Curriculum Vitae
Email

Ryan Wisnesky obtained B.S. and M.S. degrees in mathematics and computer science from Stanford University and a Ph.D. in computer science from Harvard University, where he studied the design and implementation of provably correct software systems. While at IBM Research Almaden he contributed to the Clio, Orchid, and HIL projects. While a postdoctoral associate in the MIT department of mathematics, he developed the CQL query language for ontology manipulation based on category theory. He is currently exploring applications of CQL to safe AI as CTO of Conexus AI.

Current Activities

Project Elway seeks to replace legacy government and enterprise software applications with more sophisticated, next-generation mathematical components built on Kan extensions using CQL. As they "rejoice in light and give it back in hues more marvellous than before", the (Lord of the Rings) Silmarils reflect the universally generative nature of Kan extensions, and even in the darkness of the smallest data sets Kan extensions "of their own radiance shine like the stars".
