With Daniel Branton and Haibing Peng he had worked to develop several devices pertaining to the construction of various types of carbon nanotubes.
His interests lay in developing advanced methods of physics, materials, and molecular science to achieve very rapid sequencing of the entire human genome.
Most recently he was involved with the Oxford Nanopore Group as it seeks to develop graphene and other solid state materials to achieve this whole genome sequencing.
