Distinguished Alumni


Erik Riedel, Ph.D. is Senior Director of Technology & Architecture in the Cloud Infrastructure Group at EMC in Cambridge, MA. The group is working to build cloud storage technology for deployment in private and public clouds. Focus areas include scalability, robustness, metadata-informed policy, multi-tenancy and security.

Erik is a member of the SNIA Technical Council, helping to lead industry-wide education, technology promotion and standardization efforts.

Before joining EMC, Erik was Director of Interfaces & Architecture at Seagate Research in Pittsburgh, PA. The group he founded and led focussed on novel storage devices and systems with increased intelligence to optimize performance, improve security, improve reliability, and enable smarter organization of data. The technology targetted both large-scale enterprise storage clusters and ad-hoc collections of consumer and mobile storage devices working together. Previously, Erik was a researcher in the storage program at Hewlett-Packard Labs in Palo Alto, CA. He has authored and co-authored eleven granted patents and a number of pending patent applications, as well as numerous technical publications on a range of storage-related topics.

Erik holds B.S., M.S.E. and Ph.D. degrees from Carnegie Mellon University. His thesis work was on Active Disks as an extension to Network-Attached Secure Disks (NASD).


Howard Gobioff received his Ph.D. in Computer Science at Carnegie Mellon University in 1999. He was advised by Garth Gibson and Doug Tygar and was a key member of the CMU Parallel Data Lab. Howard's research interests were focused on large scale distributed systems, operating systems, and security. Before entering graduate school, Howard received a bachelor of science degree in computer science and mathematics from University of Maryland, College Park.

He joined Google when it was a 40-person startup, and became a key architect of the Google file system. Howard was involved in a variety of core Google projects, including the advertising system and the main crawling/indexing system. Howard believed Google is a company that could enable a simple computer scientist to fundamentally change the world by improving people's access to information.

Always fascinated with Japan and Japanese culture, in 2004 he launched Google’s Tokyo R&D center. Following that adventure, he decided to try a smaller city and relocated to Google's Manhattan office. Howard was always an active and loyal alumnus, visiting CMU every year to meet up with old friends, give lectures, and recruit people to join Google.



Hugo Patterson joined Data Domain in March 2002 and served as Chief Architect through December 2008 when his title was changed to Chief Technology Officer. From November 1999 to March 2002, he was the lead architect for data availability and management at NetApp, a provider of storage and data management solutions.

Hugo holds a B.A. in Mathematics from the University of Chicago, and an M.S. in Electrical Engineering from the University of Maryland. Hugo received his Ph.D. in Electrical and Computer Engineering from Carnegie Mellon University where he was a charter student in the PDL. He was advised by Garth Gibson and his Ph.D. research focused on informed prefetching and caching.
