I have scientific interests in the following areas:

• electrical transport properties of semiconductor mesoscopic devices (conductance, tunneling, and Coulomb drag).
•  thermal properties of one-dimensional channels (thermopower, thermal conductance).
• magnetic properties of 2D magnets, especially in a graphite host (my PhD area).

In semiconductor physics I have investigated many-body effects in very clean one-dimensional channels.  These are fabricated from clean two-dimensional electron gases, as a result I have a long-standing collaboration with researchers in the Semiconductor Physics group at the Cavendish Laboratory. I have also had collaborations and written papers with researchers at the Niels Bohr Institue (Coulomb drag),  CEA Saclay (shot-noise) and UNSW (mesoscopics + pressure).

Recently we have been (i) fabricating new types of graphene samples with help of the group at the University of Manchester, and (ii) investigating quantum Hall effect in antidots with researchers at the National Physical Laboratory.
