Oleg Balabanov

I am a research scientist in Department of Statistics at UC Berkeley and Big Data group at ICSI, as well as an affiliate researcher in Machine Learning and Analytics group at Lawrence Berkeley National Laboratory.

Most of my work focuses on randomized linear algebra and numerical methods for large-scale modeling, optimization, and machine learning. My supervisor is Michael Mahoney.

Previously, I did a postdoc in Paris at Inria and Jacques-Louis Lions Laboratory at Sorbonne, under the supervision of Laura Grigori. I earned a joint PhD degree in applied mathematics and civil engineering as part of the Simulation in Engineering and Entrepreneurship Development program, a collaboration between Centrale Nantes and Polytechnic University of Catalonia (UPC), where I was supervised by Anthony Nouy and Nuria Parés. Prior to that, I earned a joint master's degree in Computational Mechanics from Swansea University and UPC. My undergraduate studies were in Taiwan at National Chiao Tung University (now National Yang Ming Chiao Tung University), where I double-majored in electrophysics and applied mathematics.
