Zahra Fakhraai

Zahra Fakhraai is an Iranian-Canadian materials scientist who is a professor of chemistry at the University of Pennsylvania. Fakhraai does research focused on glass transition, nonlinear optics, nanoparticle plasmonics, and polymer physics. She studies the impact of nanoconfinement on the structure of materials. She was awarded the 2019 American Physical Society John H. Dillon Medal. Fakhraai was one of the researchers to start laying the ground work to better understand the optical properties of glass.

Early life and education Fakhraai studied physics at Sharif University of Technology. She graduated with a bachelor's degree in physics in 1999 and a master's degree in 2001. She worked on thin polymer films and how they interact with surfaces.

Career Fakhraai was appointed to the University of Pennsylvania as an assistant professor in 2011. Specifically, she is interested in glassy materials at interfaces. Her group demonstrated that below the glass transition temperature, the interfacial dynamics of materials are orders of magnitude faster than dynamics in the bulk. They investigate how this mobile interfacial layer impacts the properties of the materials. Physical vapour deposition allows each molecule that is deposited on the surface to experience enhanced mobility, allowing them to reach their lowest energy state. She demonstrated that it is possible to make amorphous phases of glass at high density.

Fakhraai's group have developed synthetic routes to create dielectric-core gold nanoparticles. Her group have developed high resolution characterisation techniques to study amyloid aggregates in aqueous conditions.

Fakhraai was concerned about the impact of Donald Trump's travel ban and has spoken about the need to support students protected by the DACA program. She is an advocate for women in science, and has urged social scientists to consider the agency and humanity of women scientists when talking about a so-called gender-equality paradox.

Fakhraai collaborated with Tianyi Liu and Patrick Walsh, a chemistry professor. They designed and synthesised a new molecule with a perfect spherical shape. This unique molecule can never align themselves with any substrate as they are deposited. Results were these stable glasses are birefringent, a surprising result in a round material.
