Project: Frost damage in concrete
Research Interests
• Broad interests in materials science
• Understanding how fundamental processes (e.g. chemical interactions between surfactants and cementitious/pozzolanic materials) affect the frost protection of concrete
Biography
Lori has been a postdoctoral research associate in George Scherer’s Materials Research Group since June 2016. She received her Ph.D. in Civil and Environmental Engineering and Materials Science from Princeton University in May 2016. Her dissertation was entitled “A study of surfactant interaction in cement-based systems and the role of the surfactant in frost protection.” Lori decided to pursue a career in research because she loves problem solving.
