Summary
👤
Senior🎓
Top SchoolJohn Mangeri is a postdoctoral researcher and computational materials modeler with 11 years of experience probing multiferroic and dielectric behavior from the atomistic to nanoscale using DFT (VASP, GPAW) and finite-element methods (MOOSE). He leads development of Ferret, a MOOSE application, and contributed foundational RankThreeTensor support to the widely used idaholab/moose framework to enable higher-order multiphysics simulations. His work, funded by Marie-Curie and DOE awards, translates first-principles physics of materials like BiFeO3 and GaV4Se8 into coarse-grained, experimentally relevant models for energy harvesting, photonics, and information processing. Based in Copenhagen, he blends deep computational physics with production-grade code development, uniquely straddling scalable simulation infrastructure and atomistic insight.

Contributions summary:John primarily focused on implementing and refining tensor support within the MOOSE framework. Their contributions involved adding initial support for RankThreeTensor, including core functionalities like initialization, operator overloading (addition, subtraction, multiplication, division), and L2 norm calculation. Furthermore, the user made updates to adjust for the required tensor size. These changes are crucial for supporting multiphysics simulations that require higher-order tensor representations.
