To prospective students: Though I am always looking for briliant new graduate students to join my research group, I am sorry that I do not have time to respond to most of such inquiries.

We recently developed a computational approach to identify and prove information-theoretical limits, whose potential is yet to be fully explored. Here is a collection of results on several data storage and communication problems. Unsolicited contributions are welcome. If you have a burning question and think this approach may be helpful, please contact me.
To see the results on the SCITL page.
Quantcast QFS is designed to better accommodate the map-reduce framework by taking into account of the more recent hardware architecture. It originally supports on up to 3 parities in erasure code setting. In this project, we add more flexible erasure codes to allow more than 3 parities.
Implementation of a set of regenerating codes and locally repairable codes for distributed data storage.
