I have been using participatory design methods and research through design since I started working as a research scientist at the University of Pittsburgh in 2005.  The methods learning on those projects, where we collaborated with School of Design Faculty from Carnegie Mellon University, became my standard practices in research.  I began writing about this practice, and how it relates to the learning sciences in 2013.  In 2017 I co-edited a book on participatory design and how it is practiced by learning scientist with Jason Yip, Elizabeth Bonsignore, and Carl DiSalvo; Design for Learning: Perspectives from Practice and Research.
