Katarina Kostelić

Katarina Kostelić, Ph.D., serves as an Assistant Professor at the Faculty of Informatics in Pula, part of Juraj Dobrila University of Pula. She earned her doctorate in 2017 and maintains an active role in both undergraduate and graduate education, teaching courses including Social Network Analysis, Quantitative Methods of Business Decision Making, Operations Research, Statistics, and Business Analytics. Her office is located at room 13 (Negrijeva ulica 6; university campus).

Dr. Kostelić's research spans multiple interconnected domains, with a strong emphasis on game theory applications in decision-making processes, social network analysis, and cybersecurity. Her work frequently examines how awareness (or lack thereof) influences strategic interactions, with particular attention to emotional intelligence in organizational contexts. She has made significant contributions to understanding business networks, tourism economics, and statistical methodologies.

Analysis of her recent publications reveals a clear trajectory toward increasingly complex applications of game theory in cybersecurity contexts, alongside continued exploration of social networks in tourism and business environments. Her research demonstrates interdisciplinary reach, connecting computer science, economics, psychology, and management studies. The integration of neutrosophic sets in satisfaction measurement and the application of TOPSIS frameworks to cybersecurity risk assessment highlight her methodological innovation.

Dr. Kostelić serves in multiple editorial capacities, including Managing Editor of Applied Sciences and Business Economics, Member of the Editorial Board of Journal of Interdisciplinary Sciences, and Member of the Editorial Team for Symmetry. She has also contributed to the popularization of science through accessible explanations of strategic situations, game theory applications in cybersecurity, and business network dynamics.

Her research leadership is evident through projects including 'Analysis of social networks in Croatian tourism' (2019-2022), 'Role of emotions in strategic decision-making' (2019-2023), and contributions to international collaborations like MEGASFORA and SMART INNO. Dr. Kostelić has also developed educational resources, most notably her 2024 publication 'Introduction to R and RStudio,' supporting statistical education.
