Bio

Nishanth Gadiyar is an Electric Machinery Design R&D Staff Member with the Energy Science and Technology Directorate (ESTD). He holds the Alvin M. Weinberg Distinguished Staff Fellowship and is affiliated with the Electric Drives Research Group within the Buildings and Transportation Sciences Division (BTSD). 

His ongoing research develops high-performance and sustainable electro-mechanical systems for energy conversion and motion control. His research has applications to electric cars and trucks, off-highway vehicles, airplanes and ships, manufacturing industries, HVAC equipment, semiconductor manufacturing, energy storage using flywheels, and power generation.

Nishanth received his Ph.D. from the University of Wisconsin–Madison, where he was advised by . His dissertation research focused on developing torque-dense and power-dense axial flux electric machines to electrify off-highway vehicles, and led to the development of:

  • One of the first high-power, high-speed integrated electro-hydraulic machines to electrify off-highway vehicles.
  • A multi-physics optimization technique for co-design of the integrated electro-hydraulic machine.
  • One of the earliest additively manufactured electric machine stators with complex lamination-emulating geometry and 6.5% silicon steel, including experimental performance characterization.
  • A technique to design electric machine windings capable of controlling any spatial harmonics in the airgap, including demonstration of the torque density improvements using these controlled harmonics. 

Note: In Feb 2025, Nishanth changed his name from Fnu Nishanth and it's variants (Nishanth / Nishanth Nln etc) to Nishanth Gadiyar.
