Welcome!

Welcome to my personal page! Hope you can know more about me from this page or see my CV. Enjoy your stay!

I am graduating in this coming May and currently I am looking for a full-time position, either a postdoc, faculty or lab researcher.  If you are interested in me or have any recommendation, feel free to contact me at congduan.li@drexel.edu.  Thanks!

About me

At present, I am a Ph.D candidate in the Electrical and Computer Enginnering Department at Drexel University, Philadelphia, PA.

I am doing research under the guidance of Dr. John M. Walsh and Dr. Steven Weber in the Adaptive Signal Processing and Information Theory Research Group (ASPITRG) and Model and Analysis of Networks Lab (MAN-Lab).

Research

My research interests lie in information theory, network coding, source and channel coding, wireless communications, etc.

My current research topics include:
  1. Characterize the region of entropic vectors, from both outside (non-Shannon inequalities) and inside (matroid theory)
  2. Develope effective algorithms to use computers to prove rate regions for general multi-terminal networks, e.g., distributed storage systems, independent distributed source coding problems
  3. Characterize the properties of networks for which simple linear codes suffice for the entire rate region
  4. Develop network operations so that some important features of smaller networks can be preserved when extend them, or features of larger networks can be preserved when shrink them.
