Professional Interests

 I had been focusing on the effect of high fat feeding during gestation, weaning and throughout the adulthood of mice. By using a murine model that is genetically predisposed to developing diabetes, I hope to learn more about the direct effect of a maternal high fat diet (HFD) on the offspring during gestation and early life. By examining epigenetic modifications in the setting of a high maternal high fat diet may provide an important link between the prenatal environment and increased susceptibility to adult disease.

 More recently I had been working on study examining the alteration of the DNA methylation and mRNA patterns of CD3+ cord blood cells. One of the goals was to identify differences in the DNA methylation profile in purified CD3+ T-cells between IUGR and AGA term newborns. Subpopulations of CD3+ T-cells such as CD4+ and CD8+ cells play pivotal roles in the development of obesity and inflammation. By identifying distinct CD3+ methylation patterns in IUGR male infants, I tried to show how these epigenomic alterations potentially affect the T-cell lineages that are related to inflammatory changes seen in metabolic syndrome. Secondary objective is to map these methylation profiles to known metabolic pathways/genes, thereby identifying possible significant genetic elements or biomarkers that could prove useful in future research and clinical studies.

  I have been currently working on developing a method for the efficient and systematic identification of the repertoire of receptor-ligand interactions relevant to human physiology, disease, and medicine using a cell-cell binding assay.
