Phd UC Berkeley, CS/AI. 9 years full-time in OSU CS, research on Probabilistic algorithms. Part time for another 9 years while engaged in startup activities related to my research, especially in the area of product recommendation for ecommerce. Retired from OSU in 2005 to pursue independent R&D in probabilistic methods (including Neural Networks) for dynamic target tracking and identification. My current research focuses on Large Language Model based architectures for modelling adaptive cognitive characters in ongoing environments.
