About Me

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 research and development of Machine Learning infrastructure to support the multi-laborarory effort to understand cancerous cell growth induced by RAS protien. We are developing the first of its kind multiscale simulation of RAS biology on cell membranes to understand intricate interactions between the two at long spatial and temporal scales.

I am also developing a new in-memory representation to support adaptive representation of data, in terms of both resolution and precision, allowing many standard visualizaiton and analysis algorithms. I am also involved in the topological analysis of molecular dynamics data, where I have developed a robust topological analysis tool, TopoMS. 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.
