Education:
- Eng.Sc.D., New York University
Biography:
Dr. John J. Metzner is a professor of computer engineering with
appointments in both the Computer Science and Engineering and
Electrical Engineering Departments. He received the B.E.E., M.E.E., and
Eng.Sc.D. degrees from New York University. Prior to joining Penn State
in 1986, he held faculty and research appointments at New York
University, Polytechnic University, Wayne State University, Oakland
University. He served a year as acting dean of the School of
Engineering and Computer Science at Oakland University, Rochester,
Michigan; and two years as acting director of the Computer Engineering
Program at Penn State.
In research, Dr. Metzner has devised various ARQ protocols for reliable
and efficient data communication, techniques for efficient comparison
of remote replicated data files, efficient acknowledgement protocols
for slotted ring networks, improved broadcast retransmission protocols,
methods for improved utilization of ALOHA and spread spectrum
multiaccess, and techniques for simpler and more effective error
correction. NSF has been the primary source of his research funding. He
is the author of Reliable Data Communications, Academic Press, 1998.
