Tried to explain the basics of how topology is transforming certain aspects of data analysis. Started by talking about the successful  <a href="https://www.ayasdi.com/">Ayasdi company</a> which uses topological methods to investigate financial and other data. Then talked about phylogenetic trees and the related notion of "barcodes".  This <a href="https://www.pnas.org/content/pnas/110/46/18566.full.pdf">paper by Gunnar Carlsson and others</a> uses topological data analysis to study the evolution of viruses in pandemics.
