       Overview 
       Overview
      Asthma varies widely among different racial and ethnic groups. In the U.S., asthma prevalence, morbidity and mortality are highest in Puerto Ricans, intermediate in European and African Americans, and lowest in Mexicans.

      My research interests center on determining why there are significant disparities in asthma prevalence, asthma severity and even drug responsiveness to common asthma medications among racial/ethnic populations in the U.S. Specifically, we are investigating the complex interaction of social, genetic and environmental factors and their impact on asthma and asthma-related traits. To this end, we created the largest minority pediatric study population in the U.S. to analyze gene-environment interactions related to asthma.

      I work in collaboration with a multi-disciplinary team of investigators from several Universities, which includes scientists with expertise in epidemiology, biostatistics, medicine, molecular and cell biology and genomics. Using tools from these disciplines, we perform comprehensive epidemiologic research (genetic, social and environmental) designed to untangle why populations differ in health and disease. We have leveraged the rich ancestry of racially mixed (admixed) populations to untangle complex gene-environment interactions for health and disease. We have developed specific expertise in population-based genetic studies in admixed populations. Most importantly, we are working to ensure that modern advances in research will benefit all populations.
