Large and complex data arise in many application domains, such as nuclear engineering, combustion simulation, weather prediction and brain imaging.
However, their explosive growth in size and complexity is more than enough to exhaust our ability to apprehend them directly.
Topological techniques which capture the "shape of data" have the potential to extract salient features and to provide robust descriptions of large and complex data.
My research develops pertinent theoretical and algorithmic advancements in topological data analysis, and establishes their applications in simplifying and accelerating the visualization and analysis of large, complex data sets.
In particular, in this talk I will describe a novel visualization framework for the simplification and visualization of vector fields, based on the topological notion of robustness that quantifies their structural stability.
I will also discuss several other representative areas in my research that focus on developing novel, scalable and mathematically rigorous ways to rethink about complex forms of data, from high-dimensional point clouds, to large-scale networks and multivariate ensembles.
