Jerzy Andrzej Filar
- Jerzy Andrzej Filar** (born August 30, 1949, in Warsaw, Żoliborz) is an Australian mathematician of Polish origin, His interests include operations research, stochastic modelling, [[game-theory]], Markov decision processes, perturbation theory, and environmental modelling.
Biography He received his early education at Primary School No. 1 in Warsaw. In 1964, he moved to Melbourne, Australia, where he attended Kew High School. In 1972, he obtained a B.Sc (Hons) degree in Mathematical Statistics from the University of Melbourne, followed by an M.Sc. in Statistics from Monash University in 1975, and a M.A. in Mathematics from University of Illinois Chicago in 1977. In 1980, he completed his PhD at the University of Illinois Chicago, defending his thesis titled Algorithms for Solving Undiscounted Stochastic Games. His doctoral advisor was T.E.S. Raghavan.
Academic career Since 1975, Jerzy A. Filar held various academic positions at institutions across Australia and the United States. He began his career as a Tutor at Monash University (1975–1976) before serving as a Visiting assistant professor at the University of Minnesota (1979–1980). He then held faculty positions at Johns Hopkins University (1980–1986) and the University of Maryland, Baltimore County (1986–1991), where he progressed from Associate to Full Professor.
Filar also served as a supervisor or co-supervisor in over thirty Ph.D. dissertations. including Editor-in-Chief of Environmental Modelling and Assessment (Springer), Honorary Theme Editor for "Mathematical Models" in UNESCO's Encyclopedia of Life Support Systems (EOLSS), and Associate Editor for multiple journals, such as Journal of Mathematical Analysis and Applications (Elsevier), Operations Research (INFORMS, 2011–2015), Dynamic Games and Applications (Springer), and Applicationes Mathematicae, a prestigious Polish journal founded by hugo-steinhaus. He also served as Co-editor of [[international-game-theory-review]]s (World Scientific) and contributed to the Annals of Dynamic Games (international-society-of-dynamic-games).
Research impacts Filar is an applied mathematician with research interests in operations research, stochastic modelling, optimization, game-theory, and environmental modelling. He supervised or co-supervised 31 PhD theses.
He authored 148 scholarly works, including articles, books, book chapters, and conference papers. Three books are:
Competitive Markov Decision Processes (Springer, 1997; co-authored with K. Vrieze) serves as a textbook on [[stochastic-game]]s and Markov decision processes, under the unifying concept of "Competitive Markov decision processes" for discrete-time models with finite number of states and actions. Analytic Perturbation Theory and Its Applications (SIAM, 2013; co-authored with K.E. Avrachenkov and P.G. Howlett) presents a unified analysis of algebraic systems dependent on small perturbation parameters, applied to fields such as Markov processes and optimization. Hamiltonian Cycle Problem and Markov Chains* (Springer, 2012; co-authored with V.S. Borkar, V. Ejov, and G.T. Nguyen). In game theory he introduced the concepts of switching controller stochastic game and games with incompetent players and explored a formulation of dynamic cooperative game. In operations research he pioneered embeddings of the Hamiltonian cycle problem in Markov decision processes. This linked to his more theoretical study of perturbation theory. the 2003 Fellow of the Australian Mathematical Society, and the 2005 Ren Potts Medal from the Australian Society for Operations Research. In 2007, he received the South Australian Science Excellence Award for Science Leadership and Management. In 2013, he was appointed to the Australian Research Council College of Experts.
