My research interest lies generally in the area of dietary patterns and chronic diseases including hypertension using controlled feeding study and lifestyle intervention designs.
Two major controlled feeding clinical trials that I was involved in include the Dietary Approaches to Stop Hypertension (DASH) Study and the Dietary Approaches to Stop Hypertension-Sodium (DASH-Sodium) Study. In addition to being an active member for the diet committee for DASH, I also function as the chair of the diet committee for the DASH-Sodium study. I am familiar with the development and operation of a controlled feeding study, which means the process of study design, development of questionnaire/forms for data collection/monitoring, development of quality assurance procedure, and data analysis.
I've also helped with the design and implementation of the lifestyle behavioral intervention program for the Hypertension Improvement Project (HIP), PREMIER clinical trial, Weight Loss Maintenance trial (WLM), ENCORE study, and the Cell Phone Intervention for You (CITY) trial.
Key words: Diet, controlled feeding study, mineral, blood pressure, nutrition.
