My research interests lie in the analysis and visualization of data. We live in the era of big data revolution; the large amounts of data generated around the globe every day contain abundant information that we must extract and understand. Understanding data through visual and/or analytical means can impact human growth in a variety of disciplines, ranging from but not limited to understanding the universe to tracing our origin, from bettering the socio-economic progress to understanding the spread and causes of a disease, from taking us to Mars to optimizing business practices. The importance of data analysis and visualization is conveyed by the quote: "Without understanding data, you're just another person with an opinion!"
I am interested in playing with data of a wide variety, and contribute to enhance the fields of scientific and information visualization. A gamut of other research areas fascinate me. Given some spare time from my current work and responsibilities, I would like to be involved in Mathematical Modeling & Simulation, Probability Theory & Stochastic Processes, Markov Models & Queueing Theory, Computational Geometry, & Algorithms.
My current focus at LLNL is the topological analysis of the behavior of Lithium ions in different electrolytes, simulated at LLNL using first-principles molecular dynamics. This project is a partnership between SDAV and the BES program of SciDAC. As a part of my Ph.D. research, I developed tools for consistent feature extraction from vector field data, which can be used for a broad spectrum of applications ranging from combustion to weather, aerodynamics to cosmology, etc. I have worked extensively on theoretical and computational frameworks for robust analysis of vector fields.
