I am a young researcher and educator working on applications of computer and machine vision in mechatronic systems using modern ICT such as microcomputers, cloud, computational intelligence, etc. My current focus is on the use of deep learning in practical applications for Industry 4.0 such as visual quality control. I am also involved in modelling and simulation of production processes in manufacturing. I have experience in leading research teams in domestic projects. I have been responsible for 2 projects of the Young Researchers Support Programme. I was in the position of deputy head of the KEGA project, which ended with an excellent evaluation and the societal benefit of its results was stated. Currently, I am also the deputy project leader of a KEGA project. In addition to my professional interests, I am also interested in multimedia, film, video, photography and 3D graphics.
