Dr. Olivera Kotevska is a leader in trustworthy scientific AI in the Computer Science and Mathematics Division (CSMD) at Oak Ridge National Laboratory (ORNL), where she directs ORNL’s role in a multi-institutional DOE program on privacy-preserving federated learning for scientific foundation models and shapes AI safety and security for the DOE Genesis Mission. Her research defines the emerging field of trustworthy AI for multi-institutional science, spanning differential privacy, federated learning, gradient privacy, and autonomous scientific computing. She is the 2025 R&D 100 Award winner for PRESTO (Privacy REcommendation and SecuriTy Optimization), a privacy mechanism recommendation system for federated learning at scale, and the recipient of the 2022 Highly Cited Research Paper Award from Applied Energy. Her CVPR 2026 paper on class-level unlearning in vision models was selected as a Highlight.

Prior to joining ORNL in 2019, Dr. Kotevska was an international guest researcher at the National Institute of Standards and Technology (NIST), Maryland, USA, where she was part of the NIST Smart Cities Framework Team and contributed to some of the earliest foundational work in that domain. Before her PhD, she built and shipped production software actively used by millions of consumers — at Nuance Communications (UK, voice and AI systems), Vivo (Brazil, mobile telecommunications), T-Mobile (Macedonia, mobile services), and Renault (France, automotive software). She received her Ph.D. in Computer Science from the Université Grenoble Alpes, France, and B.S. and M.S. degrees in Computer Science and Engineering from the University of Ss. Cyril and Methodius, Skopje, Macedonia.

With over $33M in competitive funding secured across DOE, NNSA, VA, and DoD programs, Dr. Kotevska brings a portfolio perspective to research investment — from early-stage laboratory concepts through open-source deployment and federal policy. She is a Senior Member of IEEE, an Advisor to the IEEE USA Artificial Intelligence Policy Committee and the IEEE Computational Intelligence Society Government Activities Committee, and has responded directly to White House OSTP and NIST solicitations on privacy-enhancing technologies and AI security. She has mentored 15 PhD students across 10 universities in the United States and Europe, and 30 students and interns in total.

Research Focus

Core research areas spanning theory and systems:

  • Federated learning — communication-efficient and privacy-preserving training across decentralized scientific data
  • Differential privacy — formal guarantees for data release and model training in sensitive domains
  • Trustworthy AI for Science — robustness, explainability, safety, and security of models under adversarial conditions
