His Ph.D. is in Theoretical Physics, which can be considered a form of applied mathematics. He has applied advanced mathematics extensively throughout his career.

He conducted applied research in applied Artificial Intelligence at Carnegie-Mellon from 1984 - 1990. Followed the curriculum of computer science and artificial intelligence. Attended many AI conferences. Subsequent projects at USC and Countrywide also involved AI.

He was responsible for the analysis and modeling of consumer responses for Countrywide's direct marketing of sub-prime mortgages.

This was the field of his Ph.D. thesis in theoretical physics. He also held post-docs at SUNY at Stony Brook and Carnegie-Mellon, in this field.

The automated property valuation system that he has developed uses the sales comparison approach as one of it's main methods of valuation.
