity metrics for eosinophilic disorders.

Analysis of his 15 most recent publications (2020-2025) reveals a dominant focus on pediatric eosinophilic gastrointestinal disorders (73% of articles), with significant contributions to asthma management (20%) and food allergy research (13%). His collaborative work frequently appears in high-impact journals including New England Journal of Medicine and Journal of Allergy and Clinical Immunology, often involving multicenter consortia like CEGIR/TIGERs.

As Principal Investigator, Dr. Pesek has secured multiple research grants including UAMS ACHRI Flow Through projects (2015-2024) focused on eosinophilic research training and clinical investigations. His collaborations span institutions nationwide, with frequent co-authorship with UAMS colleagues including Stacie Jones, Amy Scurlock, and Tamara Perry.

Dr. Pesek maintains active membership in major professional societies: American Academy of Allergy, Asthma & Immunology; American College of Allergy, Asthma & Immunology; American Academy of Pediatrics; and Arkansas Medical Society. His clinical leadership extends to directing specialized allergy clinics at Arkansas Children's Hospital.
