Brief Introduction

I am an associate professor in School of Computer Science and Technology at Beijing Institute of Technology (BIT). While I have experience in various areas of computer architecture, networks and security, my current focus is the design and implementation of fast, secure and scalable networking systems, providing efficient and elegant solutions (algorithms, protocols, architectures and systems) for critical issues and applications. I serviced as CTO at Suntang Corp. from 2008 to 2009 where leading a team of hundreds and founded a Xilinx-BIT Joint Lab of High Performance Networking in 2009. I enjoy the research life due to its challenging and supreme feature. Meanwhile, since 2013, I am graduately aware of a talent in teaching, therefore my current work also includes MOOCs, big data in education and scholarship of teaching. I was a visiting scholar at Washington University in St.Louis, collaborated with Prof. Patrick Crowley, from Sep.2011 to Jul. 2013. I got a Ph.D. degree in Computer Science and Technology, supervised by Prof. Zhizhong Tang (汤志忠), Prof. Dongsheng Wang (汪东升) and Prof. Yibo Xue (薛一波), at Tsinghua University in 2008 and a B.Eng. degree with honor (as a member of 98'Elite Class) at Northeastern University, China, in 2002.

Overall Interests

Generally, my academic interests are three aspects. First, the Interenet Architecture in protocols, algorithms, architectures and systems for novel scenarios of applications, such as efficient data distribution, IoT and satellite networking, specifically in the areas of Named Data Networking (NDN) and Information-Centric Networking (ICN). Second, Network Covert Channel and Network Management, especially the conquer and defense in aspects of network traffic. Third, big data in Education, especially MOOC-based data analysis and high-precision anlysis of study behaviors. Both academic research and system development are under going in these areas.

Key Words: Netowrking, Security, Big Data, Internet, Protocols, Hardware, System, Algorithm

Named Data Networking (Internet architecture)

Considering the fundamental architecture of future Internet, I bet on the concept of information-centric networking (ICN). My viewpoint is clear that both TCP/IP and ICN may have their irreplaceable positions in future Internet, leaving the challenges of how and when. I was involved in this area since the very beginning of the Future Internet Architectures (FIAs) funded by NSF, as a key member working on named-based packet forwarding in the Named Data Networking (NDN) project. My interests include but not limited to the following.
  • named-based packet forwarding: algorithms, hardware and strategies
  • edge computing in ICN and cache locality
  • network security in ICN: attacking, defensing and methodology
  • incremental deployment of ICN in the world of IP
  • architecture design and implementation of content routers
  • satellite networking, Vehicle networking, IoT, and AR applications over ICN
We have a relatively large group, more than 10 faculties, working on ICN whose members come from both School of Computer Science & Technology and School of Information and Electornic in BIT. Our group has a lot experiences on, from the bottom up, signal processing, communications, networking, security and applications.

Network Covert Channel (security)

Network security is an amazing concept because of its endless defence-and-conquer feature. I have experiences for nearly twenty years on firewall, network intrusion detection, network behavior detection and more, acting as a researcher, a developer, and even a team leader (CTO) of hundreds of employees. The cross-cutting roles shape me an industrial and system perspective on security. My interests include but not limited to the following.
  • network covert channel: algorithms and applications
  • protocol analysis on mobile apps
  • privacy in the network traffic
  • security of satellite networking
  • network security systems: architecture, high-speed design and key techniques
Note that network security is a winner-take-all area, that is, the killer techniques really matter.

Big Data in Education (scholarship of teaching)

The conception of MOOC, massive online open course, has successfully shaped a new era of education integrated with information and communications technology (ICT), and thus an upcoming world with big data in education. From the perspective of scholarship of teaching, my interest is to understand learning behaviors by big data analytics, including but not limited to the following.
  • big data analytics in education
  • learning behaviors and habits
  • interactives in teaching and learning
  • data-inspired principles of learning
  • sytems of big data in education: architecture, design and key techniques
This topic is a joint work with ICourses, the biggest MOOC platform in China and even the world. We have implemented several fundamental systems in the past and now go to the academic part.

Past Projects and Interests

I have completed more than thirty projects as PI (principal investigator) for the past ten years. Some selected are listed as follows. (More is coming.)
  • EER: Energy Efficient Router, as PI, joint work with Dublin City University.
  • THUMP 107: RISC-compatible Microprocessor Design and Implementations, as one of key members, @Tsinghua.


Overall Interests

Computer science and technology is far beyond a tool to the human-being world, but an ideology that can shape the future in almost all aspects. My interest is to give every individuals (students) what they must know in mind about computer technology for their career in an easy way facilited with computer techonlogy. In a simple word, I teach computer techonlogy via computer technology. Confusing? Never to me. I give courses of programming, networking, security and other topics about computer in contents, while mostly assisted by the online web courses and systems. I believe that the online learning and even teaching may be critically important in the (near) future of higher education and life-long learning.
