About me :
I received the M.S. degree in Applied Mathematics from Dnipropetrovsk National University, Ukraine in 2010, the M.S. degree in Cryptography and Information Security from University Bordeaux 1, France in 2012 and the Ph.D. degree in Computer Science from the University of Montpellier, France, in 2015.
Currently I am a Post-Doc researcher in University of La Rochelle, Laboratory L3i, France. I am working in SHADES project. The main topic of my work is text protection for integrity verification of hybrid documents (both numeric and printed documents).

Other activities :
Currently I am a part-time lecture in the IUT of La Rochelle.
The previous years, I was a part-time lecture in the University of Montpellier. I was teaching the practical courses on programming in C++ and MatLab applied to Image and Signal processing.
I am also a reviewer for Journal of Electronic Imaging.
