Ivan 🇺🇦 Puhachov





I am a PhD student at Université de Montréal, computer graphics lab (LIGUM), supervisor: Mikhail Bessmeltsev.

My work is about sketch and line drawing image processing, using mathematical modeling and machine learning. Take a look on my publications and projects for an overview.

I’ve completed my 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.
