Kazimierz Nikodem was born in 1953 in Wojkowice. He began his initial mathematical education at primary school and then secondary school in Wojkowice. He began his studies in mathematics in 1972 at the Faculty of Mathematics, Physics and Chemistry of the University of Silesia in Katowice. His master thesis was entitled "Wypukłe procesy stochastyczne" ("Convex Stochastic Processes") and written under the supervision of Professor Marek Kuczma. He defended it in 1977 obtaining a master's degree. Kazimierz Nikodem obtained a Doctoral Degree in Mathematical Sciences in 1981, defending his doctoral dissertation entitled "Wypukłe i kwadratowe procesy stochastyczne" ("Convex and Quadratic Stochastic Processes"), which was supervised by Professor Roman Ger. He obtained the post-doctoral degree (habilitation) in 1991. This title was awarded by the Polish Academy of Sciences in Warsaw, based on the defended post-doctoral thesis "K-convex and K-concave set-valued functions". Kazimierz Nikodem received the title of full professor from the President of the Republic of Poland Aleksander Kwasniewski in 2001. Privately, Kazimierz Nikodem is married to Jadwiga Nikodem, has two children and five grandchildren. Kazimierz Nikodem began his professional career in 1977 as an assistant at the Institute of Mathematics of the University of Silesia. Since 1984, he has been employed at the Department of Mathematics at the University of Bielsko-Biala, being Head of the Department between 1997 and 2023. Kazimierz Nikodem is the scientific father of four promoted doctors of mathematical sciences: Dr. hab. Szymon Wasowicz, Dr. Elzbieta Sadowska-Owczorz, Dr. Mirosław Adamek and Dr. Dawid Kotrys.
