Dr. Chui is a methodologist with expertise in research design, data analysis, and innovative approaches to data visualization. He brings this expertise to a variety of research projects, including the evaluation of physical activity and nutrition interventions for children, the examination of epidemics in the US including opioid overdoses and hepatitis C infections, and testing the effectiveness of food aid formulas to combat and prevent childhood wasting. His past work has been wide-ranging in terms of topics— from electrical signals in muscle fibers to US weather systems; scale—from 20 participants to more than 200 million medical billing records; and geography—from US health care delivery system evaluation to multi-country randomized controlled trials.
While in the training to become a food scientist in Hong Kong, Dr. Chui became interested in quantitative methods after working as a coordinator for a population base phone survey on nutrition knowledge and behavior. As a member of the Epidemiology and Biostatistics concentration, Dr. Chui strives to recreate the very inspiration he experienced in his course Intermediate Biostatistics. Seeking to foster professionalism in his students and preparing them for a variety of work settings, he incorporates real-life data into the coursework and emphasizes the importance of reproducible research in his teaching. In 2014, he was awarded the Tufts Teaching with Technology Award for using a wiki system in his class which acts as a collaboratively built and perpetually evolving knowledge base.
Dr. Chui had served as the Councilor of the APHA Aging and Public Health Section (2015–2017) and was the Program Planner of the same section for the 2016 and 2017 APHA annual meetings.
