Welcome!
A trip to Sentosa island, Singapore during the CDC 2023.
I'm Siddhartha, currently, a Ph.D. candidate at Systems and Control Engineering (SysCon), IIT Bombay, working with Prof. Debasish Chatterjee and Prof. Ravi N. Banavar.

I'm broadly interested in the mathematical theory of control and dynamical systems. My current focus is on:
Optimal Control (see the excellent introductory articles -- OptCon1, OptCon2); more specifically computational/numerical optimal control
Approximation theory (a nice introductory text -- CheLig:AppTheo) and its applications to optimization and control problems
Model predictive control (a nice introductory text -- GruPan:MPC); more specifically robust, stochastic, and distributionally robust MPC algorithms with emphasis on explicit and fast implementation
Differential Geometry (Lee's standard texts) and its application to optimal control problems
Probability and learning theory (see Francis Bach's notes on learning theory) and their application to control problems
Optimization algorithms, their applications in the area of machine learning and control theory, and numerical software development.
Very recently, I've developed a keen interest on optimal transport, specially discrete optimal transport and the numerical methods associated with such problems.
News and activities:
Our article titled: Data-driven distributionally robust MPC via semi-infinite semidefinite programming: an application to finance, with Souvik Das, Ashwin Aravind, and Debasish Chatterjee was accepted in MTNS (mathematical theory of networks and systems); Souvik will present it at Cambridge, UK in August, 2024.
The version 2 of QuITO --- QuITO v.2 is now out. It is more optimized, faster, solves a wide range of problems (especially singular optimal control problems), comes with an automatic change point localizationa and mesh refinement module and a GuI. Give it a try! The associated article that documents the theoretical developements can be found here: https://arxiv.org/abs/2404.13681v1.
