# Plane-wave-based density-functional theory

Most of my work on plane-wave DFT concerns the DFTK Julia code which I co-develop with Antoine Levitt and Eric Cancès from the Matherials team at Inria Paris.

# Algebraic-diagrammatic construction methods (ADC)

Part of my involvement with ADC methods is the development of the adcc python module, in close collaboration with the group of Andreas Dreuw in Heidelberg.

# Lazy matrices and molsturm

Some slides and posters introducing the molsturm and lazyten projects and how they can be used to yield a modular and flexible quantum-chemistry framework supporting rapid development of new methods.

Note, that in the first few presentations, I use the inital name *linalgwrap*
to refer to the lazy matrix library lazyten.
