Short Bio [In third person]

Aadirupa Saha has been an Assistant Professor in the Department of Computer Science at the University of Illinois Chicago (UIC) since Fall 2025. She is a member of the UIC CS Theory group, as well as IDEAL Institute. Prior to this, she was a Research Scientist at Apple MLR, working on Machine Learning theory. She completed her postdoctoral research at Microsoft Research (NYC) and earned her PhD from the Indian Institute of Science (IISc), Bangalore.

Saha's primary research focuses on AI alignment through Reinforcement Learning with Human Feedback (RLHF), with applications in language models, assistive robotics, autonomous systems, and personalized AI. At a high level, her work aims to develop robust and scalable AI models for designing prediction systems under uncertain and partial feedback.

[Optional] Specifically, Saha is deeply motivated by the tremendous potential of AI to democratize learning—reshaping our current education system into a truly adaptive, accessible, and personalized experience for every learner! Driven by this transformative power of generative AI and language models, she envisions building the foundations for equitable, intelligent education systems that turn this vision into reality. Her research focuses on developing futuristic educational models by leveraging her expertise in AI alignment with human feedback, alongside tools from Machine Learning (Online Learning, Bandits, and RL theory), Optimization, Federated Learning, Differential Privacy, and Mechanism Design.

[Optional] Saha has been a part of several organizational efforts and tutorials over the last few years. Notably, she serves as the communication chair for RLC, 2026. Besides her community services inlcude a keynote talk at DA2PL Conference, [NeurIPS, 2023] tutorial on Preference Learning, [UAI, 2023] tutorial on Federated Optimization, two tutorials at [ECML, 2022] , [ACML, 2021], three ICML workshops [ICML, 2024] , [ICML, 2023] , [ICML, 2022], an IDEAL special progrem workshop, and two TTIC workshops [TTIC, 2023], [TTIC, 2022]. In addition, Saha has also served in several panel discussions and senior reviewing committees for major ML conferences.
