Kris Sikorski Professor www.cs.utah.edu/~sikorski sikorski@cs.utah.edu

Professor Sikorski received his MS from the Department of Mathematics, Computer Science and Mechanics at the University of Warsaw, and his Ph.D. from the Department of Mathematics at the University of Utah. Professor Sikorski’s research interests are in the areas of scientific computation, computational complexity and numerical analysis, with special emphasis on Information Based Complexity. Of special interest are optimal algorithms for fixed points and nonlinear equations, optimal algorithms for signal reconstruction, forward and inverse problems in geophysics, combustion engineering, computational sensor networks, numerical verification and validation of nonlinear solvers as well as nonlinear optimization for inverse problems in urban modeling. Professor Sikorski was awarded First Degree Prize of the Secretary of Education of Poland (jointly with M. Kowalski and F. Stenger) for research leading to the publication of the monograph: Selected Topics in Approximation and Computation (1996). In 2001-2010 he received 7 Dean’s letters for excellence in teaching as well as best paper award in 2008. He published 2 research monographs with Oxford Press, 1 textbook and numerous papers in wide spread areas from theory of scientific computation and numerical analysis, algorithmic design, through software and hardware design. He is the founding Director (2001) of the Master of Science program in Computational Engineering and Science (www.ces.utah.edu) at the University of Utah. He currently directs the MS CES program. He held positions at universities in USA, Poland, Germany, and Italy. He chairs WG1.1 Research Group on Continuous Algorithms and Complexity/Foundations of Computer Science of the International Federation for Information Processing. He supervised 13 Ph.D. and 28 MS students. His students hold top positions in academia and industry.
