My basic interest is in the areas of large sample theory and weak convergence. Recently, I have become interested in autoregressive spatial processes and I am working on the unit root or near unit root problems in the doubly geometric processes. I also have active research interest in nonlinear regression theory and statistical inference problems related to bundle strength of fibres. I have been associated with the Operations Research program in this University since its beginning and, in that connection, I participate in programs related to linear and nonlinear optimization theory.
