Biography: Namrata Vaswani is Anderlik Professor of Electrical and Computer Engineering, and (by courtesy) of Mathematics, at Iowa State University. She received a Ph.D. in 2004 from the University of Maryland, College Park and a B.Tech. from Indian Institute of Technology (IIT-Delhi) in India in 1999. Her research interests lie at the intersection of statistical machine learning / data science, computer vision, and signal processing.

She is a recipient of the Harpole-Pentair Assistant Professorship (2008-09); the Iowa State Early Career Engineering Faculty Research Award at Iowa State (2014); the IEEE Signal Processing Society (SPS) Best Paper Award (2014) for her T-SP paper on Modified-CS co-authored with her graduate student Lu; the University of Maryland ECE Distinguished Alumni Award (2019), the Iowa State Mid-Career Achievement in Research Award (2014), and the Anderlik Professorship (July 2019-present). Vaswani is an IEEE Fellow (class of 2019) for contributions to dynamic high-dimensional structured data recovery.

Professional Service and Talks/Tutorials: Prof. Vaswani taught an invited short-course on PCA and Robust PCA for Modern Datasets at IIIT-Delhi under the Global Initiative of Academic Networks (GIAN) program of Government of India in December 2017. She recently also gave an invited talk at the International Conference on Computer Vision (ICCV) workshop on Robust Subspace Learning. She has given invited seminars at universities around the world including a department colloquium at UIUC and a department seminar at CMU. Vaswani has served the SPS and IEEE in various capacities. She is an Area Editor for IEEE Signal Processing Magazine and has served twice as an Associate Editor for IEEE Transactions on Signal Processing. She is the Lead Guest Editor for a Proceedings IEEE Special Issue on Rethinking PCA for Modern Datasets, and of a Signal Processing Magazine Feature Cluster on Exploiting Structure in High-dimensional Data Recovery, both of which will appear in 2018. She is also the Chair of the Women in Signal Processing (WiSP) Committee, a steering committee member of SPS's Data Science Initiative, and an elected member of the SPTM and IVMSP Technical Committees.


Research: Vaswani's recent research has focused on provably correct and practically useful online (recursive) algorithms for various structured (big) data recovery problems. She has worked on (a) dynamic compressive sensing (CS), (b) dynamic robust principal component analysis (RPCA), and most recently on (c) Phaseless PCA and Subspace Tracking (structured phase retrieval). Online algorithms are needed for real-time applications, and even for offline applications, they are typically faster and need less storage compared to batch techniques. Most importantly, her work on these problems has shown that online solutions provide a natural way to exploit temporal dependencies in a dataset, without increasing algorithm complexity; and that exploiting such dynamics provably results in either reduced sample complexity (in case of dynamic CS) or improved outlier tolerance (in case of dynamic RPCA). The former implies proportionally reduced acquisition time for applications such as MRI where data is acquired one sample at a time. The latter implies increased robustness to outliers such as large-sized or slow changing foreground occlusions in videos. All theoretical claims are backed up by extensive experimental evaluations for various video analytics applications and medical imaging applications. In the past she has also worked on particle filtering (sequential Monte Carlo) algorithms, and in computer vision.
