He is best known for his work on self-assembling materials and supramolecular chemistry.
One of his most notable discoveries is a broad class of peptide amphiphiles that self-assemble into high aspect ratio nanofibers with extensive applications in regenerative medicine.
He has also made significant contributions to the fields of supramolecular chemistry, nanotechnology, and organic electronic materials.
He has over 300 peer-reviewed publications and was one of the 100 most cited chemists in the 2000-2010 decade.
