Email: lastname (at) ece (dot) ucr (dot) edu

PhD in Electrical Engineering, California Institute of Technology, 2015

SODA Lab advances statistics and optimization for data science and AI.

UPDATE: Our group will be moving to the ECE Department at the University of Michigan in Fall 2023!

Research focus: Statistical learning meets (non)convex optimization to enable resource efficient AI/ML

Current topics: deep learning theory, resource efficiency, learning & control, transformers and attention

PhD recruiting: I will be recruiting at least 2 students for Fall 2023 at the University of Michigan.
Our lab's focus is principled and empirically-impactful ML methods (see criteria below). Please drop an email!

Self-motivated and intellectually curious with how things (e.g. AI/ML systems) work
Strong background in applied math (stats, optimization) and machine learning methods
Research experience in ML theory OR innovative AI/ML algorithms (optimization, architectures, NLP, RL …)
