Tsinghua University’s ‘star’ twin scientists return to China from the US, Canada
- The sisters, whose study schedule turned them into social media stars, are teaching at major universities after completing their postdoctoral research
- Ma Donghan and Ma Dongxin each made important contributions in their respective fields while in North America
The sisters Ma Donghan and Ma Dongxin, who were born in Dalian in 1989, were top students at Tsinghua when they shot to fame after their study schedule was published online. Commenters were amazed at their daily 6am-1am routine.
The twins each received special scholarships from Tsinghua University in 2012, an honour awarded to the best five undergraduates each year. They remained at Tsinghua and earned their PhDs before heading overseas.
Elder sister Ma Donghan, who continued her studies at Purdue University in the US, has joined Dalian University of Technology in Liaoning province, northeastern China as a professor. Her research focuses on super-resolution microscopy.

Both women have made important contributions, with each of them responsible for developments that have advanced scientific understanding and led to improvements in their respective fields.
Super-resolution microscopes can find and track individual molecules, helping scientists to study cells in more detail than any regular microscope can achieve.
Donghan has published a dozen papers in high-profile journals, including Nature Methods, Nature Communications, ACS Sensors and the Science Citation Index.
By developing a new class of organic additives to fabricate perovskite films, Dongxin helped to develop record-performance LEDs, according to the MIT Technology Review’s selection committee for its Innovators Under 35 prize in 2022.

“My research abroad went smoothly, but I didn’t feel like I belonged. I was looking forward to coming back to China immediately after completing my studies,” Dongxin said, according to the Tsinghua website.
“Now as a teacher, I feel greater responsibilities, and I’m learning to better understand the courses and guide my students to tackle the most challenging scientific questions,” she said.
