How does one integrate local information into a global understanding?
How does one extract intrinsic structure underlying a data set? 
How does one capture features of data that are invariant to a wide range of transformations? 
These are some of the fundamental questions motivating the field of topological data analysis (TDA).  In this talk, I will give a gentle introduction to TDA. I will start with some of its high profile successes in cosmology and cancer research. Then, I will discuss some of my own work on algorithms for TDA addressing problems such as multi-scale data signatures, sensor network coverage testing, and computing meaningful distances between curves and surfaces.
