Personal HistoryI graduated from Virginia Polytechnic Institute with a BS in biology. Being interested in human genetics, I completed my Ph.D. training in human genetics and molecular biology at the Johns Hopkins University School of Medicine under the co-mentorship of Kirby Smith, PhD, and George Dover, MD. I worked on the genetics underlying fetal hemoglobin production as a possible way to provide better treatment for patients with sickle cell disease and beta-thalassemia. After spending 6 years working in Italy with Licinio Contu, M.D., again on genetic factors that modify clinical severity of beta thalassemia, I returned to the Baltimore in 2001. While working under Aravinda Chakravarti, Ph.D. I switched my research focus to the genetics of complex diseases such as hypertension. I became an assistant professor at UMB in 2005.
Research Interests* Genetics of hypertension and other complex disorders
* Pharmacogenetics of thiazide diuretics
* Bioinformatics tools for function prediction
* Regulatory elements (non-protein coding) in the human genome
