Research Areas

My long-term interests have been in the general area of VLSI Circuits and Systems for high performance digital signal processors at the System-on-Chip (SOC) integration level. I have a specific interest in DSP and crypto computations, particularly associated with the representation and manipulation of numbers to perform the arithmetic. My interests also include the implementation of Neural Networks (both artificial and cellular); low power and low noise circuits for mixed-signal applications; new DSP algorithms; machine vision systems; video and image processing; DSP systems for hearing instruments; and recently, Micro Electro-Mechanical Systems (MEMs) and Quantum Cellular Automata (QCA). The ATIPS Laboratory has recently developed links with several groups in bio-engineering and medicine, and I am involved with several interdisciplinary projects including bio-analysis using dielectrophoresis and a low-power SoC bio-platform. These projects deal with the microsystem integration of sophisticated integrated circuits, and MEMS/Microfluidic devices. The work on QCA involves the development of a CAD tool that uses advanced simulation techniques, at the quantum mechanical level, to provide a platform for experimenting with this future technology.

External Affiliations:

Professor Hugh Williams, ICORE Chair in Cryptography (Department of Mathematics at the University of Calgary), has established CiSAC to bring together a multidisciplinary interest group in the area of information security and cryptograph. I am a member of CiSAC, and my associate, Dr. V.S. Dimitrov, is a member of the management committee.

I founded the first ATIPS laboratory in 2001 with funds from my iCORE research chair grant. The laboratory represents the UofC portal to the general services of the Canadian Microelectronics Corporation (CMC) and has over 70 users, including students, research associates, and faculty members, and also supports several graduate courses.

I was a member of the Electrical Engineering Grant Selection Committee from 1985-86, Vice-Chairman 1986-87 and Chairman, 1987-1988. I also chaired the Doctoral Prizes Committee for the years 1999-2001. I also served on the Faculty Women's Awards Committee from 1995-1998.

I served as an Associate Editor for IEEE Transactions on Computers, from 1994-1996, and have served on the editorial board of the Journal of VLSI Signal Processing since its founding in 1988. I was program chair for the 8th Great Lakes Conference on VLSI (in March, 1998), Program Chair for the Asilomar Conference on Signals, Systems and Computers in October, 1999, and General Chair for the 2003 Asilomar Conference. I acted as Program Co-chair for the 2000 Conference on Application Specific Array Processors, and was a Conference Co-chair for the 2002 and 2003 International Banff Workshop on System-on-Chip. I am on the organizing committee (and exhibits chair) of the 2004 International Symposium on Circuits and Systems, and have acted as a Program Co-chair for the SPIE annual conference on Advanced Signal Processing Algorithms, Architectures and Implementations since 1995. I have been a member of the Steering and Program Committee for the IEEE Symposium on Computer Arithmetic since 1993. I have also been guest editor for several special issues in technical journals including IEEE Transactions on Computers and the Journal of VLSI Signal Processing.

National Collaborations:

I was one of the 12 founding members of Micronet, a Federal Network of Centres of Excellence, and serve on both the Coordinating Committee and the Board of Directors.

I have been a member of CMC since 1985 (less than a year after it was founded). I served as Member Representative for the University of Windsor until 2000. I was also on the Board of Directors from 1989-93 (vice-chairman of the Board in 1993) and rejoined the Board in 2001.

Industry Collaboration:

I have had a long-term research interaction with DALSA Inc., and I helped pioneer the concept of in-camera defect detection in 1990. I have been a member of the Board of Directors of DALSA Inc., since 1992, and I currently serve on the Audit, Nominations and Technical Committees of the Board.

I have been working with Gennum Corporation since 1994. The initial work, which is still ongoing, was in the area of video signal processing (for broadcast quality TV signal processing). A more recent project has been in the area of novel low-power architectures for digital hearing instruments.

I have recently started an interaction with Micralyne Inc., in the area of MEMS and microfluidic devices for bio-devices. Micralyne are currently in the process of fabricating one of our recent microneedle array designs for blood sampling and drug delivery.

This is a recent collaboration with a Calgary corporation working in the area of crypto systems. I have been involved with the development of simulators and rapid prototyping platforms for their key establishment algorithms.
