[00:01:42] Georg highlights the purpose of the today’s episode that includes three guests from the “CHAOTICS of the Month” series.
[00:01:56] The first CHAOTIC guest is David Lippert. He shares his background being a former software and data engineer, now in academia, and works under a Sloan Foundation grant supporting university OSPOs.
[00:05:17] Georg addresses the lack of open source awareness among faculty and encourages integration of open source into academic programs.
[00:06:37] David shares his connection to CHAOSS, joining through the CURRIOSS network of academic OSPOs and talks about working with the UN SDG Working Group to measure global impact through open source. He mentions two GWU students won a UN hackathon related to open source data management.
[00:10:56] David talks about how metrics vary based on context ( IT department vs. researcher focus).
[00:12:44] The next CHAOTIC guest is Victoria Ottah. She shares her background and her journey into CHAOSS, which is the first open source community she joined. CHAOSS provided clarity and mentorship since she was initially struggling as a designer and mentions having early support from Ruth and other maintainers.
[00:16:18] Victoria discusses the need to make GitHub and contribution platforms more welcoming to designers and suggests simplified onboarding and linking repositories to Figma or design workspaces.
[00:17:45] Victoria’s career goals and focus for 2026 is being a certified accessibility advocate to CHAOSS web projects and advocates for including people with disabilities early in the open source design and development process.

[00:21:33] The last CHAOTIC guest is Cali Dolfi. She shares her background, starting as a data science intern in 2020, and focused on community analytics. She works with CHAOSS tools Augur and 8Knot for data visualization and analysis.
[00:25:26] Cali is really excited about working in the Data Science Working Group, collaborating with researchers to explore methods for analyzing open source communities, and developing Practitioner Guides to help organizations interpret metrics effectively.
[00:28:03] Cali encourages new contributors to start by joining working groups aligned with their interests and notes that groups are small and welcoming, offering mentorship and practical work.
