"[2] As an author, his books and online courses are widely used as original research and design work in the field of nanotechnology and electronic devices.

[2][3] He is known for the development of the spin transistor, the non-equilbrium Green's function method for quantum transport and negative capacitances.

[7] In a series of papers between 1985 and 1995 his group demonstrated how the non-equilibrium Green's function (NEGF) formalism used by many-body physicists for uniform conductors could be extended to model electronic devices which are non-uniform and have contacts.

This "proposal planted the idea that spin could be used in its own right as a means to carry and manipulate information — and gave birth to the new field of spintronics.

"[10] In 2008, along with Sayeef Salahuddin he proposed the concept of negative capacitance devices,[12][13] which is now considered a prime candidate for reducing dissipation and extending Moore's law.

[2] In 2012, he was elected as a member into the National Academy of Engineering (NAE) for quantum transport modeling in nanoscale electronic devices.
