Current Projects: 
* Improved multistage and sequential estimation procedures; Center for Management Development Studies, Indian Institute of Management Calcutta, India. To develop shrinkage stopping rules resulting in early termination of sampling, and to consider improved shrinkage type estimators for estimating the parameters of interest. * Statistical inference using sequential and multistage methodologies; Center for Management Development Studies, Indian Institute of Management Calcutta, India. To develop the asymptotic theory in the sequential estimation of parameters for normal and exponential populations using asymmetric loss functions. Comparison of various multistage methodologies using Monte-Carlo studies. * Decision support systems for forecasting business trends and managing resource constrained projects; Ministry of Human Resources Development, Government of India. To develop new interactive software packages for decision support in the areas of business forecasting and management of resource-constrained projects.
