Tian Mei wanted to be a doctor since she was young, and now she has exceeded her childhood dream.

A clinical doctor and PhD instructor at the Second Affiliated Hospital of Zhejiang University School of Medicine, Tian and her team have created a series of innovative molecular imaging techniques, focusing on the basic research and clinical application of positron emission tomography (PET), which provides promising support for early disease detection, new drug development and stem cell research.

Born in Taiyuan, North China's Shanxi province, Tian, 44, enjoys international recognition. She is active in nuclear medicine and molecular imaging research, and has just come back from a meeting in Vienna held by the International Atomic Energy Agency.
