I'm a PhD student in Computer Vision and Machine Learning, advised by Bastian Leibe in the Computer Vision Group of RWTH Aachen University in Germany.
My research focus is 3D human understanding with robotics application scenarios in mind.

For long, I have been fascinated by humanity's efforts to understand the mind both from an abstract point of view, and to create intelligent systems through real-life engineering practice (and especially where these two aspects meet). But foremost, I enjoy building things and understanding why they do or do not work. In my PhD research, I've been focusing on the detailed visual analysis of humans by machines, especially to allow robots and other intelligent systems to better collaborate and interact with people. This research has been partially funded by a scholarship grant from the Bosch Research Foundation.

Before joining as a PhD student at RWTH, I worked in the same group as a master student and wrote my thesis on crowd counting from images and video. Before that, I designed and analyzed medical image processing algorithms at the Medical Informatics Department of Uniklinik Aachen and published papers on eye redness measurement and wound imaging. During my German-language bachelor's at the Budapest University of Technology and Economics in Hungary, I specialized in Autonomous and Intelligent Systems. I wrote my bachelor thesis at Hungary's National Institute for Strategic Health Research on machine learning approaches for diagnosis classification. In an exchange semester and an internship at the Karlsruhe Institute of Technology (KIT), I focused on robotics, data mining and image processing.
