2013 – (2016)
Doctoral student in Statistical Physics
Supervisor: Dr. Gergely Palla
Picturask: In this project we studied the emergence of hierarchy in a homogenous group of humans, through an on-line game. As the owner of the project I implemented the software facing the subjects, and also analyzed and summarized the results.
Predket: An on-line prediction market. I was responsible for the implementation of the software, and the analysis of the results.
2011 – 2012
Student, Computational Physics
Class-first supervised learning algorithm: For a class assignment, we had to select and implement a supervised learning application. The goal was to approximate the distance of stars based on their spectra.
Thesis: For my thesis I've implemented an algorithm to find overlapping modules in a network, based on simulated annealing.
2006 – 2010
Thesis: My thesis was about the optimal usage of a cold neutron selector used in KFKI, whereas I used the Simplex method to infer the exact pixel sensitivities.
2002 – 2006
Mathematics and English
Although this might be irrelevant, but I loved going there.


2013 – 2016
Supervisor in Modern Physics Laboratory
During holography, infrared spectroscopy and spectrophotometry labs my responsibility was to prepare and conduct the measurements, and to grade the students.
2013 – 2016
Teaching assistant in Statistics and Probability Theory
I helped the preparation and grading of exams and assignments. I also did complementary tutoring. In 2016 I was responsible to teach the complete material to a foreign student.

Work experience

Assistant research fellow
Forecasting patient disease history based on real historical data. In this project I had to process a big database (more, than 10 GB) and utilize it for the creation of statistical models.
2012 – 2013
Developer / Analyst
My role was to develop and apply network-based data mining techniques, and create complementary interactive or static visualizations. Our customers had various backgrounds, like healthcare, media or politics.
2012 – 2013
Developer intern
Participated in the autumn, spring and summer internship programs as Java developer. I created a Drools based (a business rule management tool) application for intelligent database migration. During the summer program I was developing a Flex-based web application for internal usage.
I have been the treasurer of the association for the first two years. Later I contributed as a web developer to the association’s work. I helped organizing educational and social programs, such as competitions and two visits to CERN. I also contributed in organizing ICPS (International Conference for Physics Students) which took place in Budapest, during the summer of 2011.
Developer intern
Through the summer and autumn internship program I worked as a Java developer on a code cleaning plug-in for Eclipse IDE.
