I have been extremely impressed with both the NDSSL group and Ilya's group, as model examples of two large transdisciplinary research groups made up of people with diverse backgrounds (e.g., math, biology, cs, stats, engineering, physics, econ, etc.) who come together and tackle a mainstream science problem in a creative way. Both groups have exceptional records of publications, grant funding, and great science. They exemplify the definition of "transdisciplinary."
I have taught 16 different classes at Clemson, ranging from 1000-level Calculus to 9000-level graduate classes, and including diverse subjects such as algebra, analysis, geometry, topology, mathematical modeling, PDEs, and probability. My educational YouTube Channel has (as of June 2018) approximately 4000 subscribers and 400k views. Of particular interest is a 51-video playlist of my online Differential Equations (Math 2080) class, a 38-video playlist of its follow-up course, my online Advanced Engineering Mathematics (Math 4340) class, which is basically an applied analysis course on PDEs and Fourier series. I also have a 46-video playlist of my online Abstract Algebra (Math 4120) class, which is quite unique in that it takes a very visual and intuitive approach using Cayley diagrams.
