Research Activities

Dr. Jia is working with Mingui Sun, PhD, mainly on two research projects funded by NIH. One project focuses on developing a novel leadless EEG system for point-of-care applications. Efforts to commercialize our prototype have been made and one company has shown interest in licensing our patent. The other project is to improve the hardware design and software algorithm of a wearable device, called eButton, for objective evaluation of diet, physical activity and lifestyle. We have collaborated with Baylor College of Medicine for a dietary study with children, which shows that eButton is a promising tool to minimize memory error related to child diet assessment, although other problems needs to be solved.
