Ph.D Candidate

About Me

I am a researcher with interests spanning the fields of ocean and atmospheric sciences, climate change, ship routing, development in resource constrained economies, public policy and education. I focus on developing fundamental knowledge and utilizing those to build usable systems that solve practical problems. Currently, I am wrapping up my Ph.D. at MIT working in a highly inter- and multi-disciplinary environment. My research combines elements of ocean sciences, computational engineering, stochastics and optimal control. I have developed a probabilistic regional ocean prediction system, optimal vehicle guidance schemes, and advisory services for sustainable fisheries management in India.

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.
