JC received his MPhil and PhD from the School of Public Health at the University of Hong Kong. During his graduate studies, he explored various topics in tobacco control, including adolescent smoking prevention, e-cigarettes, and tobacco industry denormalization. As a visiting doctoral student at the University of Florida, he used mathematical modeling to predict smoking prevalence in Hong Kong. At Columbia, he is mainly working on model-inference systems for the study of measles epidemics in China.   Outside of work, JC enjoys traveling with his wife across China and the world.

Haokun received her MS in biostatistics from the Mailman School of Public Health and her bachelor’s degree in Economics and Finance from the University of Iowa. She is interested in infectious disease modeling, and her most recent work includes an assessment of the impact of climate factors on influenza transmission in Hong Kong. With Dr. Yang, she is currently working on a project studying the interaction between different respiratory disease viruses at the population level.

I received my MPH in Chronic Disease Epidemiology at Mailman and my BA of Science in Biology at Northeastern University in Boston! During my time at Mailman, I explored a variety of topics including data harmonization and sematic mapping with the Children’s Health Exposure Analysis Resource (CHEAR) and exploring trends in depression and substance abuse among adolescents. I am currently working on identifying potential risk-factors associated with early-onset colorectal cancer. In my free time I like to run, try new food places around NYC, or play with my dog!
