Andrew J. Milne PhD

Tech consultant, author, public speaker, PhD, patent-holder, Stanford University lecturer and researcher. Andrew Milne has been deeply involved in exploring the intersection of emerging technologies and future needs for over 20 years. He has contributed to technology systems planning and design for new and existing building projects at more than 180 academic campuses around the world. Now as an educator and technology consultant, he applies his research-informed background to design thinking, and his multi-faceted perspective to teaching, learning, and technology.

Earning his Ph.D. in Engineering at Stanford University’s Center for Design Research, Andrew developed and evaluated pervasive computing collaboration technologies to support distributed engineering design teams. He went on to apply the insights and methodologies he developed at Stanford to inform his work in the commercial sector as co-founder of the Silicon Valley collaboration hardware and software firm Tidebreak, both as a technology developer and consultant. Dr. Milne has also contributed to the discourse on learning space design as an author, presenter, and volunteer. He was on the team that wrote the first version of the ELI Learning Spaces Rating System, and has both written and presented forward-looking perspectives on learning technology topics for EDUCAUSE, SCUP, NACUBO, Campus Technology, AVIXA, and other education-oriented conference events.
