About Me

The goal of our research is to build holistic science-based data-driven computational solutions to complex engineering and environmental problems. Example applications include climate change, sustainable fisheries management, cyclone predictions, coastal hazard management, and optimal vehicle routing. Pursuant to our goal, we develop, implement and apply fundamental theories, numerical schemes and software systems.

Research Interests

Ocean Modeling

Development and applications of stochastic and deterministic primitive equation ocean modeling systems.

Computational Engineering

Development of novel numerical schemes and software systems for computational fluid dynamics, especially stochastic PDEs and parallel computing.

Uncertainty Quantification and Analysis

Probabilistic predictions and optimization utilizing dynamic stohcastic model order reduction schemes (e.g., Dynamically Orthogonal Field Equations).

Optimal Vehicle Guidance

Combining state of the art environmental state forecasts (ocean, atmosphere, traffic etc.) with fundamental planning PDEs for time-, energy-, risk- optimal path planning of ships, AUVs, drones, cars etc.

Data Assimilation

Combining Models and Data for Geosciences and Climate Studies.

Designing for Resource-Contrained Economies

Cost-effective designs of practical and usable engineering solutions to societal problems in resource-contrained economies such as India. e.g., Potential Fishing Zone Advisory for marginal fishermen, disaster mapping and risk mitigation strategies for coastal cities.

Opportunities

Master's and Ph.D. Students

We invite students who are interested in any of the following topics: numerical solution of stochastic partial differential equations, uncertainty quantification, Bayesian and deep learning of dynamical systems, fluid dynamics of the atmosphere and oceans, and path planning of autonomous vehicles in dynamic environments.

Research Staff

We invite applications for a contractual 1 year research staff position. Primary responsibilities include server management, taking care of tenders, purchase orders, complying with IISc rules. Candidates interested in our research problems can also contribute to ongoing projects.
