Zhang Zhaohuan

Because of his outstanding school performance and academic potential, he was offered a lectureship by his alma mater upon graduation—a practice that is still in vogue in almost all universities in China when recruiting exceptional faculty members is difficult.

Prevention should be a primary strategy in controlling the spread of infectious diseases and improving the overall health of the general population of China.

In the height of the so-called "Great Leap Forward" era in 1958, an institutionalized frenzy with an ostensible yet unrealistic aim to overtake Britain in economic output, he was dispatched to the then newly established Chongqing Medical School (重庆医学院, currently Chongqing Medical University) to establish a new academic department, the Department of Preventive Medicine.

Besides his recognized excellence and contributions in biostatistics, his research interests also included other broadly defined areas of preventive medicine and public health.

The research projects he led, and the scientific publications he produced, were also in occupational epidemiology, women and children's health, geriatrics, infectious diseases such as measles and tuberculosis.

Zhang supervised many graduate students at Master or Ph.D level, who now work in universities, government agencies, and pharmaceutical companies in the United States, Canada, England, Australia and China.

Instead, he continued supervising graduate students, providing consultation service to various institutions across China, and collaborating in a number of research projects.
