In 1975, he and Donald R. Strong were the first to propose the theory of skototropism in an article in the journal Science (190: 804-806), which he later worked into his senior thesis at Florida State University (FSU), after conducting additional experiments. The thesis was expanded into his Ph.D. thesis at Harvard University. While at FSU, he earned undergraduate degrees in biology and chemistry.[1]

He is currently Professor of Zoology and Adjunct Professor of Computer Science at the University of Oklahoma in Norman. Previously, he was assistant professor and associate professor in the School of Life and Health Sciences at the University of Delaware from 1981 to 1998.[2] Tom Ray is also a former member of the International Core War Society.

Cultural references

In The Rise of Endymion, Dan Simmons's conclusion to his famous Hyperion Cantos sci-fi series, it is revealed by the character of Aenea that the TechnoCore originated from a human experiment in which computer programs were allowed to compete for resources (e.g. memory) and evolve accordingly. It is specified that the one responsible for it was Tom Ray, which possibly refers to the biologist's Tierra project.
