Steve has been active within the industry and academia. In industry, he joined IBM in the networking division in 1984 where he developed products, technology, and standards. He later moved into IBM's x86 server organization to focus on clustering with his areas of focus being systems architect, and eventually CTO, for BladeCenter and defining Infiniband as an initial cluster interconnect standard. He was designated a Distinguished Engineer during this time and engaged with teams across IBM, numerous technology partners, and customers to establish BladeCenter as an industry leading product.

He continued to develop next generation systems, technology and standards and was asked to join IBM Research Next Generation Computing team as chief systems architect, which included the development of a multicore processor for edge-of-network systems and applications for which he was designated an IBM Fellow. He continued to work in the areas of systems, networking, distributed storage, high availability, power-efficiency and acceleration (papers available), while part of both IBM Research and Systems until he retired June 2018 after 35 years.

Steve has been an adjunct professor at NC State since January 2000 continues to teach computer architecture and networking courses. In his spare time he enjoys the outdoors by hiking, running, biking, fishing, etc.
