I Am finishing my PhD in Mathematics at Saint Louis University (SLU) in St. Louis, Missouri, United States of America. I have completed all my requirements including passing my qualifying exams in Topology, Algebra, and Differential Geometry. I Am researching Discrete Geometry and Differential Geometry and writing my PhD Dissertation on Tanglegrams and Crossing Numbers.
Differential Geometry studies the changes in the shapes around us. The National Geospatial-Intelligence Agency (NGA) for the United States has offices here in St. Louis. They study changes in the terrain of the Earth. I love that. Snapchat filters also analyze the shape of our faces and attach a predesigned filter to our face using Differential Geometry. To access a filter on Snapchat, press your finger on the screen of your phone where your face is and hold it there. The options will appear on the bottom. All these photos were taken with Snapchat. I love Snapchat.
