Ivana Geček Tuđen, PhD

Ivana Geček Tuđen, PhD, is a lecturer at the Department of Economics and Mathematics of The Zagreb School of Economics and Management, where she teaches mathematics and statistics courses.

In 2014, she received her PhD in mathematics (branch: probability theory and mathematical statistics) at the Faculty of Science – Department of Mathematics, University of Zagreb, and in 2020 she obtained the title of research associate. In her scientific work, she has dealt with random processes with special application in the risk theory and the application of optimization in machine learning problems. She is the author of several scientific papers in the field of random processes, she was a participant (and lecturer) at many foreign conferences and schools in the field of applied probability and statistics (with special emphasis on their economic application) and a participant in the Erasmus + program for lecturers as guest lecturer at TU Dresden.

She gained her work experience at the Faculty of Science – Department of Mathematics and the Faculty of Economics and Business, as well as the Faculty of Electrical Engineering and Computing, University of Zagreb.

She speaks English and German and programs in R, C, Python, Matlab, SQL, etc.
