Alex Gittens


Before joining Rensselaer as an Assistant Professor of Computer Science in 2017, Dr. Gittens was a research scientist at eBay Research Labs and a postdoctoral scholar at the International Institute of Computer Science and the Department of Statistics, UC Berkeley. His interests lie in applying randomness to computational linear algebra, machine learning, and statistics, and are motivated by the goal of efficiently extracting information from massive data sets while maintaining guarantees on rigor and accuracy.


Other Focus Areas

Kernel Methods, Randomized Numerical Linear Algebra, Large-scale Machine Learning, Low-rank approximation and Sketching
