  Discrete Morse Theory, Vector Fields and Material Science*Published paper available at arXiv:1801.09530*Introduction: One of the important tasks of materials science is to compare structural properties of substances, such as comparing relative conductivities or porousness of two metals. Such comparison traditionally requires a lot of experimental data, time and financial resources. Discrete Morse Theory provides a toolkit for studying key qualitative properties of shapes and helps to save time and money.▪ Publication: RGB image-based data analysis via discrete Morse theory and persistent homology, (first author) with C. Szul, A. Manawa, N. Rasekh, R. Guzman, R. Davidson, arXiv:1801.09530▪ Designed converters using Python to convert RGB images into grayscale, used Australian National University’s source code to create discrete Morse functions (DMF) to extract key topological information from images, and constructed custom models of DMF vector fields in a cubical complex▪ Generated data-informative persistence diagrams to describe the birth and death time of persistence pairs, enabling users to predict future image-based data behavior with the life-span information of topological features in the input images▪ Applied the theory to perform analysis on open-source heat maps of water scarcity variability and crime rates variability dataPresentations:▪Presented the research project at UIC Undergraduate Mathematics Symposium 2016.▪Panelist at IGL Information Session 2016.▪Presented the research project at IGL Open House Spring 2016, Fall 2016.
