Ivan completed his PhD at Université de Montréal in 2025, Computer Graphics Lab (Laboratoire d’informatique graphique, LIGUM), supervisor: Mikhail Bessmeltsev.

Ivan’s work is about automatic 2D and 3D asset creation for animation and design. His papers show that combining machine learning (computer vision, genAI) and geometric algorithms allows to build geometric representations with improved structural qualities.

Ivan completed his MSc cum laude in Applied Mathematics under Joint MSc program “InterMaths” between University of L’Aquila (Italy) and V.N.Karazin Kharkiv National University (Ukraine) in 2019. BSc in Mathematics was completed in 2017 at V.N.Karazin Kharkiv National University.
