Mert Coşkuner

MSc student in Computer Science & Engineering at Sabancı University and researcher at TÜBİTAK BİLGEM. I work on trustworthy and efficient machine learning: Byzantine-robust and private federated learning, backdoors in graph neural networks, adversarial robustness and distillation, and low-bit quantization of multilingual language models.
