Oren is the Director of the Melville Laboratory for Polymer Synthesis at the Department of Chemistry, University of Cambridge. His research group are interested in studying supramolecular polymers, hydrogels and composite materials and their dynamics of assembly in an aqueous environment. Prior to moving to Cambridge, Oren worked on supramolecular polymers, at the Eindhoven University of Technology with Professors E. W. (Bert) Meijer and Rint P. Sijbesma after he finished his PhD under the supervision of Professor Robert H. Grubbs at the California Institute of Technology (Caltech) in Pasadena, California in 2004.
