My primary research focuses on the effects of early-life iron deficiency on neural development. Iron deficiency is a major global health concern that affects conservatively 2 billion individuals worldwide, including about 30% of pregnant women and pre-school age children. It is well established that early-life iron deficiency has long lasting negative effects on cognition and socio-emotional behaviors in humans despite prompt iron treatment following diagnosis. These long-term effects constitute a significant cost to society in terms of educational attainment, job potential, and risk of mental health disorder. My lab investigates the cellular, molecular and epigenetic mechanisms underlying the long-term neurobehavioral effects of early-life iron deficiency in animal models. My secondary research interest focuses on investigating the biological role of a novel peptide (TMEM35a/NACHO), which has been recently discovered to function as an important chaperone for the assembly and trafficking of nicotinic acetylcholine receptors. These ligand-gated cation channels/receptors play pivotal roles in the pathogenesis of Alzheimer’s Disease, schizophrenia, autism, pain, and drug addiction. Elucidating the regulation and the molecular function of TMEM35a/NACHO will lead to new understanding of mechanisms that underlies the regulation of neurocognition, pain and addictive behavior. We collaborate extensively with faculty across campus in the pursuit of these research areas.
