This grant supports Ekaterina Holdener at St. Louis University who is establishing an Open-Source Software Center (OSS Center) at the university that will, among other activities, launch a program to facilitate graduate students and undergraduate student participation in faculty-driven open-source research software projects. Over the grant period, Holdener anticipates that the new program will allow at least 120 student contributors to support some 30 faculty-driven software projects. Additional funds will pay for a host of other activities designed to support the new OSS Center, including the development of organizational infrastructure and systems, requirements and design checklists, the publication of a playbook of OSS Center-related activities and programs on building open-source software capacity in university settings; and the training of an estimated 16 graduate student in computer science, data science, and software engineering. Funds will provide financial support for Holdener, 16 graduate student employees, and a full-time program director.
