معرفی
Lesław Gajek is a Full Professor at Lodz University of Technology, where he works in The Division of Insurance and Capital Markets. He has established himself as a leading scholar in actuarial science and mathematical finance through his extensive academic career spanning over four decades.
Professor Gajek's research focuses on ruin theory, insurance risk modeling, pension plan management, and financial optimization. His methodological approach combines probability theory with practical financial applications, frequently employing mathematical techniques such as the Banach fixed-point theorem and regime-switching models. His work addresses complex problems in insolvency analysis, portfolio immunization, and interest rate risk management, making significant contributions to both theoretical frameworks and practical applications in the insurance sector.
Analysis of his recent publications (2013-2025) reveals an increasing sophistication in modeling approaches, with growing emphasis on multidimensional risk models, regime-switching environments, and applications of fixed-point theorems to insurance solvency problems. His research trajectory shows consistent development of rigorous mathematical frameworks for assessing and managing financial risk in insurance contexts.

Professor Gajek has supervised seven doctoral students to completion, including Łukasz Kuciński, Elżbieta Krajewska, and Marcin Rudź, contributing significantly to the development of actuarial science in Poland. His academic mentorship and extensive publication record across prestigious journals like Insurance: Mathematics & Economics and Journal of Risk demonstrate his sustained impact on the field.
