The application of the science of nutrition in disease prevention and health promotion stimulates me to encourage students to pursue a career path of teaching in various settings: academia and in the community at large.  When students use their nutrition knowledge to improve their lives and the lives of others, it is professionally rewarding to me to know that I have facilitated the process. Teaching and learning are parallel, for without one, the other can't be achieved. Research in nutritional sciences compliments teaching and is needed to keep information current for further dissemination.  Through research different interventions (basic and applied) can be hypothesized, tested and their effectiveness and impact evaluated.  My research initiatives focus on the impact of fatty acids, proteins and functional foods on coronary heart disease in the African American community. Additionally, the translation of this work via nutrition education to various community groups has proven to have an impact on awareness, education and moving people to action.


The integration of nutrition and disease pursuits in academia, research and community engagement to have impact not only locally, but regionally and nationally focused on reducing the coronary heart disease burden in minority populations.
