Paul L Bendich, Associate Research Professor of Mathematics and Assistant Director of Curricular Engagement
I work in computational topology, which for me means adapting and using tools from algebraic topology in order to study noisy and highdimensional datasets arising from a variety of scientific applications.
My thesis research involved the analysis of datasets for which the number of degrees of freedom varies across the parameter space. The main tools are local homology and intersection homology, suitably redefined in this fuzzy multiscale context.
I am also working on building connections between computational topology and various statistical data analysis algorithms, such as clustering or manifold learning, as well as building connections between computational topology and diffusion geometry.  Contact Info:
