I am a Research Assistant and PhD student(thesis submitted) at the Institute of Computer Science at the Warsaw University of Technology. I am working under the supervision of Prof. T. Gambin and P. Andruszkiewicz on Multilinguality and Modular Deep Learning.

Recently, I was a Research Associate (PostDoc) at The University of Edinburgh in the StatMT group under the supervision of A. Birch (with whom I also worked during my research visits at UoE in 2021 and 2023). I have also done internships at Booking.com (in the NMT Team), Google Zurich and Amazon Luxembourg.
