Brief Bio

Guanlin Lu received his PhD degree in computer science in 2012. He is now working for EMC Data Domain. He worked with Prof. David H.C. Du . His research interests include storage system design and big data analysis. In particular, he is interested in applying statistical methods in storage system design.

Guanlin Lu got his B.S. degree in Computer Science from Huazhong University of Science and Technology, Wuhan, China in 2006. Following that, he obtained Master degree in Computer Science from University of Minnesota Twin Cities in 2009.


Guanlin Lu did an research internship at NEC Laboratories of America during summer 2010 at Princeton, New Jersey. 

Before that, Guanlin Lu worked as a software engineer intern in Symantec Storage Availability Management Group (SAMG) between June 2009 and December 2009, where he worked for cloud file system project.

Research Work

Guanlin Lu’s research work focuses on issues related to Data De-duplication field, involving adaptive chunking algorithm design, data pre-processing (e.g. clustering/classification) to support better performance of de-duplication. He is very interested in using machine learning techniques as well as clustering techniques to facilitate the performance of de-duplication process.

Engineering Work

During his intern with SAMG, he developed sets of custom Solaris MDB debug macros for each of Storage Cloud Data Server, Storage Could Meta Data Server and Storage Could Client modules to facilitate the core dump debugging & analysis. He also ported FiST based stackable file system from SunOS 5.7 to SunOS 5.10.
