Peiyao Wu – (2021-present) – PhD student – Email: peiyao.wu@berkeley.edu
Peiyao’s research focuses on nano and microparticle behavior at interfaces. She aims to explore nanoparticle adsorption and interactions at oil-water interfaces from both experimental and computational perspectives. Currently she is applying these principles to study microplastics stability and their interaction with lipid bilayers.
Degrees: B.S. in Mechanical Engineering, Georgia Institute of Technology, Atlanta GA
B.S. in Applied Mathematics, Emory University, Atlanta GA.

Devin Schinski – (2022-present) – PhD student – Email: devin_schinski@berkeley.edu
Devin’s research focuses on studying concentrated aqueous electrolytes at electrode interfaces. His work endeavors to better understand the effects of confinement on the structure and dynamics of the electrical double layer.
Degrees: B.S. Chemical Engineering, University of Illinois Urbana-Champaign, Urbana, IL

Margaret Shen – (2022-present) – PhD student – Email: mdshen@berkeley.edu
Margaret’s research focuses on the interfacial interactions and characterization of ionomer thin films in fuel cells. Her research works to understand the structure-property relationships of thin-film ionomers in order to improve their functionality.
Degrees: B.S. in Chemical Engineering, University of Wisconsin-Madison, Madison WI

Rebecca Wheeler – (2023-present) – PhD student – Email: rebeccaw@berkeley.edu
Rebecca’s research in collaboration with Dow Chemical focuses on programmable de-adhesion. Her research endeavors to develop a method to remove adhesives to increase the efficacy of recycling.
Degrees: B.S. in Chemical Engineering, UC San Diego

Jack Reardon – (2024-present) – PhD student – Email: jack_reardon@berkeley.edu
Jack’s research focuses on understanding the structure and dynamics of concentrated water-in-salt electrolytes. His research aims to understand electrolyte material properties under confinement.
Degrees: B.S. in Chemical Engineering, The Ohio State University in Columbus Ohio
