Description of Scientific Projects

Professor Gupta leads the Data Assimilation Group (DAG) which investigates the philosophy, theory and practice of building, calibration and application of mathematical models, and how to merge quantitative, fuzzy and/or qualitative data with models. He encourages students to understand and question conventional scientific wisdom, to examine underlying assumptions, to draw from ideas in other disciplines, and to think “outside the box.” The DAG has made contributions to the theory and practice of model calibration (including multi-criteria and Bayesian methods for assimilating information from data), model structure estimation, global optimization, parameter sensitivity analysis, and artificial neural networks. The group is also keenly interested in the application of emerging and futuristic technologies to hydrologic science, including for example distributed and embedded sensor networks, parallel processing computational tools, and multi-satellite sensors.
