Studies of device physics include high-Tc superconducting quantum interference device (SQUID), Josephson junctions, junction arrays, SQUID arrays, magnetometers and gradiometers SQUID Applications are focused on magnetocardiogram (MCG), nondestructive evaluation (NDE), nuclear magnetic resonance (NMR) and imaging (MRI), detection of magnetic bio-molecules, and scanning microscopy.

Other research interest are:
1.Superconducting filters and bolometers.

2.Physical properties of MgB2 films and SQUID devices.

3.Magneto-optical properties of magnetic fluid thin films.

4.Flux dynamics of (superconducting/magnetic) thin films with anti-dots.

5.Transport and thermoelectric properties of
(1)YBa2Cu3Oy/PrBa2Cu3-xAxOy superlattices, and
(2)YBa2Cu3Oy/R1-xMxMnO3 superlattices, in which R = La or Nd, M = Sr or Ca.
