Biographical Sketch

Doug is President of Cayuga Wireless, an Wi-Fi technologies company that he co-founded in 2017. He had also been CEO and founder of Zenalyst, an artificial intelligence-driven financial analytics service, between 2016 to 2023.

From 2014-2017, Doug was a Visiting Researcher Scholar with the Dept. of Electrical Engineering and Computer Science at University of California, Berkeley, where he was with the Swarm Lab and Berkeley Wireless Research Center. Prior to that (2006-2014), he was a Technical Leader at Cisco Systems' Wireless Networking Business Unit and his work included R&D on Wi-Fi products and their standardizations. Later at Cisco, Doug was with Cisco Advanced Architecture and Research and investigated emerging paradigms like fog computing, data analytics, and Internet of Things. Before Cornell (1998-2000), he was a Software Engineer with the IBM Toronto Lab, where he developed enterprise-scaled applications for database access and distributed computing.

Doug is a Senior Member of IEEE and a licensed professional engineer (P.Eng.) of Ontario, Canada. He has received recognitions from the IEEE Standards Association on his contributions to the 802.11n and 802.11y wireless LAN standards.
