Education and Career
Arnold attended Haverford College, where he majored in mathematics and physics. As an undergraduate, he worked with Jerry Gollub in fluid mechanics and was captain of the track and field and cross-country team.[5] He earned a bachelor's of science degree in 1994.
He then studied experimental condensed matter physics with Michael Aziz[6] at Harvard University, where he earned his Ph.D. in 2000. He was a postdoctoral researcher for two years at the Naval Research Laboratory prior to joining Princeton in 2003.[2]
One of his inventions, the tunable acoustic gradient index of refraction lens, or TAG lens, was the basis for founding TAG Optics, Inc., which was later acquired by Mitutoyo Corporation, a precision instrument manufacturer based in Japan.[4] He has co-founded three other companies based on technologies invented in his Princeton lab.
From 2015 to 2022, Arnold served as director of the Princeton Materials Institute. In 2022, he became Princeton's vice dean for innovation,[7] heading the Office of Innovation. In that role, he has led the launch of a workforce hub and a regional photonics consortium[8] and played a founding role in the NJ AI Hub.[9][10]
Arnold is a fellow of the Society of Photo-Optical Instrumentation Engineers and Optica, formerly the Optical Society of America. In 2017, he received the Edison Patent Award from the Research and Development Council of New Jersey for the invention of TAG lenses.[1] In 2025, he received the R&D Council's Catalyst Award for leadership developing New Jersey as a hub of innovation.[11]
He has published more than 200 scientific papers and book chapters.[12]
