In this issue of e-SPAN, we say farewell to Mary-Lou Arscott, Associate Studio Professor and Associate Head for Design Fundamentals, who retired this spring after 18 years with the school. We include the story of her unconventional architecture path in her own words. We also share images from this year's spring thesis exhibition, commencement and the inaugural Building Performance and Diagnostics Symposium which took place at CMU in April.
