Africa has a central role in evolutionary genetics as the birthplace of modern humans as well as a largest source of human diversity arising from total number of alleles, as well as unique alleles compared to non-African populations.
My research interests include the genetic discovery and population specific variation of non-coding genomic regions in Africa. Of particular interest are small-noncoding RNA (i.e. miRNA, siRNA) involved in the RNA interference pathway and diabetes management.
RNA interference or (RNAi) is a immune and gene regulatory pathway first identified in 1999 that utilizes small non-coding RNA fragments as triggers to either destroy invading RNA (i.e., viral or transposon derived) or to regulate endogenous gene expression. The implications of this research led to RNAi being the subject of the 2006 Nobel Prize in Medicine and to its use as a novel approach to manipulate gene expression in mammalian cells and organisms. Consequently, the ability to effectively knockdown a gene of interest by introducing small RNAs targeted against that gene has offered, for functional genetics, a wide variety of applications spanning almost all classes of organisms.
High coverage sequencing of African populations can provide information about variation in both exonic and RNAi–specific genes, unlocking novel human variation in these potentially functionally important regions.
Traditionally, hemoglobin A1c (HbA1c), fasting, and postprandial glucose were used to assess glycemic control and risk of complications in patients with diabetes. However, emerging evidence suggest that glucose variability may also play an important role in the development of microvascular complications and cardiovascular disease via several mechanisms including its role in oxidative stress and vascular pathology. Glucose control can vary substantially among individuals therefore genetic variation in the basal glucose control among populations is a question of interest.
