Awards & Honors:
Dr. Shaffer studies materials and systems for water treatment. His research aims to create new and resilient water supplies through desalination technologies and reuse strategies.
Currently, Dr. Shaffer investigates membranes for desalination and tailors membrane surface properties to improve performance. He employs novel characterization techniques like neutron radiography and electrochemical impedance spectroscopy to gain insight into structure-property relationships that influence membrane transport. Membranes with tailored properties will be incorporated into systems designed for high-recovery desalination of unconventional water sources.
