Ruben's research involves the molecular engineering of polymeric and ceramic materials for advanced water purification applications. Ruben uses block copolymer materials - particularly vertically-oriented cylindrical phases - as templates for generating nanoporous composites. A major interest is in using vertically-oriented block copolymers as selective templates for the growth and nucleation of photocatalytic oxides using sequential infiltration synthesis (SIS). Photocatalytic functionality enables membranes to actively downgrade pollutants into safer compounds, and can be used for self-cleaning materials. Ruben is advised by Argonne National Labs Staff Scientist Dr. Seth Darling, and has a pro-forma appointment in Professor Paul Nealey's group.
Ruben grew up in New Jersey and has always been interested in engineering across length scales and the impacts of technology on the environment and society. Ruben received his B.S.E. in Materials Science and Engineering at the University of Pennsylvania, where he worked on the electronic transport properties of low-dimensional nanomaterials. In particular, Ruben has worked on the size-property relationships in molybdenum disulfide nanotubes at the Weizmann Institute of Science in Rehovot, Israel. He has worked on both carbon nanotube and granphene biosensors at Penn, and has developed graphene technologies at Graphene Frontiers LLC in Philadelphia.
