I am interested in statistical methodology and applications investigating phenomena on natural events that evolve over space and time. Of particular interest are natural hazards, environmental variables and diseases. The statistical problems are wide rannging and complex. My immediate interests fall into the following categories-

1. Modelling of spatial and temporal stochastic dependence structures.
2. Efficient computation of big spatio-temporal dependence matrices.
3. Applications involving the above.
