Erryne Pearl Enriquez, RN
Erryne is a research nurse manager, bringing nine years of oncology nursing experience to her work in mast cell disorders and secondary immunodeficiencies. She plays a key role in coordinating and executing industry-sponsored clinical trials, overseeing protocol implementation, patient enrollment, regulatory compliance, and ensuring clinical data integrity. She collaborates closely with physician investigators and multidisciplinary teams to advance high-quality, patient-centered research. She is currently pursuing a Master of Science in nursing with a concentration in nurse executive leadership. With this she hopes to focus on clinical operations, research excellence, and program development.

Lauren Chapman, RN
Lauren is a clinical nurse specialist. Bringing four years of experience from bone marrow transplants and hematology, along with a background in clinical research, she works closely with patients and investigators to further research in the immuno-compromised population. Beginning at Huntsman Cancer Institute in Utah and moving to Baltimore to work at Johns Hopkins Hospital, Lauren is dedicated to studying how to decrease mortality in those with secondary immunodeficiencies. She is also a graduate student, working toward a master's degree in microbiology and immunology.
Maria Leondaridis, Research Associate
Maria Leondaridis, Research Associate
Maria is a graduate student in the laboratory of Dr. Snow in collaboration with Dr. Boggs to better understand how mutated KIT proteins differentially affect downstream signaling programs. Maria developed a novel 293T transfection assay to assess the function of expressed KIT variants in well-differentiated systemic mastocytosis through KIT autophosphorylation signaling. The goal of this work is to understand how KIT mutations result in specific downstream signaling programs and determine their pathogenicity via functional testing. She plans to dissect how these programs connect to a variety of clinical phenotypes including systemic mastocytosis, gastrointestinal stromal tumors, and pediatric cutaneous mastocytosis. Additionally, she has started a tryptase genotyping project to help unravel the potential role of tryptase in chronic spontaneous urticaria.
CPT Jeremy McMurray, MD
CPT Jeremy McMurray, MD
Dr. McMurray is an assistant professor in the departments of both pediatrics and medicine. He began his military career with a commission from West Point in 2015. He then received a medical degree from USU in 2019. He completed a pediatrics residency in 2022 and an allergy and immunology fellowship in 2024 at Walter Reed National Military Medical Center. He is board-certified in both allergy and immunology and pediatrics. Dr. McMurray is currently involved in allergy and immunology clinical research focused on systemic mastocytosis and venom allergy. He serves as an associate investigator on the TL-895 clinical trial for treatment of indolent systemic mastocytosis (NCT04655118) and as a writing group member for the updated 2026 insect allergy practice parameters.
MAJ Luke Pittman, MD
MAJ Luke Pittman, MD
Dr. Pittman is an assistant professor of medicine. He currently serves as the Program Director of the National Capital Consortium's allergy and immunology fellowship program at Walter Reed National Military Medical Center. He is also Deputy Consultant to the U.S. Surgeon General for Army allergy and immunology and the primary consulting allergist and immunologist for the White House Medical Unit. His research interests include secondary hypogammaglobulinemia, immunoglobulin replacement, allergen immunotherapy, novel targeted therapeutics, and food allergy. He currently serves as the Walter Reed site Principal Investigator for a phase III clinical trial investigating Xembify 20% subcutaneous immunoglobulin replacement versus placebo for the prevention of major bacterial infections in adult patients with hematologic malignancies, hypogammaglobulinemia, and recurrent or severe infections (NCT05645107).

He is board-certified in both allergy and immunology and pediatrics. Dr. Schornack is currently involved in clinical allergy and immunology research with a focus on inborn errors of immunity, mastocytosis, urticaria, and food allergies.
Andrew Snow, Ph.D.
Andrew Snow, Ph.D.
Dr. Snow is a professor in the Department of Pharmacology & Molecular Therapeutics. His current research program focuses on how genetic and molecular aberrations in antigen receptor signaling pathways contribute to changes in lymphocyte survival, differentiation and function, informed by human monogenic disorders associated with immune dysregulation and/or immunodeficiency. His laboratory has discovered and extensively characterized many gain- and loss-of-function mutations in the lymphocyte scaffolding molecule CARD11, which give rise to selective B cell lymphoproliferation or severe atopic disease, respectively, in human patients. He is investigating how aberrations in signaling, metabolic, and cell death pathways in B and T cell lymphocytes manifest in immune dysregulation, with the goal of developing therapeutic strategies that rebalance and optimize adaptive immune responses. His lab also works closely with Dr. Boggs’ team to advance mechanistic studies on Military Health System patients with undiagnosed inborn errors of immunity and/or adverse allergic responses related to mastocytosis.
