Research Assistant
Adam works on improving machine learning methods for magnetic fusion devices, namely i) developing models for core-edge integration in tokamaks based on experimental and simulation data ii) improving the workflows of ML researchers in fusion by developing standardized data accessing/publishing methods.
Adam is part of the materials science department and works under a EUROfusion eneabling research grant for machine learning on power exhaust in tokamaks. However, he is closely involved in the ACH through collaboration with Aaro Järvinen on applications of Bayesian methods for uncertainty quantification and validation of predictive models in fusion plasmas, as well as with Jukka Nurminen and Fran Jurinec on the development of feature storage framework for improving machine learning workflows within EUROfusion.

Project Manager
The Sparselizard open-source C++ finite element (FE) library provides a framework for numerical implementation of multiphysics systems and domain-decomposition capabilities for high-performance computing. The collaboration aims to take advantage of these for numerical simulation of models describing the scrape-off layer (SOL) plasma.
Rahul's current work involves implementing FE algorithms to simulate SOL plasma in a self-consistent manner. Rahul's specialization is Multiphysics simulations surrounding Computational Fluid Dynamics. His background is Computational Mechanics.
