Craig B. Arnold is the Vice Dean for Innovation at Princeton University. The role aims to strengthen the University’s capacity to engage with entrepreneurs, alumni, industry, technology investors and other potential partners.

Arnold is Princeton's Susan Dod Brown Professor of Mechanical and Aerospace Engineering, and served from 2015 through 2022 as the director of the Princeton Materials Institute. He leads a vibrant research program that ranges from basic science to applied technology aimed at developing a deeper understanding of materials synthesis and processing in areas including advanced manufacturing, energy storage and conversion, and optics and photonics. 

Arnold holds 15 granted patents, and is the co-founder of two companies based on research conducted at Princeton. TAG Optics Inc. developed the TAG lens and was later acquired by a major precision instrument manufacturer. Invictis Technologies is working to create a safer and less painful automated intravenous injection device. In preparation for launching both companies, Arnold and his team participated in I-Corps programs to explore the potential of technologies developed in university laboratories.
