This year, Tracing Architecture is teaming up with the AIA Arizona State Conference to create a special set of episodes. During the conference, local leaders of the design community will be leading conversations with each of the conference speakers, and Tracing Architecture is sitting down with those members of our design community to learn more about them and how they are connected with their respective conference speakers. In this episode, the second of three special episodes for the conference, we'll be speaking with: Darren Pettrucci, AIA, founder and principal of AIR (Architecture-Infrastructure-Research) and professor in The Design School at Arizona State University; and Claudia Kappl Joy, co-founder, creative director and managing director of CLL . Concept Lighting Lab, an architectural lighting design studio in Tucson.
