Cadence Design Systems Inc. At Cadence, Rowen was CTO for the Intellectual Property Group.
Rowen shifted his focus back to entrepreneurship starting in 2016, calling his investment effort Cognite Ventures, LLC, an effort to invest in, advise and analyze start-ups in the deep learning domain. He also served as senior advisor to the SystemX Alliance industrial affiliates program at Stanford University for 2017. In October 2017, he cofounded BabbleLabs, Inc, a startup applying deep learning methods to speech processing.
BabbleLabs developed new speech enhancement and speech recognition methods, for deployment both in edge devices and cloud services. The role of improved voice communication became particularly crucial with the rise in work-from-home in 2020 triggered by the COVID-19 pandemic. BabbleLabs was acquired by Cisco Systems in October 2020, and the BabbleLabs team became part of the Cisco Webex conferencing and calling collaboration effort. Rowen became VP of Engineering for that voice technology group, and then VP of Engineering for all Collaboration AI.
Research
Rowen's research work at Stanford included participating in design of the first MIPS processor, the development of optimizing RISC compilers and creation of an early logic synthesis and layout system, for his PhD dissertation: ''SWAMI: A Flexible Logic Implementation System.''
He has written numerous articles on microprocessor architecture, system-on-chip design and design using application-specific processors. Rowen's book,
Engineering the Complex SoC was published in 2004.
