Biography

Tom Anastasio received his Ph.D. from the University of Texas at Galveston in 1986. He is an associate professor in the U of I Department of Molecular and Integrative Physiology and a full-time faculty member in the Beckman Institute NeuroTech group. His field of professional interest is computational neuroscience.

Honors

James E. Heath Award for Excellence in Teaching, University of Illinois (1997-1998); James E. Beall II Memorial Award, University of Texas at Galveston (1986).

Research

Experimental neuroscience has produced a tremendous wealth of data concerning the neural substrates of behavior. Professor Anastasio's main goal in science is to create computational models of neural systems that synthesize and explain this data. His hope is that, in so doing, he can gain insight into how the nervous system works.

Anastasio is interested in modeling neural systems that are critical for perception and action. His two main interests are the processing of multisensory input by the superior colliculus, and the adaptive control of movement by the cerebellum. Because organisms experience the world not through one sense but through many, understanding multisensory processing is essential to understanding sensory perception. The superior colliculus is the first major site of multisensory convergence in the mammalian brain. Anastasio has developed models, based on probability theory and neural networks, which offer functional and mechanistic explanations for the multisensory response properties of neurons in the superior colliculus.

Because organisms exist in a changing world, understanding the adaptive control of movement is essential to understanding action. The cerebellum is the main site of adaptive movement control in the vertebrate brain. While the cerebellum seems simple in terms of its neural structure, data on the behavior of cerebellar neurons has been difficult to interpret. Current models present a conflicting picture of cerebellar function. Anastasio has developed new models, based on pattern correlation and neural network learning algorithms, which unify the various views of cerebellar adaptation.

An exciting avenue for collaborative work currently underway at the Institute involves the application of some of these models in the design of brain-like devices. Models of multisensory processing are being applied in the design of a self-aiming camera. Models of cerebellar adaptation could find application in robot control systems.

Anastasio's work fits into the themes of Biological Intelligence and Human-Computer Intelligent Interaction, since it involves a study of the properties of neurobiological computers.

His sources of funding include the NSF and ONR.
