Expertise

Silicon chip design, nano-electronics, sesnor design and fabrication.

Research description

Research interests include materials and devices for advanced silicon-based technologies, microfluidics systems in silicon for lab-on-chip applications, olfactory sensor design and integration and more recently has started to work with MEMs-based ultra-sonic transducers and sensors.

Douglas Buchanan (BSc ’81, MSc ’82, (Manitoba) PhD ’86 Durham UK)), P.Eng, FCAE (Fellow of the Canadian Academy of Engineering), spent 16 years (1986-2002) at IBM’s prestigious Thomas J. Watson Research Center, Yorktown Heights NY, where he worked on more than 10 generations of silicon technologies. Dr. Buchanan received several awards for technical innovation while at IBM. He has over 30 patents, over 100 peer-reviewed publications and over 100 international conference presentations.

Dr. Buchanan returned to Winnipeg in 2002 to take a position as professor in Electrical and Computer Engineering at the University of Manitoba. From 2003-2013, he held a Canada Research Chair in Microelectronic Materials. For 6 years he was the Associate head for graduate programs for ECE, running a program of some 200 graduate students. Dr. Buchanan spent one year as the Associate Dean - Research, and one year as Acting Dean for the Faculty of Engineering. He is currently a professor in Electrical and Computer Engineering at the University of Manitoba, Winnipeg, Canada. He is a Fellow of the Canadian Academy of Engineering, and a practicing Professional Engineer (P.Eng) working with clients throughout Canada and the United States on micro- and nanotechnology assessment and development, patent evaluation and expert witness evaluation.
