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.

Summer Interns

We host only the following type of summer interns: (a) Selected through the Indian Academy of Sciences Summer Research Fellows Program; (b) as part of existing collaboration with PIs; (c) candidates who demonstrate exceptional coding skills above and beyond coursework and online self learning.

General word of advice:

Generic emails stating that you have completed a particular online course does not inspire confidence in professors. It is better to share the git repository of particular projects that you worked on. Faculty around the world recieve 100s of emails from Indian students on a weekly basis and most do not read because all emails look the same. Please improve your skills and show evidence (in the form of code!) that you are skilled. Also remember when you send the same email to everyone that faculty in the same department/institute talk to each other!!!
