I investigate the geometric science of information with applications ranging from machine learning to data science, visual computing, and artificial intelligence.
I deal with large high-dimensional, noisy, and heterogeneous dynamic datasets that are inherently non-Euclidean in nature.
To build advanced models and learning machines that capture both regularities and variations of datasets,
I develop geometric computational methods and toolboxes.
Since 2013, I co-organize the biannual international conference "Geometric Science of Information" (GSI).
