This is an edited version of a review of my scholarship, as of Spring 2014.

I started working at Drake University in August 2009. Coming out of my postdoctoral position at Iowa State University in May 2009, I was active in the combinatorial matrix theory community. With the UTMOST grant award in 2010, a $525,000 4-year NSF grant to promote open-source software and open-source textbooks, I have shifted a lot my attention recently to open-source mathematics and scientific software, such as Sage.

Here is my Curriculum Vitæ. I also have a MathSciNet publication list and an arxiv.org preprint list that cover most of my publications.

In reverse chronological order, here are my papers in combinatorial matrix theory. As a general rule, I prefer to submit to open-access journals.

Many of the links below lead to Github, an online repository for open-source software. My username on Github is jasongrout, which might be helpful if you are clicking on a link below and see lots of usernames.

I have been a very active participant in the open-source mathematical software world, particularly with Sage, for over 7 years. Since I started at Drake (August 2009), I have contributed to code reviews and contributions 2,837 times on 834 separate “issues” across 43 areas of Sage, including graph theory, linear algebra, graphics, online interfaces, scientific computing packages, and many more. I also have contributed 160 peer-reviewed code contributions myself (involving adding/deleting/changing over 55,000 lines of code and documentation). This puts me in the top 15 contributors to Sage over the last 5 years out of around 700 total contributors.

In addition to working on the core Sage library, I have also worked on the following peer-reviewed projects over the last 5 years:

• Sage Notebook, an online interface to Sage: 216 code contributions adding/deleting/changing 297,931 lines. I was the lead developer for much of the last 5 years.

* Sage Cell Server, another online interface to Sage allowing anyone to easily embed live Sage computations into any webpage: 1201 code contributions adding/deleting/changing 137,441 lines. I am the lead developer and mentored 6 undergraduate Drake students who wrote and reviewed code. I also maintain the public sage cell server at https://sagecell.sagemath.org, which serves around 2,000 computations each day requested from all over the world. The cell server is used in a number of online resources, including textbooks, notes, online homework systems, and more. (Edit: As of May 2014, Andrey Novoseltsev maintains and leads development for the Sage Cell Server)

• IPython, a very popular and easy-to-use interface to Python: 59 code contributions adding/deleting/changing 3906 lines. I helped with major enhancements like their new interactive widget framework and also contributed bugfixes and smaller enhancements.

* Minimum Rank Library, a library for calculating the minimum rank, zero forcing numbers, and other related parameters on graphs: 58 code contributions adding/deleting/changing 4715 lines. I was the lead developer and also mentored several graduate students from Iowa State University who developed part of the library. This library is used by active researchers in exploring minimum rank problems.

Additionally, I contributed some peer-reviewed bugfixes and enhancements to the three.js 3d web graphics project and the online homework system Webwork.

• PyThreeJS, a wrapper around three.js to provide interactive 3d graphics for the online IPython notebook: 102 code contributions adding/deleting/changing 9452 lines. I am the lead developer and mentored 3 Drake students in this project. We have just completed the initial version, and will start promoting it for wider use as a way to do 3d graphics in the IPython notebook.

* Multi-mechanize, a suite of programs to test scalability of websites: 30 commits involving adding/deleting/changing 1191 lines.

I was awarded the 2012 Spies Prize, an annual cash award to recognize “major and inspiring contributions to the development of the Sage Mathematical Software System.”

I've labeled presentations with one of the following areas:

• research: pure math research, such as combinatorial matrix theory
• teaching: improving teaching, such as explaining ideas or helping teachers know how to use electronic resources like Sage
• technical: explaining technical infrastructure, such as how the backend of a Sage service works or the technical details of how we implemented the Sage Cell Server

• Multivariable Calculus: Ben Woodruff and I have been working on a semester-long set of problems to explore multivariable calculus, and both of us have used versions of these notes for many years. A PDF version is gradually being superseded by an online version. These problems are based on an older lecture-style set of notes by Ben and myself. Ben wrote the initial versions of both the lecture-style notes and the problem set, and then I extensively modified and edited them.
• Numerical Linear Algebra: I developed a set of problems to guide an undergraduate student through a semester course using Trefethen and Bau's Numerical Linear Algebra textbook. We used these notes in a problem-oriented course.

In June 2014, I went on academic leave of absence and worked with the quantitative finance research group at Bloomberg L.P. in New York to build software useful in quantitative finance. At the conclusion of the 2014-2015 academic year, I left Drake University to continue working at Bloomberg.

Here is a very incomplete list of articles and other things since 2014.
