Chinese scientist makes her mark in molecular imaging, Zhang Zefeng reports.

Seeing a new major that combines medicine and physics on the syllabus in the 1990s was a tipping point for then-medical graduate Tian Mei. She might have otherwise followed her parents' wish and become either a surgeon or a gynecologist.

"I felt I was born for nuclear medicine," Tian says. "I have always been fascinated by physics and eager to explore the unknown world."
