David Vallancourt is Senior Lecturer in Circuits and Systems. He received the BS (1981), MS (1983), and PhD (1987) degrees from Columbia, and was an Assistant Professor in the Electrical Engineering Department until joining Bell Labs in 1992. Dr. Vallancourt’s focus at Bell Labs and subsequent positions at Texas Instruments, Vitesse Semiconductor, and PMC-Sierra was analog and mixed-signal integrated circuit design for communications applications, for which he was awarded a dozen patents. In 2005 Dr. Vallancourt returned to Columbia, where he teaches introductory courses in electrical engineering for engineers and for non-engineers, electronics, laboratory courses including the senior “capstone” project lab, and the school-wide first year general engineering course The Art of Engineering. In 2007 Dr. Vallancourt received the Columbia SEAS Distinguished Faculty Teaching Award.
