Research Interests: 

Dr. Shaffer studies materials and processes for water purification and resource recovery. The goal of his research is to promote resilient communities and ecosystems through treatment processes that both create and recover valuable resources.

Currently, Dr. Shaffer investigates new membrane materials with tailored separation properties to improve desalination performance.  He employs novel characterization techniques like neutron radiography and electrochemical impedance spectroscopy to gain insight into structure-property relationships that influence membrane performance. Membranes with tailored properties will be incorporated into systems designed for high-recovery desalination of unconventional water sources.
