Biography, Kai Keskinen After obtaining his Ph.D. at York University in Toronto, Kai worked at MPB Technologies in Montreal in the Electromagnetics group doing a variety of research in microwave remote sensing, radar cross-section measurements, Cepstral processing of Doppler radar data, airborne and shipborne antenna pattern measurement and predictions, and EMI/EMC work, primarily for military customers. With the downturn in defense funding at the end of the cold war, he moved to Nortel Networks to do EMI/EMC work on telecom systems and then shifted to Signal Integrity in Nortel’s Interconnect Group. After the telecom melt down, he started a small SI group at C-MAC Engineering. Following C-MAC’s acquisition by Solectron, Kai joined CoreSim, a design services company that specializes in Signal Integrity and Static timing analysis, board and chip level functional simulation, FPGA and ASIC retargets, and board design. CoreSim’s specialized techniques help external customers and CoreSim’s own designers to get their boards, FPGAs and ASICs right the first time. Kai is currently Engineering Manager for the Design Analysis group at CoreSim, which is now a Celestica Subsidiary. Kai has been using Allegro PCB SI, or SpecctraQuest as it was previously known, for over 7 years and previously he used UniSolve from UniCAD which was bought by Cadence.
