Between 1984 and 1991 he worked in R&D and in academia in Bucharest, designing and lecturing on microwave semiconductor devices and microwave integrated circuits.

    Between 1994 and 2000 he was with NORTEL NETWORKS in Ottawa where he was responsible for projects in high-frequency characterization and statistical scalable compact model development for Si, SiGe and III-V heterostructure devices. He spearheaded the modeling infrastructure development for, and was involved in the prototyping of wireless and broadband fiber optics transceivers in emerging semiconductor technologies.

    In April 2000 he co-founded Quake Technologies Inc. an Ottawa-area fabless semiconductor company focussing on the design and fabrication of 10 Gb/s and 40 Gb/s Physical Layer ICs. Quake was acquired by AMCC in 2006. As Chief Technology Officer at Quake he coordinated the access and characterization of Si, SiGe, GaAs and InP technologies, high-frequency package design and electro-optical interface integrated circuits development.

    In September 2002 he joined the Electrical and Computer Engineering Department at the University of Toronto where he is a full Professor. His research and teaching interests focus on the modelling, characterization and fabrication of nanoscale and atomic-scale electronic devices and technologies, and on design techniques and circuit topologies for mm-wave DSP, radio, radar and imaging ICs operating in the 50 to 1000-GHz range.
