Three Viterbi Engineers Named AAAS Fellows

Michael Arbib, Terence Langdon and Aristides Requicha share honor from leading scientific society.

December 19, 2008 —

Three Viterbi School faculty members have been named fellows of the American Association for the Advancement of Science in recognition of their outstanding contributions in science and engineering.

Michael Arbib, Terence Langdon and Aristides Requicha of the USC Viterbi School of Engineering will be among 486 scientists honored in February at the Fellows Forum of the 2009 AAAS Annual Meeting in Chicago, Ill.

Michael Arbib

USC University Professor Michael Arbib, who is also the Fletcher Jones Professor of Computer Science in the Viterbi School,  was honored for “distinguished contributions to computational and cognitive neuroscience, development of schema theory and analyzing neural mechanisms of visuomotor coordination and their extension to language.”

Arbib holds joint faculty appointments in biological sciences, biomedical engineering, electrical engineering, neuroscience and psychology. He has developed computational models of the brains of frogs, rats, monkeys and humans and led the group that developed the Neural Simulation Language, a computational tool for modeling the interactions between neurons that eventually produce behavior and thought.

He has written extensively on the relationship between the brain and language and is tracing the evolutionary path that leads to the human language-ready brain. He also has written on the philosophical and theological implications of such research.

Materials scientist Terence Langdon was honored for “distinguished contributions to the field of materials science, especially in pioneering the processing and properties of ultra fine-grained and nanostructured materials.”

Langdon, who holds joint appointments in aerospace and mechanical engineering, materials science and earth sciences (the latter at USC College), leads a group seeking to engineer unusually fine-grained metals. Such materials exhibit far greater strength and toughness than some of their coarse-grained counterparts.

In particular, Langdon studies the phenomenon of superplasticity, a malleable state in metals similar to the softening of glass at high temperature. Working with his students, Langdon has greatly reduced the time required to shape metal parts using superplastic forming.

Aristides Requicha, professor of computer science, was honored for “pioneering contributions to research and education in solid modeling and nanorobotics.”

Requicha worked on intelligent engineering systems until the mid-1990s. He was a principal developer of the solid modeling technology that is now widely used in industry, where it has replaced traditional drafting and enabled large improvements in productivity and cost. More recently, Requicha’s group has built novel components for the nanorobots of the future and written programs for making arbitrary shapes with swarms of nanorobots.

Requicha is the founding director of the USC Viterbi Laboratory for Molecular Robotics and is the current editor in chief of the IEEE Transactions on Nanotechnology. In the spring, he was named co-recipient of the IEEE Robotics and Automation Society Pioneer Award, and last year he received the first Bezier award for his work on solid modeling.

The tradition of AAAS fellows began in 1874. Members are considered for the rank of fellow if nominated by the steering group of their respective sections, by three fellows or by the association’s chief executive officer. The AAAS council votes on the final list.

AAAS is the world’s largest general scientific society and publisher of the prestigious journal Science. The society was founded in 1848 and includes more than 250 affiliated societies and academies of science serving 10 million individuals.
