We’d like to congratulate Christina Giannoula on receiving the Best Doctoral Thesis Award from her home university National Technical University of Athens (NTUA) for her PhD thesis on “Accelerating Irregular Applications via Efficient Synchronization and Data Access Techniques“.

The Iakovos Gyourunlian PhD award recognizes the best doctoral thesis with a subject of industrial interest in the School of Electrical of Engineering & Computer Engineering at NTUA and was given through the Michael N. Stasinopoulos Charitable Foundation.

Christina completed her PhD in Sept 2022 and was co-advised by Onur Mutlu. She is now a postdoctoral researcher at the University of Toronto in the EcoSystem research group of Gennady Pekhimenko and continues to have strong collaborations with our group working on hardware/software co-design of emerging applications, designing scalable memory hierarchies and efficient hardware support for synchronization and concurrency.

Congratulations, Christina, on this well-deserved award!
