Research Interest

My research program is aimed at understanding the epigenetic mechanisms that control developmental changes in susceptibility to neurological and metabolic disorders, as well as disease prevention. Epigenetic mechanisms refer to the molecular processes that regulate gene expression without altering the DNA sequence. Our research is focused on exploring the specific role of microRNAs (miRNAs) in epigenetic regulation. MiRNAs are small non-coding RNA molecules that work as master regulators of gene expression by binding to the mRNA of target genes and inhibiting their translation. This post-transcriptional regulation by miRNAs is crucial for many biological processes, including development, differentiation, and disease. Our research is concentrated on two primary areas. The first area examines the epigenetic effects that the Western diet and exercise have on the offspring's vulnerability to neurological and metabolic disorders. The second area investigates the role of miRNAs in the molecular mechanisms of neuronal injury and axon regeneration.

To understand how epigenetic changes affect susceptibility to neurodegeneration and metabolic dysfunction, we employ translational, genomic, and proteomic techniques. In addition, we make use of genetically modified Drosophila and mouse models.

Our goal is to gain a better understanding of the complex interplay between miRNAs and epigenetic mechanisms, and how these processes contribute to normal cellular function and disease pathogenesis. We anticipate that this investigation will provide insight into the fundamental functions of these molecular mechanisms and their potential as therapeutic targets.

Teaching Interest

I am enthusiastic about teaching neuroscience and cell physiology courses at the professional, graduate, and undergraduate levels. I developed and taught Neuroscience modules to medical, dental, PA, and nursing students at East Carolina University, Greenville, NC.
