Currently, he is chief professor of Shanghai Mathematics Center, dean of Institute of Brain-like Intelligence Science and Technology, Dean of School of Big Data, Fudan University, and deputy director of Shanghai Brain Science and Brain-like Research Center.He has developed a series of mathematical, statistical and computer theories and methods in the field of computational neuroscience.Through the analysis and study of a large amount of data from neuroscience and brain diseases at different scales, he proposed a non-linear causal relationship method and theory, which can be applied to the diagnosis and treatment of depression and autism.He has made some achievements in the dynamics research of single neuron and neuron network, design and analysis of machine learning algorithm, and stochastic control theory.Mathematics, Physics, computer science, biology, materials, engineering, medicine, pharmacy, psychology, linguistics…What kind of scientific research brings together so many disciplines?At the Institute of Brain-like Intelligence Science and Technology of Fudan University (hereinafter referred to as the “Brain-like Institute”), such cross-topic research is the norm.As the first dean, Feng jianfeng is not only the chief professor of The Shanghai Mathematics Center, but also the dean of the School of Big Data of Fudan University.And his academic achievements published in the past two years are mostly related to diseases: sleep disorders, autism…”The human brain may seem small, but it consists of 86 billion working units (neurons)…”Feng Jianfeng, 58, talks about his research field with sparkling eyes.In 2015, Feng jianfeng was appointed as the first director of the Quasi-brain Research Institute of Fudan University.At that time, he solved a class of optimal stochastic control problems with the mathematical theory of neural computing of system development, and achieved excellent results, and became a well-known expert in the field of biological information in the world.In 1981, Feng was admitted to the mathematics department of Peking University.Like his classmates, he had lofty ideals in mathematical research and wanted to gather the bright pearl on the crown of mathematics.The teachings of ding Shisun, then dean of the mathematics department, gave feng, 17, a deeper understanding.”Teacher Ding wants us young people to keep our feet on the ground and be good people first before becoming scientists.”Feng jianfeng said.When he was young, Feng gradually turned his interest to applied mathematics. In his sophomore year, he began to audit the courses of the Biology department.For his doctoral thesis, he applied stochastic process theory to neural networks…Feng jianfeng has been using mathematical methods to study brain science for 30 years.He could have had a good career in industry or investment with his algorithmic skills, but Feng never wanted to switch industries.When Fudan University was preparing to set up a brain research institute, he, who had been leading a laboratory in a foreign university for many years, was the right choice for the pioneering team.”I do research driven by curiosity.” Today, the Institute has a faculty of 120, including research teams in cognitive neuroscience, computational systems biology, artificial intelligence algorithms and whole-brain computing.At the invitation of Feng Jianfeng, jia Tianye, a young scholar, joined the Fudan Institute of Quasi-brain Research.”Teacher Feng doesn’t talk much, but she always does what she says.His vision is to do indomitable, high-level scientific research.”Jia Tianye said.Feng said of himself, “For me, scientific research is the most enjoyable thing. I do research driven by curiosity.”In 2018, Feng’s team built a digital brain composed of 70 million pulsed neurons for the first time.Through the mathematical algorithm, the whole brain scale of the human brain billions of neurons function fine calculation simulation.Through computational simulation, the working mechanisms of brain sensation and perception, learning and memory, emotional decision-making and information processing are further analyzed, providing experimental and theoretical basis for the original breakthrough of artificial intelligence.By the end of 2021, a digital brain will have as many neurons as a real human brain.The prototype of the digital brain is Feng Jianfeng himself.Feng Jianfeng assistant is introduced, the “model” the brain is not good, when the schedule of “three days” to the top of the day people Feng Jianfeng, often need to accurately calculate the time, from fudan university handan campus drive to pudong zhangjiang international brain imaging center, undergo scans on magnetic resonance imaging equipment, monitoring brain activity, for the digital brain with the prototype data.”Feng didn’t complain about being in a high-field environment for more than an hour.””Said Xie Chao, one of his doctoral students.Feng has also been insisting on discussion classes three to four times a week.Monday and Thursday afternoon is “whole brain computing” research group;On Tuesday afternoon, the brain neuroscience team.Occasionally, due to conflicts with other work, the discussion class would be moved to the evening. Even when Feng was on a business trip, he would attend by video and never cancel.All of us have to speak, young researchers have to report research progress and cutting-edge academic information, and students have to give summaries and opinions on reading articles and books assigned by their tutors.”Get to the point.Summarize the 50 pages you’ve read into three sentences and tell me!”Feng unceremoniously shut down a PhD student’s presentation.Students are most afraid to discuss feng Jianfeng in class.”Don’t assume that he’s too busy to remember your report, that he’s going to keep asking, ‘What are you doing with this research?The night the seminar ended was our real weekend.”Xie Chao said.”Cross-disciplinary talent growth is much more difficult than traditional disciplines.To make a breakthrough, we must resist all kinds of interference and persevere.”In Feng jianfeng’s opinion, scientific research should be driven by interest, talent and “hard work”.Only by building a platform, expanding vision and increasing pressure, can the institute develop itself into a cutting-edge research and technological innovation center with global influence, so that young people can grow up quickly.”We should not only focus on long-term goals, but also pay attention to some ‘hot’ issues.” Feng Jianfeng often says “fun” and “interesting” when talking about scientific research.Colleagues and students also said that he often had an unrestrained research inspiration.Feng Jianfeng has his own understanding of the saying: “Scientific research must be cold and lonely, and it is necessary to have long-term research goals.However, researchers should not have only one scientific problem in mind, but should always have multiple topics and goals in the short term (hot), medium term (warm), and long term (cold).Stay focused on long-term goals, but also focus on ‘hot’ issues.”In recent years, artificial intelligence technology is hot, but there is still a long way to go to crack the working mechanism of the human brain and realize the computer simulation of brain work.For example, the Zhangjiang International Brain Bank, which the Institute is building, has more than 520,000 internationally shared databases, but it is still accumulating data in some important areas of brain science.The research institute is also using data and algorithms to refine theoretical models, study neurological diseases through new approaches, and seek ways to intervene and treat them.”Teacher Feng led the team and contacted many hospitals and research institutions to collect clinical needs.The work is tiring and difficult, but rewarding.”Vice president Xie Xiaohua said.”We collected sleep brain data from about 170,000 people and found that the longer adolescents slept, the better their brains developed…”In July 2021, feng jianfeng’s research report on healthy sleep at the World Artificial Intelligence Conference was read 460 million times.This made him proud and he became more enthusiastic about science popularization.Now, he’s working on a popular science book about the brain and brain-like…The schedule is full by the hour, and I am still Posting wechat articles and tracking research progress at 11 PM.With perfect time management and strict self-discipline, Feng jianfeng can quickly figure out the “best route” even when walking across the campus, saving more time than others.Feng jianfeng has many hobbies, including tennis, badminton, swimming, mountaineering and many other sports.He keeps an hour of physical exercise a day all the year round.Even between meetings, he would change into his sneakers and run laps around campus…Interdisciplinary integration of high-level scientific research diversification, crossover, integration…Such words are becoming more and more common in life.In science, too, there is a group of scientists who span many disciplines.Especially with the help of new technologies and devices such as big data, super computing power and photonic devices, many traditional academic paradigms have also ushered in new opportunities for innovation and development.Technical equipment alone is not enough. To truly achieve interdisciplinary integration, a large number of talents with solid academic foundations and good at breaking through the boundaries of traditional knowledge are needed.Today’s education, scientific research and personnel training should attach great importance to this.Of course, interdisciplinary research is only a means. The goal of interdisciplinary research is to do scientific research with feelings that is conducive to economic and social development and the improvement of people’s living standards.On Feng Jianfeng, this kind of family and country feelings are fully reflected.No matter how scientific research and innovation may change, it is this kind of mission and responsibility that will support researchers to go further.Source: People’s Daily
