Research Interests

• Stochastic Hydrology and Hydroclimatology
• Nonparametric functional estimation techniques (probability density Functions, regression, scenarios generation, forecasting)
• Understanding low frequency climate variability and its signatures on regional hydrology
• Incorporating climate information in water resources/hydrologic decision making
• Understanding spatio-temporal variability in Indian summer monsoon
• Nonlinear Dynamics - recovering dynamics from data
• Bayesian techniques for optimal combination of information from multiple sources and decision making

Statistical climate modeling and its application to hydrology, water resources eng. related issues; Stochastic modeling of rainfall and other weather variables; scaling issues in rainfall; Spatial estimation of hydro-climate variables; nonparametric estimation of density and regression functions for Multivariate Time series analysis of climate data; Identifying inter-annual variability in hydro climate variables and nonlinear dynamical modeling and forecasting; Inferring long range climate variability through statistical analysis of paleo proxy data.
