Guérin was installed Oct. 8 in Stephen F. & Camilla T. Brauer Hall.

The professorship was established in 1988 by a university alumnus and his wife in the “hope that engineering education and research may be made more effective in present years, as well as years to come.”

Guérin is an international leader in the field of computer networking, both for his major research contributions and his dedication to serving the community. He is widely recognized for his contributions to understanding the fundamentals of data network design and how networks can be designed to provide desired quality of service guarantees. His work was among the earliest in this area and is credited with laying the foundation for later work. He also made early contributions in wireless and cellular networks.

“I am pleased to have the privilege of installing Roch Guérin as the Welge Professor at the School of Engineering & Applied Science,” says Ralph S. Quatrano, dean and the Spencer T. Olin Professor. “His strong national and international reputation for his research and experience, as well as his commitment to outstanding education, makes him an excellent representative of this professorship. We are grateful to the Welges for their generosity.”

Harold Brinton Welge earned a bachelor’s degree in architectural engineering in 1930 and a master’s degree in structural engineering in 1933, both from the university. He began his career with the City of St. Louis Department of Public Utilities, then left in 1941 to join Procter & Gamble, where he spent more than 26 years as a mechanical engineer and administrator in St. Louis and Cincinnati before returning to work for the St. Louis Water Division. He retired in 1979 and died in 1990.

Adelaide Guinn Welge earned a bachelor’s degree in general science and a master’s degree in mathematics, both from the University of Pittsburgh. She worked as a buyer for a major department store in Pittsburgh before marrying Mr. Welge in 1939. Her career took her on business trips to Europe, where she became interested in fashion design and ornithology. She died in 1996.

The Welges traveled extensively and generously supported community organizations and scholarships, including the Conway B. Briscoe Scholarship at Washington University, named in honor of Mr. Welge’s friend at the St. Louis Water Division, as well as scholarships for students in Blair County, Pa., and elsewhere.

The Department of Computer Science & Engineering has an exceptional reputation for interdisciplinary education, innovative research and exceptional faculty. One-third of its faculty has earned the National Science Foundation's prestigious Faculty Early Career Development (CAREER) Award. With more than $5 million in annual research expenditures, together with the impact of its technology on industry and research, the placement of graduates and its close connection to the School of Medicine, the department has established an unmatched environment to train the next generation of leaders in computer science and engineering.

Guérin joined Washington University July 1 from the University of Pennsylvania, where he was the Alfred Fitler Moore Professor of Telecommunications Networks and professor of electrical and systems engineering and computer and information science. From 2001-04, Guérin was on leave from Penn to start Ipsum Networks, which pioneered the concept of route analytics for managing IP networks.

Prior to joining the faculty at Penn, he was in a variety of technical and management positions at the IBM T.J. Watson Research Center in Yorktown Heights, N.Y.

A Paris native, Guérin earned master’s and doctoral degrees in electrical engineering from the California Institute of Technology (CalTech) and a bachelor’s degree from ENST Paris.

He received the IEEE (Institute of Electrical and Electronics Engineers) INFOCOM Achievement Award and the IEEE INFOCOM Best Paper Award in 2010; the IEEE Technical Committee on Computer Communications (TCCC) Outstanding Service Award in 2009 and was elected an IEEE Fellow in January 2001. He was elected an ACM (Association for Computing Machinery) Fellow in 2006, and received the IBM Outstanding Innovation Award in 1994.

He has published research in a variety of journals and served on advisory boards of international telecommunications companies. He is now on the scientific advisory board of Simula Research Laboratory in Norway.

The professorship was previously held by former department chair Gruia-Catalin Roman.
