Research Interests

My research interest is to understand the chemical mechanisms that encode and maintain long-term memory. Currently, we investigate how learning imprints information onto the epigenome of participating neurons, and how these experientially-driven changes to the structure of the genome affect the expression of genes that facilitate plasticity. Using gene knockout models, antisense oligonucleotides, novel small molecules, and site-directed EpiTALEs, we probe the function of epigenetic modifying enzymes in and specific epigenetic markers of memory function. A major goal of our laboratory is to develop therapies that manipulate the epigenome to enhance cognition in cases of intellectual disability, such as Pitt-Hopkins Syndrome, and memory in Alzheimer’s disease.
