Liu Chi, born in 1984, is currently a professor and vice president of the School of Software, Beijing Institute of Technology. His main research interests are green Internet of Things, big data crowdfunding and processing technology. In 2006, he obtained a bachelor’s degree from the Department of Electronic Engineering in Tsinghua University, and then received a doctor’s degree from Imperial College London, England in 2010. He studied under Professor Kin K. Leung, an academician of the European Academy of Sciences. At the IEEE International Conference on Big Data Intelligence and Computing held in Auckland, New Zealand in August this year, Liu Chi and his team’s papers stood out among 139 submissions and won the only best paper award at this conference.
When he pushed open the office door of Liu Chi, vice president and professor of the School of Software, Beijing Institute of Technology, he faced the whiteboard and looked at the "tree diagrams" connected by circles. At the moment of turning to shake hands, the reporter saw a pair of "flashing" eyes, with his typical "baby face" after 80, and the appearance was difficult to associate with the "dean".
But as soon as he opens his mouth, his extremely fast speech speed and professional jargon such as "data transaction", "internet of things" and "smart city" make the listener have to turn on the brain "high-energy mode" to keep up.
The "eloquent" on the three-foot podium every day made him not shy about being interviewed. Before the reporter asked questions, he went straight to the point: "Come directly, anyway, it is similar to giving classes to students every day."
Light the listener, he is handy.
Lagging behind the elite? This is not the style of Xueba.
Liu Chi, a Ph.D. student from Imperial College in Britain and a background in Tsinghua Electronics, has been on the road to learning hegemony from beginning to end. Liu Chi, who was born in an engineer’s family in Xicheng District, Beijing, speaks pure Beijing dialect. Since elementary school, Liu Chi seems to be "hanging up" academically, and he rushed into the gate of Beijing No.8 Middle School with a near perfect score. He chose "Electronics" because he was afraid of learning economic management without "one skill". After entering Tsinghua, he finally tasted the feeling of being "surpassed".
As soon as I arrived at the university in 2002, I reported that Liu Chi’s classmates were the top students in all provinces and cities in China. Among his roommates, two provinces won the second place, and the other won the international Olympic gold medal. "I am the most ‘ Food ’ A "Liu Chi laughed.
After the first semester of freshman year, Liu Chi scored an average of about 84, ranking lower in grade. "This is not my style." The small universe of Xueba was ignited by competitive spirit. After a semester’s efforts, Liu Chi ranked in the top 20% of Tsinghua Electronics Department with more than 180 people and returned to Xueba list.
Even if he is a master of learning, his evaluation of himself is "I feel that my IQ is not high, but my emotional intelligence and personal perseverance are relatively strong."
In 2006, when he graduated, the University of Cambridge and Imperial College London both gave him an olive branch with full prizes. "I want to go to a bigger stage to see it." Liu Chi made an important choice in his life to enter Imperial College London to pursue a doctoral degree directly.
Hands-on experiment turns to "pulling out seedlings to encourage" ability improvement
Liu Chi, who doesn’t have a master’s degree until today, entered the Department of Electronic Engineering in Imperial College London, and the first project of studying PhD was the sixth framework project of the European Union — — A large-scale telecom joint research that brings together seven member units of the European Union to do Mesh intervention in wireless metropolitan area network.
Liu Chi, who won the full prize, needs to study in the Department of Electronic Engineering of Imperial College London for one year on the basis of graduation. From September 2006 to May 2007, Liu Chi was like a headless "fly" and couldn’t find the direction.
Liu Chi’s undergraduate studies in China are general knowledge, but he has no ability to solve cutting-edge scientific problems. His tutor, Kin K.Leung, a professor in the Department of Electronic Engineering in Imperial College London and an academician of the European Academy of Sciences, only pointed out a general direction for him, and most importantly, there were language obstacles.
One year, can there be any change? Xueba’s small universe was once again ignited by indomitable perseverance.
Within an hour on the way to school every day, Liu Chi spends all his time calling various customer service. "The customer service’s English is good and his attitude is good." In this way, his English has improved rapidly, but this does not mean professional success.
In nine months, Liu Chi’s weekly meeting with his tutor ended in failure. He insists on reading 10 professional papers every week and writing a report to his tutor. The response is: "If you can’t, I can’t support you anymore."
Liu Chi, who made up his mind not to learn and never return to China, made a major decision in May 2007 — — Stop reading articles and start practicing. When Liu Chi realized a network environment, he was suddenly enlightened, and at the same time he received the praise of his tutor for the first time: "What you did was right, very good!" "
However, the mentor’s expectation for Liu Chi does not stop there. Whether it is a paper or an academic conference, Kin K.Leung encourages Liu Chiduo to "brush the sense of existence". Time and time again, Liu Chiyu’s wings are gradually full.
Abandoning enterprises to teach and nurturing frontier scientific and technological dreams
After graduating from Ph.D. in September, 2010, Liu Chi successively entered German Telecom Research Institute (Berlin) and IBM China Research Institute as a postdoctoral researcher. After two and a half years, Liu Chi saw the application of scientific research results in industry and industry here, which benefited him a lot.
Liu Chi participated in the research and development of two projects at IBM: one was to design the "Internet of Things Application Technology Architecture" with the government of Qinhuangdao Development Zone, and the other was to develop a monitoring system for internal data traffic with Lufthansa. The full participation of these two projects has also accumulated first-line practical experience for Liu Chi’s future teaching. "I know what the industry is looking at and doing, so that I can better apply my research."
Liu Chi, who was still working at IBM in 2012, often said, "I have two jobs, one with money and the other without money; Those who have money go to work normally, and those who have no money make full use of all the rest time, write papers and do research. "
At that time, for a long time, the company’s research was aimed at the needs of the market, and Liu Chi could not do free technical exploration. And he has his own vision for technology. "I hope to achieve greater value in life, and the cutting-edge scientific and technological development was born in my hands." The cutting-edge science and technology may not produce value in two or three years.
So, in 2013, under the joint recommendation of Academician Wu Hequan, Vice President of China Academy of Engineering, and Professor Kin K.Leung, Liu Chi finally realized his ultimate dream of pursuing the forefront of technology and abandoned his enterprise to teach — — Step onto the platform of Beijing Institute of Technology.
When he just returned to campus as an associate professor, Liu Chi’s income was only "one-third" of the previous one, but "he finally had his own laboratory". What many people see as "trading at a loss" makes "technical coffee" Liu Chi feel full of happiness.
With a sense of well-being, Liu Chi, an "associate professor" born in 1980s, published more than ten SCI papers in the field of Internet of Things in just one year, and was awarded as a full professor by the school in 2014. Due to Liu Chi’s outstanding contribution to the transmission and processing of big data in the green Internet of Things, he was selected as the only candidate recommended by the national industrial and information system in 2015 as the "National Ministry of Human Resources and Social Security’s Support Program for High-level Overseas Students Returning to China" and was named as an advanced individual in the national "Twelfth Five-Year Plan" in 2016.
Side by side with the teacher from data beyond data
Liu Chi’s office is very simple: there is no sofa, except a desk, a conference table and several folding chairs. "It is just to facilitate the discussion of technical issues with students."
Liu Chi has been reluctant to erase the tree transmission structure diagram on the whiteboard, because it was the "spark" left by Kin K.Leung when he came to Beijing to discuss the new project in February this year.
"The content of the project is to use swarm intelligence perception and big data technology to conduct real-time dynamic monitoring of people flow and abnormal situations in places where large crowds gather, such as railway stations and airports." Liu Chi told reporters that the traditional monitoring of people flow is through cameras, but it is very difficult to achieve 360-degree coverage without dead ends in such a large place, so he proposed to use smart terminals carried by people. Under the condition that the camera observes a large area, the fine information provided by the intelligent terminal carried by people is used to further lock the possible abnormal situation.
The sensor data tree structure connected by circles on the whiteboard is about data collection and transmission analysis. One circle represents an intelligent terminal, and the information needs to be transmitted from one node to another. In the transmission process, the information needs to be preprocessed.
When discussing the technical details, they drew such a system architecture diagram, including how to collect, transmit and compress data, and finally how to analyze and process data in the cloud, which became the "baby" in Liu Chi’s office.
For the application and development of big data in the field of smart cities, Liu Chi said that big data is by no means a simple data analysis. The highest realm is to "come from data and surpass data" to achieve collaborative perception and intelligent decision-making of "people, machines and things".
Beijing Institute of Technology is only a few stops away from Zhongguancun Venture Street. As a post-80 s scholar, Liu Chi is not impetuous in Zhongguancun, but rigorous in science and engineering, and at the same time has the ability of orator’s talkativeness and logical self-consistency. More importantly, he respects and cherishes the podium.
