Ewa Beldzik, PhD

A research assistant, PostDoc graduate, at the Neuroergonomics Department at the Institute of Applied Psychology, Jagiellonian University, Krakow, Poland.

She has gain an experience with fMRI techniques during the internship at the Medical College of Wisconsin, Milwaukee, USA. She took a 6-month internship at the University of Amsterdam, Netherlands, within the Erasmus programme under the supervision of dr Sander Daselaar. She is experienced with preparation, conducting the experiment, and data analysis procedures of fMRI technique. She also participated in EEGLab workshop in Jyvaskyla, Finland and is currently working with dense EEG within the grant conducted by Prof. Tadeusz Marek.

Her research interests focus on numerical cognition, visuospatial neural processes as well as separating task-related neural networks. Her PhD thesis, under supervision of Prof. Wojciech Froncisz, will concern applying Independent Component Analysis to fMRI and EEG data in order to separate distinct cognitive processes of the human brain.
