Early life and computer science work

Louis Hodes got his Bachelor of Science (B.S.) from the Polytechnic Institute of Brooklyn. He got his Doctor of Philosophy (Ph.D.) from the Massachusetts Institute of Technology (MIT) in 1962, under

, and under Marvin Minsky he did early research on visual pattern recognition in Lisp. He is also credited by some with the idea, and an initial implementation, of logic programming.


Cancer research

In 1966 he moved into cancer-related research, specifically at National Institutes of Health and later the National Cancer Institute where he turned his interest in visual pattern recognition to

applications. He also worked on efficient algorithms for screening chemical compounds for studying chemical carcinogenesis. His work on models of clustering for chemical compounds was pronounced a "milestone" by the Developmental Therapeutics Program of the National Cancer Institute, for "revolutioniz ngthe selection of compounds of interest by measuring the novelty of a chemical structure by comparing it to known compounds.""Milestone (1981): Hodes model for ranking small molecule structures (sic)", www.cancer.go
