He has authored about 170 papers, and has also written two books on Thermoreversible Gelation of Polymers and Biopolymers (Academic Press, 1992), and on Polymer-solvent Molecular Compounds (Elsevier, 2008). In 1990, he was awarded the Dillon Medal of the American Physical Society for his work on polymer gels. He has also founded in 1996 of a series of conferences formerly entitled Polymer-solvent Complexes and Intercalates which has been renamed POLYSOLVAT in 2008.
