Dennis began his industrial career at Texas Instruments in July 1969. He was elected TI Fellow in 1978 and, in 1980, he was appointed Vice President and Director of TI's Semiconductor Process and Design Center.
Between 1987 and 1997, Dennis was Vice President of Technology at Analog Devices. He returned to Texas Instruments in December 1997 as Vice-President of Si Technology Development.
In November 2007, Dennis became TI Chief Scientist and Visiting Scientist at MIT with responsibility for managing joint research between TI and MIT. In April 2010, he retired from TI, but he continues this role as a consultant to TI.
Dennis received his BS, MS and Ph.D. in Electrical Engineering from MIT in 1963, 1965 and 1968. He served twice on the Electrical Engineering faculty at MIT in 1968–1969 and 1974–1975. He is an IEEE Fellow and the recipient of the 1985 Herschel Award and the 1987 Jack A. Morton Award for his pioneering work on HgCdTe Infra-Red monolithic focal plane technology. In February 2000, Dennis was selected by the Electron Devices Society to receive the IEEE Third Millennium Medal.
His current research is in energy harvesting.
