705G, 45 Rue des Saints-Pères, 75006 Paris, France

I am a PhD student at Université Paris Cité, advised by Professor Themis Palpanas.

I am broadly interested in vector data management, with specific focus on exact and approximate nearest neighbor vector search

I have obtained my MSc in computer science from EPFL in Switzerland, and my BSc in computer science from the University of Crete in Greece, where I graduated first in my class.

I have held student researcher positions at Google in the United States, the Commision of Atomic Energy (CEA) in France, DIAS EPFL lab in Switzerland (summer@epfl), and FORTH-ICS in Greece.

I am honored to have received several awards and scholarships, including a PhD scholarship from the Onassis Foundation, MSc scholarships from the Latsis Foundation and the Onassis Foundation and undergraduate scholarships from the University of Crete. I was also honored to participate as a young computer scientist in the 9th Heidelberg Laureate Forum.
