Lori E. Tunstall

Assistant Professor

After gaining work experience as a geotechnical engineer and construction estimator, she joined the graduate program at Princeton University, earning a joint Ph.D. in Materials Science and Civil and Environmental Engineering in 2016. Princeton University distinguished Dr. Tunstall with two awards during her graduate program, the Wu Graduate Fellowship in Engineering and Princeton’s Emerging Alumni Scholars Award for 2015 – 2016. Dr. Tunstall continued her work at Princeton University as a postdoctoral research associate for the following year, until beginning an appointment at Honeywell FM&T as a chemical engineer. Here she worked in the advanced manufacturing department, overseeing the development of processes and materials for novel applications of additive manufacturing, including direct-write electronics and direct ink write of polymers. She was selected as a part-time resident at Lawrence Livermore National Lab, where she was responsible for technology transfer between the two sites, and received the 2017 Defense Programs Award of Excellence for her contributions in solving a critical manufacturing issue.
