He is responsible for Snapdragon roadmap planning, including setting competitive feature, schedule and cost targets for all Qualcomm Snapdragon products. He leads product management for all core AP technologies which include Artificial Intelligence, graphics, CPU, camera, video, audio and memory. His team is also responsible for market research and competitive analysis, and provides support to adjacent business units, including automotive, IoE, and computing.
Keith has worked in a number of engineering, marketing, and strategic planning roles within semiconductor companies for over 20 years. Before joining Qualcomm in 2008, he led several marketing and planning teams at Intel, working in their desktop, laptop and connectivity groups. He led teams responsible for the introduction of Intel’s first chipsets with integrated graphics, first Wi-Fi products and the launch of Intel’s first thin, light, and Wi-Fi connected laptops. Prior to Intel, he worked in several hardware and software design engineering roles at Texas Instruments in Dallas, Texas.
Kressin holds a Bachelor of Science in Electrical Engineering from the Milwaukee School of Engineering (MSOE), a Master of Science in Electrical Engineering from the University of Colorado and a Master of Business Administration from Cornell University. He taught his own three children math, with each entering high school fully prepared to take introductory Calculus during their Freshman year of high school. He authored “Understanding Mathematics: From Counting to Calculus” in 1997, which has helped tens of thousands of individuals better understand math. He currently lives with his family in San Diego, California.
