News:
08/21/2014: I am looking for graduate research assistance working on two possible projects: Project 1: Capacity characterization of practical network coding (reference 1, reference 2); and Project 2: Real-time network communications. (reference 1, reference 2). For application, please contact me by email and set up an appointment.
Research Interests:
Network coding: Graph-theoretic capacity characterization of inter-session network coding, algorithmic applications of network coding, Shannon capacity characterization of wireless network coding, network coded feedback, and network-coding protocol design and implementation.
Coding Theory: Iterative decoding algorithms, low-density parity-check (LDPC) codes, multi-phase multi-level codes, soft decoding algorithm for Reed-Solomon codes.
Information and Communication Theory: Multi-user detection using graph-based BP algorithms, dirty paper codes, and network information theory.
Signal Processing: turbo equalization and space time codes.
Control Theory: Optimal stopping theory.
Current Ph.D. students:
Jaemin Han (since 2009) working on network coding (particularly on algebraic or graph-theoretic characterization of intersession network coding.)
Wei-Cheng Kuo (since 2009) working on network coding (particularly on 1-hop intersession network coding with side information or with coded feedback.)
Imad Ahmad (since 2011) working on distributed storage networks with intelligent helper selection.
Former Ph.D. students:
Abdallah Khreishah (during 2007-2010, jointly advised with Prof. Ness B. Shroff) Abdallah is currently an assistant professor of Electrical & Computer Engineering, Newark College of Engineering, New Jersey Institute of Technology.
Gyu Bum Kyung (during 2006-2011) working on dirty paper coding, and error-prone structure identification of LDPC codes. Dr. Kyung is currently with Samsung Electronics.
Xiaohang Li (during 2007-2013, jointly advised with Prof. Xiaojun Lin) working on scheduling algorithms for time-sensitive network coded traffic.
Other Ph.D. students with whom I work or worked actively:
Sarah Sellke (during 2007-2009) Sarah is currently a visiting assistant professor of Department of Statistics, Purdue University.
Dimitrios Koutsonikolas (during 2008-2010) Dimitrios is currently an assistant professor of Computer Science and Engineering, University at Buffalo.
Donghoon Shin (since 2010).
