Hardeep Mehta has an electrical engineering background and extensive instrument development experience. His work focuses on developing novel nuclear magnetic resonance (NMR)/magnetic resonance imaging (MRI) instrumentation that offers improved sensitivity, wider temperature handling, and extended capabilities such as in situ constant flow capability and microcoil imaging for high-field magnets. Mehta has applied years of experience with full wave, three dimensional radio frequency (RF) simulations to optimize NMR coil design, MRI, and other RF circuits.

His current research focuses on development of a microcoil design for a slowMAS (magic angle spinning) probe to study biological samples. He is also developing a high-temperature rotor for NMR experiments on battery reactions. Mehta has contributed to number of Instrument Development Laboratory (IDL) projects, involving controller design, RF circuit design, and other electronics.
