Learning to decideunder uncertainty.

I study the mathematical foundations of online learning and decision-making—especially when the environment is uncertain, adaptive, or adversarial.

I am a Ph.D. student in Electrical and Computer Engineering at the Georgia Institute of Technology, advised by Prof. Matthew Hale and co-advised by Prof. Dmitrii Ostrovskii. My work connects online optimization, optimal experimental design, and multi-agent systems.

Research focus

Principled learning for interactive systems.

I build algorithms and theory for decisions that unfold over time, where information is limited and other agents may respond.

01

Online learning

Algorithms with finite-time guarantees for sequential decisions in uncertain and strategically changing environments.

02

Experimental design

Adaptive methods for choosing informative experiments while balancing geometry, computation, and regret.

03

Multi-agent systems

Learning in games where agents adapt, objectives evolve, and interaction itself shapes the data we observe.

Selected work

Publications & current research.

My recent work develops learning methods for interactive, sequential environments, building bridges between regret theory, experiment design, and strategic decision-making.
