Dr. Gonzalez received the B.Sc. degree in Computer Science from the Instituto Tecnologico de Monterrey (1972, more than 50 years ago as of today) and the Ph.D. degree in Computer Science from the University of Minnesota, Minneapolis, (1975). He has been Professor of Computer Science at the Oklahoma University (1975-1976)), Penn State University (1976-1979), ITESM (1979-1980), University of Texas at Dallas (1980-1984) and the Univesity of California Santa Barbara (1984-2016) [includes Sabbatical Leave at Utrecht University (Jan 1990 - Jul 1990)]. On July 1st 2016 he became Professor Emeritus of Computer Science at the University of California, Sanat Barbara. In 2009 Professor Gonzalez became IASTED Fellow for his "contributions to Multicasting Dissemination Algotithms for Parallel and Distributed Computing, as well as for his decade long commitment to PDCS and IASTED". Professor Gonzalez research activity has concentrated on the development of efficient exact and approximation algorithms as well as computational complexity issues for problems in several disciplines.

Professor Gonzalez is currently working on
Multi-Message Multicasting
algorithms for networks. The is a fundamental problem that
arises when executing program in parallel computer systems.
Some applications include iterative methods for solving systems
of linear and non-linear equations, and most dynamic programming
procedures, etc. His research contributions include work in
message routing
and
parallel and distributed computing.
He has also developed efficient approximation algorithms for message dissemination problems
in hypercubes and communication networks when communication links or nodes fail.
He has also developed efficient approximation algorithms for deterministic scheduling problems. These problems have applications in manufacturing systems as well as in task assignment in real-time multiprocessor systems. He has developed efficient algorithms for preemptive and nonpreemptive scheduling problems in open, flow and job shops, as well as in identical, uniform and unrelated processor systems and grid systems.
Dr. Gonzalez has also investigated the complexity of generating exact and
approximate solutions to a set of
computational geometry
problems. Specifically, he has
developed some very interesting algorithms for partitioning, grouping
and covering problems. These are robust algorithms that
generalize to any number of dimensions.
These problems have applications in
computer-aided design, cluster analysis, etc.
Recently he has developed algorithms for corridor and
bridge problems.
In the area of computer-aided design of integrated circuits and systems, he developed efficient algorithms for component placement and wire routing for VLSI and MPCB systems. Specifically, he has developed efficient algorithms for channel, rectangle, and switchbox routing problems, via assignment, via placement, pin redistribution, and layer assignment for VLSI and MPCB systems.
Dr. Gonzalez has also developed
exact and approximation algorithms
for
graph problems,
code minimization, clustering,
two-dimensional map compression, generalized dictionaries,
statistical tests, page fault minimization, etc.
