Brief Biography: Dr.Yu Hua was Postdoc Research Associate in McGill University in 2009 and Postdoc Research Fellow in University of Nebraska-Lincoln in 2010-2011. He obtained his B.E and Ph.D degrees from Wuhan University, respectively in 2001 and 2005. His research interests include cloud storage systems, non-volatile memory, big data analytics, artificial intelligence hardware infrastructure, etc. His papers have been published in major conferences and journals, including OSDI, FAST, MICRO, USENIX ATC, ACM SoCC, SC, HPDC, DAC. He serves for multiple international conferences, including FAST, ASPLOS, SOSP, USENIX ATC, SC, SoCC. He is the distinguished member of CCF, senior member of ACM and IEEE, and the member of USENIX. He has been appointed as the Distinguished Speaker of ACM and CCF. His Semi-hierarchical Semantic-aware Storage releases source codes of main components in GitHub for public use.

I'm looking for motivated graduate students and undergraduate interns. Please feel free to contact with me for details.
