About Me!
I am a Machine Learning Scientist and Ph.D. Candidate at the University of Amsterdam (graduating April 2027), specializing in Natural Language Processing (NLP) and Information Retrieval (IR). My research covers key aspects of agentic conversational search systems, including retrieval, LLM-based evaluation, personalization, synthetic data generation, and user simulation. I have published over 10 papers in these areas, alongside a proven track record of building production-scale NLP pipelines for Booking.com and the European Patent Office (EPO) at Leiden University. Additionally, as a co-organizer of the TREC iKAT track, I have helped publish reusable benchmarks, evaluation methodologies, and tools for information-seeking systems.
My curriculum vitae is available here.
