BIO:

Ivana Ljubic is Full Professor in Operations Research at ESSEC. She teaches Decision Analysis, Optimal Decision Making, Operations Research (OR) and Business Mathematics in ESSEC MSc, PhD and Advanced Master programs. Prior to joining ESSEC in 2015, she was appointed at the University of Vienna. She also worked as Visiting Scholar/Professor at the Robert H. Smith School of Business at the University of Maryland, TU Dortmund, TU Berlin, Dauphine University, etc. From 2017 to 2019 she was Academic Director of the ESSEC EMBA program, and from 2017 to 2021 she was Academic Director of the ESSEC & Mannheim EMBA program. She has published numerous scientific articles in leading outlets and has been ranked since 2018 amongst the Top 5% of most successful business professors in Germany, Switzerland, and Austria according to various publication rankings. 

Ivana Ljubic has carried out consulting studies and industrial contracts for leading telecommunication providers in France and Austria. After completing her PhD in computer science, she also worked for 2 years as Financial Analyst for a Siemens spin-off (fin4cast), focusing on portfolio optimization.
