Yuan Xie received his B.S. degree in electronic engineering from Tsinghua University, Beijing, in 1997, and his M.S. and Ph.D. degrees in electrical engineering from Princeton University in 1999 and 2002, respectively. He is currently a Professor in the Electrical and Computer Engineering department at the University of California at Santa Barbara. Before joining UCSB in Fall 2014, he was with the Pennsylvania State University from 2003 to 2014, and with IBM Microelectronic Division's Worldwide Design Center from 2002 to 2003. Prof. Xie is a recipient of the National Science Foundation Early Faculty (CAREER) award, the SRC Inventor Recognition Award, IBM Faculty Award, and several Best Paper Award and Best Paper Award Nominations at IEEE/ACM conferences. He has published more than 100 research papers in journals and refereed conference proceedings, in the area of EDA, computer architecture, VLSI circuit designs, and embedded systems. His current research projects include: three-dimensional integrated circuits (3D ICs) design, EDA, and architecture; emerging memory technologies; low power and thermal-aware design; reliable circuits and architectures; and embedded system synthesis. He is currently Associate Editor for ACM Journal of Emerging Technologies in Computing Systems ( JETC), IEEE Transactions on Very Large Scale Integration Systems (TVLSI), IEEE Transactions on Computer Aided Design of Integrated Circuits (TCAD), IEEE Design and Test of Computers, IET Computers and Digital Techniques (IET CDT). He is a Fellow of IEEE.Jishen Zhao received her B.S. and M.S. degrees from Zhejiang University, and Ph.D. degree from Pennsylvania State University. She is currently an Assistant Professor at the University of California, Santa Cruz. Her research interests include a broad range of computer architecture topics with an emphasis on memory systems, high-performance computing, and energy efficiency. She is also interested in electronic design automation and VLSI designfor three-dimensional integrated circuits and nonvolatile memories.
