Summary

After receiving my medical degree, I completed my residency in Internal medicine in 2000. During my residency at Howard University, I was exposed to biomedical research and I became interested in pursuing clinical research for a career. However, for immigration reasons, I took a primary care position in a medically underserved rural area for a few years. From there, I became a research fellow in cardiovascular physiology at the Mayo Clinic. After spending two years doing clinical research, I completed a fellowship at the Mayo Clinic in sleep medicine and began to publish research reports. Subsequently, I then took a faculty position at the University of Minnesota in the Division of Pulmonary/Critical Care/Sleep Medicine. Meanwhile, I have continued to collaborate with Dr. Virend Somers at Mayo Clinic. Sleep medicine is a developing field, with ample opportunity for clinical research. Though obstructive sleep apnea’s (OSA) significant association with cardiovascular disease is well known, the pathophysiological mechanisms involved remain unclear. My plan is to pursue new biomarkers and other clinical indicators than will permit these pathophysiological mechanisms to become clearer. My aim is then to initiate a clinical research program that will use these biomarkers for early detection and, eventually, treatment of OSA.
