Oleksandra LEVCHENKO

Teacher-Researcher, PhD

Alexandra Levchenko is currently an Associate Professor at Isep. Before joining Isep, she was a Research Associate at Paris Cité University (2021–2023), where she collaborated with psychologists to apply machine learning algorithms to interdisciplinary projects.

At Inria (2015–2021), she worked on distributed algorithms for large-scale data processing, deep learning in computer vision, and polystores for querying and integrating data from heterogeneous data stores.

She obtained her PhD in Computer Science from the Ukrainian Ministry of Education and Science in 2013 and worked as an Associate Professor of Computer Science at Odessa National Polytechnic University in Ukraine.
