About Me

I am a researcher with a focus on Information Retrieval, Natural Language Processing, and Large Language Models. I recently completed my Ph.D. at the IRLab of the University of Amsterdam, where I was advised by Evangelos Kanoulas and Andrew Yates.

During my Ph.D., I interned at Microsoft Research in Nairobi and the Amazon search team in Barcelona. Before that, I worked as a Data Scientist at bol.com. I hold a Master’s degree in Data Science from the University of Amsterdam, and a Diploma in Electrical and Computer Engineering from A.U.Th.
