About Me

I am a data scientist at Pareto AI (full-time) and a researcher in neuroscience at the Mind & Brain Lab at the Department of Psychology, University of Ljubljana (part-time). Currently, I am working towards a Ph.D. in Statistics. My Ph.D. research focuses on developing a statistical framework for multimodal (EEG-fMRI) neuroimaging data integration for investigating the role of cortico-subcortical interactions in whole-brain dynamics.

I am passionate about exploring the mechanisms within the natural world and uncovering the hidden elegance of complexity. I find satisfaction in vigilantly traversing every stage of exploration, from data collection to signal processing, data analyses, and systems design.

Beyond my professional endeavors, I thrive on applying my problem-solving skills to conquer challenges. Whether it's tackling mountainous terrain or flying through the skies in an aircraft, I embrace the thrill of adventure as an extension of my curiosity and desire for pushing boundaries.
