Apoorv Vikram Singh
Ph.D. Candidate
Computer Science
NYU Tandon


I am a second year Ph.D. student at the department of Computer Science at the NYU Tandon School of Engineering. I am a part of the Algorithms and Foundations Group, where I am being advised by Dr Chris Musco.

Before joining NYU, I was a visiting researcher at the MODAL team in INRIA Lille where I worked with Dr Hemant Tyagi and Dr Mihai Cucuringu (Univ of Oxford). Before that I was a Project Associate in the Dept. of Computer Science and Automation, Indian Institute of Science, where I worked with Dr Anand Louis and Dr Amit Deshpande (Microsoft Research, India). I obtained my undergraduate degree from IIIT Bangalore.

Research Interests: My research interests lie at the intersection of theoretical computer science and statistical machine learning. Currently, I am working on problems in the area of spectrum estimation of matrices in sub-linear time. I am also reading about Sum of Squares Hierarchy, and Discrepancy Theory (see Reading Group).
