I am a postdoctoral researcher in the TurkuNLP Group at the University of Turku, Finland.

My main research interest is a Multilingual Natural Language Processing. Currently, I’m working on multilingual data mixes in OpenEuroLLM and HPLT projects.

Since October 2023 until March 2025 I worked as a postdoctoral researcher in Aalto University in the Trust-M project under the supervision of Prof. Nitin Sawhney from CRAI-CIS and Prof. Tom Bäckstöm from Speech Interaction Tehcnologies research groups.

I received my doctoral degree in ICT at Web Science and Social Computing research group of Universitat Pompeu Fabra, Barcelona where I was advised by Prof. Carlos Castillo. My doctoral thesis focuses on developing a multilingual approach to extract, summarize, and prioritize crisis-related information from social media, enabling emergency managers and responders to efficiently monitor events, validate data, and address critical help-seeking requests.

I received my Master’s Degree (with honors) in Computational linguistics from the National Research University Higher School of Economics under the supervision of Prof. Nikolay Karpov with a dissertation titled “Deep Semantics in Expert Finding Systems.” We proposed an LSI-based topic similarity search model for authors of academic publications.

Before starting my Ph.D., I worked in Havas, Ailove and Convergent.
