I am very active contributing to open-source software on GitHub (username jasongrout), an online repository for software. My recent development work has centered on Project Jupyter and IPython subprojects, including JupyterLab and Jupyter Widgets, as well as many other areas of Project Jupyter.
Please see my GitHub profile at https://github.com/jasongrout for more details.
Some projects I’ve worked on significantly in the past include:
- SageMath (GitHub), a math software distribution built in Python that interfaces with many state-of-the-art math programs and libraries. I worked extensively on SageMath during 2007–2014 and helped maintain the large public SageMath Notebook service.
- SageMath Notebook, an online interface to SageMath preceding the Jupyter notebook.
- SageMath Cell Server, another online interface to SageMath allowing anyone to easily embed live SageMath computations into any webpage. I started the project with six undergraduate Drake University students and led the development for several years. I transitioned leadership of the project to Andrey Novoseltsev in 2014 when I left academia and joined Bloomberg. The cell server is used in a number of online resources, including textbooks, notes, online homework systems, and more.
- PyThreeJS, a wrapper around three.js to provide interactive 3d graphics for the online JupyterLab and Jupyter Notebook. I started the project with three Drake University students and led the development for several years.
- Minimum Rank Library, a library for calculating the minimum rank, zero forcing numbers, and other related parameters on graphs. I was the lead developer and also mentored several graduate students from Iowa State University who developed part of the library.
- UTMOST: Undergraduate Teaching in Mathematics with Open Software and Textbooks (with Rob Beezer, Marja-Liisa Hassi, Tom Judson, Kiran Kedlaya, and William Stein), $525,000, National Science Foundation, 2010-2014. NSF Department of Undergraduate Education CCLI type 2 grant for integrating and promoting Sage and open textbooks in undergraduate mathematics curriculum. My responsibilities include implementing improvements to Sage, directing work by students, training faculty and supervising test sites, helping organize workshops, and contributing curricular materials. Original proposal, Supplement
- Sage: Using Open-Source Mathematics Software with Undergraduates (with Rob Beezer and Karl-Dieter Crisman), $10,400, Mathematical Association of America Professional Enhancement Program, 2010. We introduced several dozen faculty members to using Sage in the classroom and helped them prepare curricular materials through an online workshop spanning several days throughout the summer and follow-up during the semester. Proposal, Supplement, Report, Materials
- Sage: Using Open-Source Mathematics Software with Undergraduates (with Karl-Dieter Crisman), $8,500, Mathematical Association of America Professional Enhancement Program, 2011. We introduced several dozen faculty members to using Sage in the classroom and helped them prepare curricular materials through an online workshop spanning several days in the summer and follow-up during the semester. Proposal, Report, Materials
- Scalable Internet Interface for Sage, $2,340, Drake University, 2011. This grant funded two Drake students to help create the SageMath Cell Server, a scalable public Internet interface to the Sage, allowing Sage to embed in any webpage. Proposal
I was one of the recipients (with other members of the Jupyter Steering Council) of the Association for Computing Machinery 2017 Software System Award for Project Jupyter.
Ben Woodruff and I worked on a semester-long set of problems to explore multivariable calculus, and both of us have used versions of these notes for many years. Highlights include presenting the multivariable derivative as a matrix of partial derivatives and presenting comprehensive physical applications for line, double, surface, and triple integrals using differentials and the concept of weighted averages.
These problems are based on our lecture-style set of notes (source, alternate PDF from GitHub). Ben wrote the initial versions of both the lecture-style notes and the problem set, then I joined as a coauthor with extensive modifications.
I developed a set of problems to guide an undergraduate student through a semester course using Trefethen and Bau’s Numerical Linear Algebra textbook (ISBN 0898713617). We used these notes in a problem-oriented IBL-style course. The source is on GitHub.
This linear algebra textbook was written by Ben Woodruff (Brigham Young University-Idaho) and I made many edits to it. This book uses an innovative approach to introduce important concepts early in the course and build on those throughout the course.
