Dr. Yao has authored over 60 peer-reviewed articles, received numerous research grants, and is a widely sought-after presenter for conferences in the United States and China.

Among the ways in which Dr. Yao most enjoys partnering with research clients is to help them answer critical questions about their house call program, their competitors, and the patients and communities they are serving. “Applied research, as we call it, is not really about getting something published in an academic journal,” says Dr. Yao. “It’s about – is the information useful? Is it helpful for improving care or expanding access to more patients who need care? We collect and analyze data, so we can deliver informative, actionable reports to our clients.”
