Taejoong Chung is a post doc in the College of Computer and Information Science at Northeastern University. Taejoong earned his PhD in Computer Science from Seoul National University before joining CCIS. His research focuses on online social networks and using data to dig into social interactions; Internet security with a focus on SSL; and information-centric networking.

About Me

  • Hometown: Seoul, South Korea

What are the specific areas of your graduate education?

Computer networks and data science.

What are your research interests?

My research interests lie in internet (data) science, measurement, and information centric networking and can be grouped into the following:

  • Online social networks, where the goal is to understand social interactions, economical behaviors, crowd phenomena and information propagation with large-scale data.
  • Internet security (e.g., SSL/PKI), where the goal is to understand the ecosystem of SSL.
  • Information-centric networking, focusing on terabyte scale caching and routing in named data networking (NDN), which is one of Information Centric Networking architectures trying to address scalability issues.

What’s one problem you’d like to solve with your research / work?

Currently I’m focusing on understanding how SSL/PKI works in reality.

What aspect of what you do is most interesting?

There have been many security incidents related to SSL/PKI, including SSL certificates being compromised. They are also currently misused, for example through the use of invalid certificates. We expect to find some valuable insights through looking at the weakness of the current PKI.

What are your research or career goals, going forward?

I hope to be a good researcher who is eager to find and solve interesting problems, which are not limited to a specific domain.
