Starting in May 2014, I am a joint Computer Science PhD student at Disney Research and ETH Zurich in Switzerland, under the supervision of Prof. Thomas Gross, Alanson Sample, and Bob Sumner. My closest collaborator is Gergely Vakulya. Former colleagues of mine are Chouchang (Jack) Yang, Lito Kriara, Giorgio Corbellini, and Stefan Mangold. Between February-April 2018, I was visiting the Future Interfaces Group at CMU HCII in Pittsburgh (PA, USA), working with Chris Harrison, Amy Ogan, and Yuvraj Agarwal. Just before that, between October-December 2017, I was with the Wireless Systems group at Disney Research in Pittsburgh (PA, USA).

My research focus is body channel communication, human-computer interaction, future interfaces, embedded systems, wireless and human body network systems. Other research interests include system security, mobile computing, robotics, as well as software development methods and open source software.

I have a Bachelor's degree in Computer Engineering and Master's degree in Engineering Information Technology from University of Pannonia (Hungary). During the university years I participated in several research and development projects, and also worked as software engineer and embedded software developer at different companies. Besides using open source software, I contributed to the community with participation in Google Summer of Code in 2012. To explore the project management role in a development process, I had an internship at Ericsson Hungary in 2012. Based on my academic, professional and leadership performance I was awarded by the Google Anita Borg Scholarship in 2013.

Body Channel Communication (BCC) is a technique to pass information through the human body: an external modulated electric field is generated and coupled to the user, which then can be measured at any point of his/her body. Thus, the body acts as transmission medium in this communication system.

Several student projects are available, including (but not limited to):
  • performing channel characteristic measurements on the BCC channel
  • testbed development for BCC devices, e.g. online calibration for varying device sensitivity
  • prototype/application development to demonstrate BCC.

A wearable BCC prototype was developed by Disney Research, which can be used throughout the student projects.

Please contact me by e-mail if you are interested in any of these projects.

I had my Bachelor studies between 2006 and 2009 at University of Pannonia as Computer Engineer. I wrote my thesis about process network synthesis and optimization based on the P-graph methodology, in the research group led by Prof. Ferenc Friedler, under the supervision of Dr. István Heckl. I participated for several years in the Erdos Paul Program (known as Fasori Program) as Junior Researcher, and also as Junior Developer.

Between 2010 and 2012 I continued with Master studies at University of Pannonia as Engineering Information Technologist. As a member of the operations research group led by Prof. István Maros, we developed a novel LP solver based on the sparse simplex method called PanOpt.

In 2011, Márk Korondi and I won 1st prize together at the Hungarian National Student Conference in Artificial and Visual Intelligence section, with our work about a special edge decomposition problem, under the supervision of Dr. János Barát.

In 2011, Márk Korondi, Gergő Dóczi and I won 2nd place at the Ericsson Hungary C++ Programming Championship.

Before joining to ETH Zurich and Disney Research, between 2012 and 2014 I was a PhD student at Eotvos Lorand University with research focus on software analysis, under the supervision of Dr. Zoltán Porkoláb.
