The Criscitiello Comparative Immunogenetics Laboratory studies immunology, molecular genetics and evolution. Most of his group’s research focuses on the natural history and future application of the vertebrate adaptive immune system, with particular attention given to the genetics of lymphocyte antigen receptors. Particular expertise lies in the evolution of vertebrate immunoglobulin loci, T cell receptor loci and the major histocompatibility complex. Additionally, his team is interested in the evolution of diversification mechanisms at work there (e.g., recombination activating genes (RAG), activation-induced cytidine deaminase (AID), and the high allelic polymorphism. Most recently, they have been working on lymphocyte development in shark thymus that suggests plasticity across the B lymphocyte/T lymphocyte divide, immunoglobulin heavy and light chain isotype pairing in an amphibian system, immunogenetics in marine mammals of conservation importance, mucosal humoral immunity in diverse tetrapods and cattle antibodies with an unheralded domain extending for novel antigen binding possibilities. His laboratory has contributed to changes in our understanding of lymphocyte antigen receptor repertoire diversification and the evolution of the peculiar genetics responsible for our anticipatory immune response.

Dr. Criscitiello’s service is centered in graduate programs (Biomedical Sciences, Medical Sciences, Genetics, Biotechnology, Ecology and Evolutionary Biology, Toxicology and Reproductive Sciences), student committees, research infrastructure and high school science outreach. Since 2017 he has served as Assistant Dean for Research and Graduate Studies in the College of Veterinary Medicine and Biomedical Sciences. His teaching is focused on immunology and genetics at the senior undergraduate and graduate levels. He is passionate about better mentoring and menteeing. He is director of the American Association of Immunologists High School Teacher Program and is Vice President for the Americas of the International Society for Developmental and Comparative Immunology.
