Brandon L. Pearson
Brief Summary of Research
Brandon Pearson studies genetic and environmental contributors to risk for developmental and aging associated disorders. His lab is currently focused on identifying origins of somatic mosaic mutation in the brain and the role of environmental exposures in trinucleotide repeat disorders such as Huntington’s disease. To this end, his lab uses cellular models, mice, and a short-lived fish species with sporadic neurodegeneration, the African Turquoise Killifish.
"My lab studies molecular and cellular mechanisms of developmental, psychiatric, and aging-associated disorders. Our overarching goal is to identify causal environmental and genetic factors. My research is inspired by 1) our exceptionally poor understanding of brain - behavior relationships in disease alongside 2) the enormous psychosocial, medical, and economic burdens of chronic brain and aging-associated diseases. My group searches for etiologies and mechanisms by leveraging a wide array of experimental and observational systems. We apply computational approaches, tissue culture, animal models (mice and fish), and human biospecimens. Our ultimate goal is to identify key molecular initiators of pathology in order to reveal viable opportunities for primary prevention– particularly for conditions that are sporadic and/or have a long latent progression. A current focus is determining how (and which) environmental exposures during developmental periods program molecular signatures involved in complex disease outcomes including autism spectrum disorder, Huntington’s disease, and brain aging."
