Research Interests

Increases in adiposity elevate the risk of cardiovascular disease (CVD) morbidity and mortality.  However, there are important sex- and race-related variations in the definitions/measurements of obesity.  Moreover, the impact of adiposity on CVD outcomes may be modified by psycho-social factors, diet, physical activity and sleep patterns, among other factors.  The relationship between increased adiposity and CVD outcomes involves interplay between 'environmental' exposures (e.g., psychosocial stress), behaviors (e.g., diet, sleep quality/quantity, physical activity, etc.) and biological determinants (e.g., ancestral genetic variation).  My team and others have documented substantial racial differences in dietary and sleep habits, adipose tissue distribution, adipokine biomarker levels, and CVD risk factor profiles associated with obesity in African Americans (AA) compared to European Americans (EA).  These striking racial differences raise questions about the generalizability of CVD risk classifications developed in EA in predicting CVD outcomes in AA, and thus elicit specific studies to assess the complex relationship between various adipose tissue depots and other measures of subclinical disease, the related biomarkers and CVD endpoints.

I have a broad background in medicine, public health and epidemiology, with specific training and expertise in several key research areas.  My clinical background training is in metabolic diseases (in Romania and France).  My US-based training is in environmental and genetic toxicology (Yale University) as well as, during my doctoral and post-doctoral training at the University of North Carolina at Chapel Hill, in cardiovascular disease and nutritional epidemiology.  I am the principal investigator of several Jackson Heart Ancillary Studies that provided, among other biomarkers, measurements for adiponectin in all the JHS participants ("Developing predictive biomarkers for left ventricular hypertrophy in obese African Americans").  In these Jackson Heart Study ancillary investigations, we put in evidence 1) an inverse relationship between serum adiponectin and left ventricular (LV) mass in normotensive and non-insulin resistant participants (suggesting that adiponectin may interact with LV mass in mediating long term CVD risk), whereas serum adiponectin was directly associated with LV mass in participants with hypertension and insulin resistance; 2) that adiponectin was inversely associated with visceral adipose tissue and directly associated with abdominal subcutaneous adipose tissue; 3) that African American (AA) without obesity or insulin resistance exhibit a positive association between global individual European Americans (EA) ancestry and adiponectin levels; that is abolishing in the setting of increased adiposity; and 4) that adiponectin levels were directly associated (instead of inversely) with incident stroke among women, even after accounting for insulin resistance and hypertension status.  This suggests that visceral adiposity is a key regulatory mechanism governing the body's metabolism and a major source of key adipokines such as adiponectin.
