I have 20 years of experience, and specialize in the field of epidemiology, with specific knowledge in the areas of tuberculosis, HIV/AIDS, and public health. I have published on such topics as tuberculosis, HIV/AIDS, and infectious diseses. After the SARS outbreak 10 years ago, I was invited to Shandong China to lecture on Infectious Disease Control. Through my interaction with the Shandong Provincial government and Chinese CDC I have helped to establish a world renown TB control program and research center in Jinan, Shandong, China.
