Thesis "NLP Models for Automatic Extraction of Political Statements at the Passage Level", in which I used AI explainability methods to study how LLMs understand linguistic structures (features) to make predictions. Along the process, I built a web crawler, web annotation tools, NLP models and datasets, and a seminar in NLP and Information Extraction that I lectured for four years at BTU.

Thesis: “Effect of emotion on Marketing Landing Page Conversion”, in which I ran experiments to measure the effect of emotion on landing page conversion, using physiological instruments to measure emotional arousal (eye tracking, Empatica E4 wristband EDA sensor) and a self-reported tool to measure emotional valence. This research establishes a multidisciplinary method in interaction design to measure user experience in the context of UI design and marketing.
