The visualization challenge will directly increase the capacity for data science education and workforce development. The online visualization mini-course will be followed by a visualization challenge with three categories (video, static image and 3D printed porous microstructure), and each prize will have three prizes judged by five faculty and researchers selected from the Southern Universities that have posted on or have been involved in Digital Rock Portal data curation. Students and young researchers from the US universities will get exposed to advanced scientific data visualization, curation and numerical simulation concepts by participating in the course and/or challenge. All products (mini-course videos, Jupyter Notebooks, scripts and derivative data) will be posted on YouTube, GitHub or Digital Rocks Portal as applicable, and thus create a permanent source of education materials.
