Supriyo Datta (http:nanohub.org/groups/supriyodatta) started his career in ultrasonics, but since 1985 has focused on current flow in nanoscale electronic devices. The approach pioneered by his group for the description of quantum transport has been widely adopted in the field of nano electronics and he was elected to the US National Academy of Engineering (NAE) for this work. This approach, combining the non-equilibrium Green function (NEGF) formalism of many-body physics with the Landauer formalism from mesoscopic physics, is described in his books. Datta is also well-known for his contributions to spin electronics and molecular electronics and received the Procter Prize (https://www.sigmaxi.org/programs/prizes-awards/william-procter/award-winner/supriyo-datta). In his latest book, Datta argues that the insights gained from nano electronics provide a new approach to the problems of non-equilibrium statistical mechanics in general (Lessons from Nanoelectronics: A New Perspective on Transport, World Scientific 2012).
