Deep Learning, ML on Systems, Query Optimization

I hold a Master’s degree in Data Science from the National and Kapodistrian University of Athens, following a Bachelor’s degree in Informatics and Telecommunications. I am currently working as a research assistant at the Athena Research and Innovation Center, under the supervision of Dr. Georgia Koutrika.
My research focuses on the intersection of machine learning and database systems, particularly in leveraging deep learning techniques to enhance query optimization.
