Javid Ebrahimi
Staff Research Scientist
Risk Modeling
Research areas: Deep Learning, Natural Language Processing, and Graph Neural Networks

Dr. Javid Ebrahimi joined Visa Research as a Staff Research Scientist in January 2019. Javid received his Ph.D. in Computer Science from University of Oregon in 2018. His Ph.D. work focused on adversarial examples and robustness of neural networks. Prior to joining Visa, Javid was a Graduate Research Assistant at University of Oregon. As a member of the Risk Modeling team, his research interests are in deep learning, natural language processing and graph neural networks. He has published several papers in international conferences and journals, including Annual Conference of the Association for Computational Linguistics (ACL), Empirical Methods in Natural Language Processing (EMNLP), North American Chapter of the Association for Computational Linguistics (NAACL), and others.
