Biographical Statement

Yalin's PhD research focused on designing material transitions in polyelectrolyte complexes (PECs). She was jointly advised by both Prof. Sarah Perry and Prof. Maria Santore. Her work included exploring polymer backbone chemistry as a strategy for modulating the material properties of PEC-based materials. She also examined polyelectrolyte complexation between silica nanoparticles and oppositely-charged polymers. In her free time, she enjoys reading and drawing, and when weather is nice, swimming and skiing.

Yalin participated in an internship in fall 2018 with BASF in Wyandotte, MI.

Dr. Yalin Liu successfully defended her PhD dissertation on Designing Material Properties in Polyelectrolyte Complexes on February 14th, 2020. Dr. Liu was the second PhD student to graduate from the Perry Lab! She has since moved on to the leadership rotation program at Henkel, after which she joined the Laundry and Home Care Team.
