Celebrated mathematician Yuan Yuan returns to China after more than 20 years in US
Internationally renowned complex geometry researcher leaves New York to join Hangzhou’s ‘first class’ Westlake University as maths professor

After more than two decades in the United States, internationally recognised mathematician Yuan Yuan has returned to China as a full-time professor at Westlake University in Hangzhou.

He joined Westlake’s Institute for Theoretical Sciences in May, just months after being promoted to full professor at Syracuse University in New York, according to the university’s website.

Yuan is one of four mathematicians recruited by Westlake this summer after long careers in the US. The others are mathematical analysis expert Zhongwei Shen from the University of Kentucky, machine-learning statistician Yiyuan She from Florida State University, and applied and computational mathematician Hai Zhu from the Flatiron Institute in New York.

In an official statement, the leading researcher on complex geometry said he had long hoped to return to China, following in the footsteps of many scholars who had joined Westlake in recent years.

“Maths can really be done anywhere – all you need is paper, a pen and a computer with internet,” he said. “If you have colleagues who share your passion, that makes it even better.”

He added that when he was invited to give a talk at the university last year, he found the campus “first-class” and the people “lively and full of spirit”. As a new-type research-oriented university, Westlake naturally became his first choice, he said.

Yuan will continue his research in a field known as several complex variables, an advanced branch of mathematics that extends the idea of complex numbers into higher dimensions.

Complex numbers are essential to modern science and engineering, powering technologies from cellular networks to image processing.

Yuan said he was hooked when he first encountered complex numbers as an undergraduate at Peking University, where he belonged to the school’s “golden generation” of maths students that produced international stand-outs such as number theorist Yun Zhiwei at MIT and algebraic geometer Xu Chenyang at Princeton.

Yuan arrived in the US for higher studies in the mid-2000s. After earning his PhD in maths at Rutgers University under the supervision of Xiaojun Huang, a leading Chinese-American scholar in complex geometry, Yuan worked at Johns Hopkins before joining Syracuse University in 2013.

At Syracuse, he rose from assistant to associate and then full professor, winning a research grant from the Simons Foundation and an invitation to present at the International Congress of Chinese Mathematicians in Beijing, among others. He also taught more than 10 undergraduate and graduate courses during his 12 years there.

At Westlake, Yuan plans to continue advancing research in complex analysis while helping to grow China’s mathematics community. He will also take on teaching duties, with plans to train PhD students and attract strong undergraduates.

Next spring, he will offer a course on several complex variables to both doctoral and senior undergraduate students. “This way, they’ll have a chance to explore cutting-edge mathematics,” he said.

China deploys robot dogs in simulated moon conditions ahead of lunar mission

Peking University says it has developed two prototypes for exploring terrain considered ideal for establishing human bases

Chinese researchers are testing and training robotic dogs in preparation for future exploration beneath the moon’s surface, an area that is considered ideal for establishing human lunar bases.

According to a September 28 post on Peking University’s social media account, a team from the university’s school of computer science has developed two specialised robotic dogs for the exploration mission, and tested them in a cave in northeastern China.

Created by lava flows and located in a forest region near Jingbo Lake near the city of Mudanjiang in Heilongjiang province, the cave is “strikingly similar” to the lunar underground environment, according to the university post.

There, some sections suddenly narrow to a point that is impassable for research personnel, so the robotic dogs are deployed as “scouts” to reliably execute surveying tasks that the humans cannot easily accomplish.

Testing their performance in a “lunar-like lava tube environment” enabled researchers to advance the embodied intelligence technologies used in deep-space exploration, said Zhang Shanghang, a researcher at the university and the Beijing Academy of Artificial Intelligence, a non-profit AI research laboratory also known as Zhiyuan Institute.

Zhang, who led the development of the two customised robotic dogs, said these models could navigate autonomously, avoid obstacles, create maps and record high-precision 3D structures within caves.

Equipped with a lidar remote-sensing technology, the robots provided reliable spatial data for scientific research, he added.

One prototype draws inspiration from anteaters, a mammal that has evolved powerful forearms for digging. The device features a unique design combining a flexible robotic arm with a rigid mobile platform to focus on autonomous exploration and multifunctional operations in complex environments.

The other takes its name from a salamander, a type of amphibian. This prototype is a deformable, soft-wheeled robot adept at navigating challenging terrain and carrying out environmental reconnaissance.

Another Peking University scientist said the institution’s ultimate goal was to independently develop a deep-space exploration robot capable of undertaking future missions to celestial bodies such as the moon and Mars.

Advancing understanding of the underground lunar landscape with robots holds significant implications for using the moon in the future.

Lunar lava tubes or pipes – underground tunnels formed by lava flows – are considered the optimal location for establishing a crewed lunar base, offering protection from the intense radiation and extreme temperature fluctuations on the surface.

Li Jiaqi, a researcher at Peking University’s school of earth and space sciences, said temperature swings on the lunar surface could exceed 300 degrees Celsius between day and night, with lows reaching minus 183 degrees Celsius (minus 297.4 degrees Fahrenheit).

The extreme fluctuations make equipment highly susceptible to damage.

In contrast, lunar caves, where temperatures stayed relatively stable, would provide crucial support for the future deployment of exploration vehicles and even the building of crewed bases, he added.

Li said the underground volcanic lava pipes near Jingbo Lake were chosen because they were “one of the geological structures on Earth that most closely resembles the moon’s underground terrain”.

He added that the site was also China’s first teaching and practice base for the “simulated moon underground space” programme.

For similar reasons, teams from Western countries, including the United States and Spain, are actively developing and testing robotic dogs to explore lava tubes on the moon in moon-analogue environments on Earth.

China’s Chang’e 7 mission to the lunar south pole, expected to launch in about 2026, is to be equipped with a seismograph to study moonquakes and probe the lunar interior, according to scientists at the Chinese Academy of Sciences.

Working with Russia, China also plans to establish the International Lunar Research Station on the moon in the 2030s.
