Zdjęcie prof. Tomasza Szulca

Professor Senior Tomasz Szulc was born in Wągrowiec (a small town near Poznan). He graduated from the Institute of Mathematics of Adam Mickiewicz University in 1975, writing his master's thesis "On the stability of solutions of difference equations". The supervisor of this work and his doctoral thesis was Prof. Ph.D. Jerzy Albrycht. He received his doctoral degree in 1982, defending his thesis entitled "Study of the stability of selected types of recursive equations", and the post-doctoral degree in 1992, presenting the thesis "Non-singularity characteristics and spectral properties of matrices".

Prof. Tomasz Szulc started working in 1975 at the Institute of Mathematics. In 1977, the Institute became part of the Faculty of Mathematics and Physics, from which the Faculty of Mathematics and Computer Science (WMI in polish) of Adam Mickiewicz University emerged in 1993. Prof. Tomasz Szulc has repeatedly received the Rector's or Dean's awards for scientific achievements.

In the years 1999-2002 prof. Szulc was the Head of the WMI Doctoral Study, in 2005-2008 he was the Vice-Dean for Student Affairs at WMI, and in 2006-2016 he was the Head of the Department of Numerical Methods also at WMI. He is currently a professor emeritus - has the status of a senior professor.

He has supervised several dozen master's students and 4 Ph.D. He is the author or co-author of nearly 50 publications. His research interests include applications of linear algebra, matrix theory and numerical linear algebra. He has cooperated and continues to cooperate with many world-famous specialists in the above-mentioned fields.

He is a member of the Editorial Board of Open Mathematics De Gruyter and has reviewed papers for various journals.

Prof. Tomasz Szulc delivered 4 plenary lectures, 3 lectures at the invitation of the conference organizers and presented papers at another 30 conferences. He is one of the originators of the cyclical conference devoted to matrix analysis and its applications, MATTRIAD, and has been the chairman of its Scientific Committee since the first edition (initially in the form of a workshop).  Conferences are held every two years, the eleventh in the series will take place in 2025 in Serbia.

In 2010, he received the Medal of the National Education Commission.
