Collaborations
My collaborations span across the disciplines and include application scientists, mathematicians and computer scientists alike. Recently I have joint multiple interdisciplinary research initiatives in which I take a mediating role between the involved communities, for example by providing interdisciplinary software platforms, such as the Density-Functional ToolKit (DFTK), in which our efforts can be bundled in one code base.
Member in cross-departmental initiatives
-
Center for Exascale Simulation of Material Interfaces in Extreme Environments, Massachusetts Institute of Technology.
Research initiative advancing state-of-the-art first-principle simulations by connecting method development with (a) advances in programming languages, compiler technologies and performance engineering tools and (b) underpinning them with rigorous approaches to statistical inference and uncertainty quantification (UQ). On the former aspect I collaborate with the JuliaLab of Alan Edelman to developing a composable automatically differentiable software for molecular dynamics simulations and on the latter with the group of Youssef Marzouk on uncertainty quantification in first-principles simulations. -
Accelerated Computational Electrochemical systems Discovery, Carnegie Mellon University, Julia Computing and Citrine Informatics.
Project centred around discovering novel materials for electrochemical catalysis and lithium batteries based on high-throughput screening. The developed workflow includes novel numerical methods, surrogate modelling for electrocatalytic reaction networks, advances in data warehousing and analysis and the integration of automatised experimental pipelines. I collaborate with the group of Venkat Viswanathan on developing a first-principles screening pipeline for novel battery electrolytes. -
Extreme-scale Mathematically-based Computational Chemistry, Sorbonne University, Inria Paris and École des Ponts ParisTech.
Interdisciplinary initiative to advance the state of the art in first-principle simulations by integrating recent advances in numerical linear algebra (e.g. low-rank factorisations, randomised methods, GPU acceleration) and numerical analysis (e.g. a posteriori error estimation) into state-of-the-art molecular-dynamics and electronic-structure methods. Continuing from my PostDoc I participate in the development of black-box density-functional theory methods and a posteriori error estimates, mainly working with Eric Cancès and Antoine Levitt.
