He focused on the country's strategic needs,Constantly breaking the boundaries of scientific and technological innovation;He devoted himself to teaching and cultivating talents,Teachers and friends with students;It is the Beijing Institute of TechnologyAssociate Professor, School of Cyberspace SecurityGe Ke Ke。

Do not forget the original intention, adhere to the problem-oriented

"In order to achieve breakthrough results in the field of scientific research, continuous in-depth research is necessary。I do not blindly chase hot spots, but choose to work deeply in my field of expertise。”

Gai Keke has been engaged in scientific research in the field of cyberspace security for a long time, and his choice of career stems from his love for scientific research and his keen insight into the strategic needs of the country。"How can computer science and technology be better applied and developed in the field of cyberspace security, which needs to spend a lot of time to explore and verify?。”2018年，Geke Ke has studied, researched and worked overseas for more than 11 years，Firmly chose to return to the motherland，Joined the School of Computer Science, Beijing Institute of Technology (later joined the School of Cyberspace Security)，Align your interests with the needs of your country，We are committed to the security field of cyberspace, which is full of opportunities and challenges。

In recent years, Geke's scientific research direction has focused on blockchain, privacy computing, artificial intelligence security and other fields。"At present, blockchain technology is listed as a strategic forward-looking technology in China, and it is still in the initial stage of development, and it still faces many problems that need scientific research in terms of architecture, security, and application.。”目前，Gake proposed a number of blockchain scalability enhancement schemes，Including directed acyclic graph technology, fragment technology, special node construction technology and so on，For effective capacity expansion and performance improvement of blockchain systems;Hiding user identity and transaction data for different scenarios，Developed a privacy protection tool set for blockchain applications，And several blockchain-based platforms and tools that can be applied to electronic identity authentication, smart agriculture, etc。

After years of deep cultivation and accumulation, Geke has achieved fruitful results in scientific research。In 2022, he was selected into the National Young Talent Program, in the same period, he was selected into the "Annual List of Highly Cited Scholars in China" by Elsevier in 2022, and in the top 2% of the world's top scientists in 2021。Presided over more than 10 research projects such as key research projects of the Ministry of Science and Technology and projects of the National Natural Science Foundation;He has published more than 150 SCI/EI papers, including 10 ESI highly cited papers, and won 10 best paper awards in international conferences/journals;Applied for more than 50 patents 。

Seeking innovation in the midst of change, organic integration of teaching and scientific research

"The knowledge system of engineering is developing rapidly, so it is necessary to constantly absorb the latest scientific research results as support in teaching.。At the same time, teachers should have a solid teaching basic skills, scientific research and teaching better organic integration。Geke believes that teaching and scientific research are complementary, the experience and research results accumulated by teachers in teaching can provide valuable materials and ideas for scientific research, and at the same time, teachers can also apply scientific research results to teaching, so that the teaching content is more rich and practical。

"In addition to teaching students knowledge, it is more important to teach students how to learn and stimulate students' self-learning awareness.。Geke said that the current technological development in the computer field is rapid, so teaching can not be limited to textbooks, but to develop teaching plans according to the development of technology。

Geke served as the chair of the CNCC Key Technology Forum Unit for the Trusted Flow of Data across Domains 2023 and spoke at the forum

Teach by example and grow together with students

For students, Geke is also a teacher and a friend。In the laboratory, the morning meeting has become a custom, and any problems encountered by students in the process of scientific research can get timely and detailed guidance from Geke, from the research direction to the small word choice of the paper, Geke dutifully fulfilled his duties as a teacher。Mr. Fang Zhengkang, a graduate student of Grade 2022, followed Mr. Gai Keke during his undergraduate graduation，Benefit a lot，Therefore, I firmly believe that I will continue to follow Mr. Gai Keke in my postgraduate study，"At undergraduate level，I have a weak foundation in writing papers，Mr. Guy will teach me, hand by hand, the rules of academic language，That time，It is the fastest growing stage in my undergraduate study。Wei Yihang, a second-year doctor, studied geographic information as an undergraduate，Because of the switch to a new field of expertise，Wei Yihang just entered the research group of Geke Ke，Get into trouble from time to time，Gaike always gives timely guidance and care，很快，Wei Yihang students adapted to the learning rhythm of the new major，Becoming more and more adept at coping with challenges in study and research。

In addition to the problem of scientific research, how to choose the direction of career development is also a problem that many students feel confused。What qualities do different professions require？What is the life path of a "successful person"？"Only by anchoring goals all the way forward can we fully grasp the direction of life.。Looking back on his student days, Geke Ke gave his own answer to the students' life confusion。In Geke's view, confusion is normal, but should not stop, to in-depth thinking, personal research, personal experience, as soon as possible to clarify the goal, different career planning needs to have different abilities, after the selection of the goal, should be focused on improving ability, accumulate experience, so as to better achieve personal development。

For the education of the Party and the country, Gake always keeps in mind his original intention of "scientific research for the country's worries, innovation for the benefit of the people", and bravely shoulders the mission of science and technology power。Talking about his expectations for the future, Gai Keke said that he will continue to climb the peak of scientific research and train more outstanding talents for the school and society。
