About

At the Graphics-Visualization-Computing-Lab at IIIT-Bangalore, we work on topics of visual analytics and spatial computing. Our interests lie in developing interdisciplinary data models and techniques for visualization and spatial processing involving second-order tensors, matrices, and complex networks for spatio-temporal and multivariate data. We work with datasets such as point clouds (unstructured data), volumetric grids/tabular data (structured data), and networks.
We work on applications in geosciences/earth observations, biological and brain networks from biomedical data, public health data from large-scale population/household surveys, chart image analysis, and others. We actively work with domain experts, such as oceanographers, GIS practitioners, survey data analysts, biologists, and medical doctors, in devising novel solutions.
GVCL is one of the founding and participating labs of the Center for Data Sciences (CDS) at IIITB. GVCL is closely affiliated with the E-Health Research Center (EHRC) at IIITB. GVCL is a participating lab in the SIG at IIITB for "Spatio-temporal Modeling, Simulation, Analytics, and Visualization (STeMSAV)"
