+In this lecture, we will be joined by **Danny Spitzberg**.
+
+About our guest speaker:
+
+> [Danny Spitzberg](https://twitter.com/daspitzberg) leads user research for a cooperative economy. He currently works with [Turning Basin Labs](https://turningbasinlabs.com), a staffing and training cooperative, and is based in Oakland, California. Over the last few years he has created an original model for user- and worker-led co-design, a more efficient and lasting approach than mainstream inclusive design. Danny's background and training is in economic sociology and experimental research, and he has done applied research for over a decade.
+>
+> His work focuses on financial security, shared ownership, workforce development, and predistributive strategies of building wealth and power. Examples of participant-led research and design collaborations include conducting human factors field work in rural India around biomass energy; developing case studies and frameworks for credit unions and other member-led organizations worldwide to build shared leadership; and facilitating co-design for California ridehail drivers to effectively file over 5,000 wage claims through a custom-build spreadsheet tool and web app, which led to a $1.3b suit filed by the state. With [Tech Workers Coalition](https://techworkerscoalition.org), Danny also co-edits a newsletter and curates an oral history project about international labor in and around the digital tech and software industry. Danny believes in stories that brings people together for collective action.
