I specialize in all aspects of assessing the broad spectrum of dietary exposures which provides the expertise to serve the University of Hawaiʻi Cancer Center as Director of the Nutrition Support Shared Resource. Examination of the relationships between diet and chronic disease outcomes, such as cancer and obesity, can aid the development of policies directed to improving dietary intakes in the population. Harnessing the capabilities of web-based, mobile-based, and image-based technology tools offer an opportunity to reach a wide audience via cost-effective, convenient, timely, and familiar channels. In collaboration with scientists in engineering at Purdue University, we have created the Technology Assisted Dietary Assessment (TADA) system that uses an integrated digital camera in a mobile telephone for taking images of foods. The TADA system consists of two main parts: the mobile food record (mFR) app and the backend system consisting of computation and database servers that employ image analysis to automatically identify foods and portion sizes. Researchers can access real-time data using a specially constructed web-application. The TADA system is the first of its kind to be developed as demonstrated by two patents. The system has been used successfully with diverse populations ranging in age from 1 to 65 years.
