Dmitriy Morozov

About

I am a research scientist in the Data Analysis and Visualization group at the Lawrence Berkeley National Lab. My main interests are computational topology and geometry, especially, as they apply to data analysis. I did my graduate studies at Duke, where my advisor was Herbert Edelsbrunner, followed by a postdoc at Stanford working with Leo Guibas and Gunnar Carlsson.
