Assistant Prof. Razi Epsztein


Civil and Environmental Engineering

Main energy field:

Energy storage and conversion; Energy-efficient membrane separation; Recovery of valuable elements for energy production.


Ph.D. 2013 – 2017, Technion, Environmental Engineering

M.Sc. 2010 – 2012, BGU, Environmental Engineering

B.Sc. 2006 – 2010, BGU, Biotechnology Engineering

Research Area in Energy:

Our group focuses on development of membrane processes for selective separation at the water-energy nexus. In light of the growing efforts to understand and improve solute-solute selectivity in membrane processes, we strive to explore the fundamentals underlying molecular transport and selectivity in membranes and nanopores, and use the insights gained to develop selective membranes for energy-efficient separations, fuel cells, and recovery of valuable elements for energy production.

Research Interests:

Fuel Cell Technologies – Developing improved ion-exchange membranes .

Energy-efficient membranes separation – Developing solute-specific membranes to reduce osmotic pressure gradients and increase water recovery.

Recovery of valuable elements for energy production – Developing membranes to harvest valuable elements from water for energy production.
