About me
I am a postdoctoral researcher in natural language processing (NLP) in the Department of Computer Science at the University of British Columbia (UBC), where I work with Dr. Vered Shwartz. My research develops language technologies for reasoning in social, conversational, and evidence-rich settings, with an emphasis on information seeking, stance understanding, and dialogue systems.
I completed my PhD at the Faculty of Computer Science, Dalhousie University, under the supervision of Dr. Evangelos Milios. I previously earned a BSc in Applied Mathematics from Odesa I. I. Mechnykov National University in Odesa, Ukraine.
Research
My research asks how language technologies can make reliable decisions when the available information is incomplete, ambiguous, or socially situated. I study this question through three connected directions:
- Information-seeking agents: combining retrieval, uncertainty estimation, and follow-up questioning to gather the evidence needed for reliable answers.
- Social and argumentative reasoning: understanding stance, beliefs, and context in dialogue.
- Trustworthy applied NLP systems: supporting users in high-stakes domains through source-grounded dialogue, interpretable reasoning, and reliable explanations.
