Janosh Riebesell
I joined the Materials Project as a staff member in early 2023 where I developed ML foundation models (CHGNet, MACE-MP) and high-throughput workflows for generating more diverse, higher-quality DFT datasets for future models.
I joined Radical AI in April 2024 to vertically integrate MLIPs and robotic labs.
In my spare time, I contribute to open source for materials informatics and help maintain pymatgen
, pymatviz
, atomate2
, matbench-discovery
, matcalc
and others.
