The main research interest lies in the study of the electronic structure of disordered alloys. The Augmented Space Technique to deal with disorder was proposed by Mookerjee as early as 1973. Coupled with the TB-LMTO and the recursion method of Haydock et.al.the technique has been developed into a powerful computational tool.

      It enables us to study clustering, segregation, short-range ordering and local lattice distortions due to size mismatch. Coupled with the cluster-variation technique and the orbital peeling method of Burke, we can study the phase stability and phase diagram of binary and ternary alloy systems.

      An extension of the method allows us to study systems with potentials which vary randomly with time.

      A recent interest is the extension of the method to deal with response functions and generalized susceptibilities in random systems.

The group is also interested in rough surfaces, catalysis and electronic and magnetic properties of finite clusters
