My story

  • BSc in Computer Engineering, major in System Development

    I have started my studies at the Budapest University of Technology and Economics. My advisor was László Szirmay-Kalos, who picked me up and taught me the ropes of computer graphics when I knew nothing about this field, and guided me hand in hand towards our first Eurographics submission. I will be forever grateful to him for his teachings and inspiration.

  • MSc in Computer Engineering, major in Computer Science

    The journey continues onwards with a Computer Science major, which, for this university, can be thought of a mixture of a mathematician and an engineering curriculum. There’s still lots of programming and system design, accompanied by mathematical logic, hypergraphs and extremal combinatorics. In terms of teaching, the CS department was second to none.

  • PhD in Computer Graphics and Machine Learning

    I have started my PhD thesis abroad at the Vienna University of Technology with the supervision of Michael Wimmer, exploring the vast depths of modern functional analysis and its possible applications to the intersection of computer graphics and machine learning. This group is ranked as one of the bests in the field. The quality of life, working conditions, and being around so many happy and kind people was truly an incredible experience – without a doubt I spent the happiest years of my life here.

    If you are thinking about joining this group to start your PhD or as a PostDoc, and are wondering whether you will have a good time, think no further. I worked with Michael Wimmer, who is one of the best and kindest people I know, and I highly recommend joining his group.

Disney Research

After visiting our University, Wojciech Jarosz, head of Rendering group at Disney Research Zürich decided to invite me to for a 4-month project together with Ralf Habel and Steve Marschner under his supervision. It was an enlightening experience to join this prestigious group and see how they run this amazing research lab. The fact that I was chosen for this internship at Disney makes me feel warm and tingly inside. It is a dream come true. Thank you!
