William H. DeSmedt is an American author of science fiction. His debut novel, Singularity (2004), explores the 1908 Tunguska event and the speculative hypothesis that it was caused by a submicroscopic, primordial black hole. Although Singularity is a work of science fiction, in the tradition of Michael Crichton its premise is anchored in realworld science. Bill has worked in the capacity of programmer, system designer, and consultant to both startups and Fortune 50 companies, specializing in natural language processing, artificial intelligence, and knowledge engineering.
