researchwebsiteDr. Zawia’s research deals with two aspects: the latent effects of environmental insults on the developing brain, and discovery of a novel class of mechanism-based drugs for the treatment of Alzheimer’s disease (AD). His research group focuses on lead (Pb) as a model environmental hazard to which early-life exposure reprograms gene expression impacting the neurodegenerative process in the aging brain.

His group has provided the first basic science evidence of the role of epigenetic pathways and factors in mediating latent effects on disease due to developmental exposure, and in doing so have generated the first evidence for the developmental origins of Alzheimer’s disease. In addition to exploring environmental risk factors for neurodegenerative diseases, the lab has repurposed a novel class of mechanism-based drugs for the treatment of AD, of which a lead drug tolfenamic acid is under consideration for clinical trials.
