Wojciech M. (Walter) Kozlowski has been actively involved in research activities in mathematics and applications since the 1980s with a particular interest in functional analysis, fixed point theory and applications. A Fulbright scholar, an author of a monographic book “Modular Function Spaces” (Marcel Dekker 1988), a co-author of a monograph “Fixed Point Theory in Modular Spaces” (Springer 2015), and author of numerous scientific papers, he has held several academic posts at the universities around the world, currently as an Adjunct Associate Professor at the School of Mathematics and Statistics, University of New South Wales in Sydney. In parallel, he has been pursuing ICT professional career within leading global organizations. He has been active in the international professional organisations, including positions of a member of Linux Foundation Networking Governing Board, member of TheOpenGroup Certification Board, and Chair of the GSMA Open Infrastructure Group.
