### Robert Ghrist

Title: Homological Tools for Data

Abstract: The past fifteen years has witnessed a dramatic burst of applications of topological thinking and theorems in the applied sciences, ranging from statistics to sensor networks, neuroscience, and more, to be surveyed here. This talk, meant for newcomers to the field, will introduce homology and persistent homology, and demonstrate why these are exciting and practical new tools in applied mathematics.

Biography: Robert Ghrist (Ph.D., Cornell, Applied Mathematics, 1995) is the Andrea Mitchell PIK Professor of Mathematics and Electrical & Systems Engineering at the University of Pennsylvania. He is a recognized leader in the field of Applied Algebraic Topology, with publications detailing topological methods for sensor networks, robotics, signal processing, tracking, neuroscience, and more. He is the author of a leading textbook on the subject (Elementary Applied Topology, 2014) and is the winner of the Chauvenet Prize, the highest award given for mathematical expository writing.

His prior work in leading the DARPA DSO SToMP project and participating in several DoD MURIs is complemented by NSF CAREER, NSF PECASE, SciAm50, and Vannevar Bush Faculty Fellow awards.

Ghrist is also a dedicated expositor and communicator of Mathematics, with teaching awards that include the MAA James Crawford Prize, Penn's Lindback Award, and the S. Reid Warren award in Engineering at Penn. Ghrist is the author and animator of popular videos for calculus, featured in the New York Times, BoingBoing, and Gizmodo.

### Sayan Mukherjee

Title:

Abstract:

Biography: Sayan Mukherjee is a Professor of Statistical Science, Mathematics, Computer Science, and Biostatistics & Bioinformatics at Duke University. Sayan received his PhD from MIT and was a postdoc at the Broad Institute. He is a Fellow of the Institute of Mathematical Statistics.His research covers Bayesian methodology; computational and statistical methods in statistical genetics, quantitative genetics, cancer biology, and morphology; discrete Hodge theory, geometry and topology in statistical inference; inference in dynamical systems; machine learning; and stochastic topology

### Michael Robinson

Biography: Prof. Robinson is an associate professor in American University's Department of Mathematics and statistcs. He is an expert on topological signal processing and has led numerous research projects on the applications of topology to signal processing and remote sensing. He earned a Bachelor's degree in Electrical Engineering (2002) and a Master's degree in Mathematics (2003) from Rensselaer Polytechnic Institute. From that time, he has worked on projects involving radio propagation and network planning, bistatic radar processing, and advanced radar simulation. In 2008, he earned a Ph.D. in Applied Mathematics at Cornell University in which he developed topological methods for studying the dynamics of parabolic equations.

Prof. Robinson's work is characterized by an aggressive application of sophisticated mathematical techniques to detailed, practical models of systems. He is the lead developer of the open-source PySheaf topological analytic toolkit. Additionally, Prof. Robinson has found many new examples of practical, theoretically-motivated algorithms, and has demonstrated them on laboratory systems of his own design. Prof. Robinson maintains active relationships to industry, through which he regularly transitions concepts into prototype systems.
