machine learning; networks; data science; time series; financial applications

I am interested in the development and mathematical & statistical analysis of algorithms for data science, network analysis, and certain computationally-hard inverse problems on large graphs, with applications to various problems in machine learning, statistics, finance, and engineering, often with an eye towards extracting structure from time-dependent data which can be subsequently leveraged for prediction purposes. More specifically, I have considered problems that span

- spectral and semidefinite programming (SDP) relaxation algorithms and applications, group synchronization, ranking, clustering, phase unwrapping
- network analysis: community and core-periphery structure, network time series, anomaly detection
- nonlinear dimensionality reduction and diffusion maps, intrinsic slow variables in dynamic data
- statistical analysis of big financial data, statistical arbitrage, market microstructure, limit order books, risk models
- low-rank matrix completion, distance geometry problems, rigidity theory, sensor network localization and 3D structuring of molecules

I finished my Ph.D. in Applied and Computational Mathematics (PACM) at Princeton University in 2012. I joined the Department of Statistics in 2018, and have also been an affiliated faculty at the Mathematical Institute. During 2017-2018 I was a Turing Research Fellow within the Department of Statistics + Mathematical Institute at University of Oxford and The Alan Turing Institutein London. Throughout 2013-2016 I was a CAM Assistant Adjunct Professor in the Department of Mathematics at UCLA. I spent Fall 2014 as a Research Fellow at the Simons Institute for Theory of Computing at UC Berkeley, in the program Algorithmic Spectral Graph Theory, and Spring 2014 as a Research Fellow at ICERM, at Brown University, in the Network Science and Graph Algorithms program. During 2012-2013 I was Associate Quantitative Researcher (Quant) in the Statistical Arbitrage - Quantitative Trading Group, at Bank of America Merrill Lynch, New York.
