Dr. Krzysztof Ostaszewski
Dr. Krzysztof Ostaszewski’s 1995 coauthored paper, “Fuzzy Techniques of Pattern Recognition in Risk and Claim Classification,” has been identified as the third most cited article in the Journal of Risk and Insurance, generally considered to be the leading journal worldwide in this area. Dr. Ostaszewski’s article was identified by Professors L.L. Colquitt, W. Ferguson, and D. Sommer in their presented paper “An Analysis of Risk, Insurance, and Actuarial Research: Citations from 2001-2005,” at the 2006 meeting of the Western Risk and Insurance Association in Santa Barbara CA.This analysis included an investigation all historical citations for the Journal of Risk and Insurance in this area. “Professor Ostaszewski's article is groundbreaking as it introduces an important and innovative technique into an area in which it had not been used before,” notes George Seelinger, Chair of the Mathematics Department. “When one writes a paper like this it is gratifying to see others build upon your work, and I am glad to see this happen to Dr. Ostaszewski.”

 

Fuzzy logic is a logical system introduced in 1965 by Professor Zadir Lofti where something may not be completely true or completely false, but somewhere in between—a statement may have a partial truth value. In the 1995 article, Dr. Ostaszewski and his co-author Richard Derring applied techniques derived from fuzzy logic to actuarial and insurance applications.

Ostaszewski has authored or co-authored two research monographs in mathematics and four research works in actuarial science. His research in mathematics and economics has been published in journals such as the Proceedings of the American Mathematical Society, Forum Mathematical, Journal of Mathematical Analysis and Applications, American Economic Review, and the Journal of Business. His research in actuarial science has appeared in the Journal of Risk and Insurance, the North American Actuarial Journal, Proceedings of the Casualty Actuarial Society, Journal of Insurance Issues, and other journals.
