Jiahua received his B.Engr. degree from the Department of Electronic Engineering in Tsinghua University, Beijing, P.R. China. In September 2007, he joined the iQua group in the Department of Electrical and Computer Engineering at the University of Toronto, and completed his M.A.Sc. degree in September 2009. After receiving his PhD degree in Operations Management from the Rotman School of Management, University of Toronto, he is now an Assistant Professor at Imperial College London.
Jiahua earned a highly competitive spot to become the top ten among the over 90,000 students who took part in the College Entrance Examination in Shanghai in 2003. Then he got the chance to study in one of the best EE programs in China. His undergraduate studies mainly focused on the field of signal processing and communication systems and he got exceptional grades in his courses. As part of his undergraduate research experience, he worked on several projects, such as Digital circuit design in an RFID system , and a FPGA application project based on Xilinx Spartan-II. His bachelor thesis research was on the topic of pilot-symbol-aided channel estimation in OFDM systems.
In the master phase, his research interests are in the analysis and algorithm design in peer-assisted video-on-demand (VoD) systems. In particular, his research focuses on the quality and performance improvement in large-scale peer-assisted VoD systems.
Elias Kehdi, M.A.Sc., August 2009
Elias did his undergraduate program at the American University of Beirut, Lebanon, in the Department of Electrical and Computer Engineering. He received his B.Engr. degree in July 2007. In September 2007, he joined the iQua research group as a first year M.A.Sc. student at the University of Toronto. He completed his M.A.Sc. degree in August 2009. He now works at Bloomberg, Inc., in New York City.
In his undergraduate, he was placed on the dean’s honor list for every semester of his program. His studies focused on networking and signal processing. Elias presented his first paper on ECG monitoring system in the 6th FEA conference at the American University of Beirut and it was nominated for best creative achievement award. He worked as a research assistant under the supervision of Professor Mazen Saghir and Professor Zaher Dawy writing a journal about the same topic of his first paper.
Elias enjoys math problems, therefore he completed a minor in mathematics.
Xinyu Zhang, M.A.Sc., June 2007
Xinyu has graduated with a M.A.Sc. degree in June 2007 from the group, with a thesis titled “Drift: a Highly Condensed Emulation Framework for Mobile Nodes in Server Clusters.” He has previously studied in the Department of Electronic and Communications Engineering in the Harbin Institute of Technology, Harbin, China, and received his B.Eng. degree there with honors in July 2005. During his undergraduate years, Xinyu worked on various embedded system projects, such as “The Control Instrument for UCA Synthesizing Process,” “The Hypoids Pipeline Robot” (which won second prize in the Challenge Cup), “The Automobile Electronic Air-conditioner Based on FFMC-8L Microcontroller” and “The Platform for Automobile Rainwiper Testing.” His undergraduate thesis, which won an Excellent Thesis Award at the Harbin Institute of Technology, focused on the design patterns for microcontroller system software.
Xinyu has continued to work in the iQua group as a full-time Research Technician in the 2007-2008 academic year, before continuing to pursue his Ph.D. degree at the University of Michigan, under the supervision of Professor Kang Shin. His research interests during this period focused on the application of network coding in wireless networks, as well as the development and use of cluster-based emulation platforms for large-scale wireless networks. He is currently an tenured Associate Professor at the Department of Electrical and Computer Engineering, University of California San Diego.
Kevin Yuen, M.A.Sc., April 2006
Kevin received his M.A.Sc. degree in April 2006, officially becoming an iQua alumni. Kevin is co-supervised by Professor Ben Liang. He received the B.A.Sc. (Honours) degree in Computer Engineering from the University of Toronto in 2004. In his undergraduate design project, Kevin worked in a group to develop speculative parallelization for OpenMP compilers.
In Fall 2004, Kevin joined the iQua research group, and undertook challenging research problems in designing efficient distributed algorithms in wireless networks. Particularly, he was interested in applying optimization techniques to achieve energy-efficient data gathering in sensor networks. The objective was to find the optimal transmission structure on the network graph and the optimal rate allocation on the sensor nodes, while considering the effect of non-ideal data aggregation and wireless channel interference simultaneously. Kevin’s work has led to two conference papers (ICC and Networking 2006), as well as a journal paper, accepted with minor revisions to the IEEE Transactions on Vehicular Technology.
Kevin is now working at the IBM Toronto Laboratories in Markham, Ontario, as a software developer. He is currently in the process of applying for admission into a medical school, a dramatic change of course in his career.

M.A.Sc. thesis on “iFlow and Beyond: Bandwidth-Efficient and Delay-Aware Information Access in Mobile Ad Hoc Networks.” Protractor Software Inc., Toronto, Ontario.
Selwyn Yuen, M.A.Sc., January 2004
Selwyn graudated from the iQua research group and received his M.A.Sc. in January 2004. He received a B.A.Sc. degree in Systems Design Engineering from the University of Waterloo in 2002, graduating on the Dean’s Honour List. While at iQua, his research focus was to apply game theory and mechanism design to solve some interesting problems in networking, including ad hoc network formation and overlay multicast tree construction. His research on the latter problem also led to a IEEE INFOCOM 2005 paper and a journal paper that appeared in ACM/Kluwer Mobile Networks and Applications (MONET).
Since his graduation, Selwyn worked briefly as an a technology consultant before joining Scotia Capital as a credit derivatives associate, where his knowledge of modelling, optimizations, probability, and stochastic process were put to good use. He left Scotia Capital after two years, and joined Canada Pension Plan Investment Board as a Quantitative Analyst, in the area of portfolio management.
In his spare time, Selwyn enjoys playing badminton, travelling, and watching (GREAT!) movies.
