Matthew Peters works on creating thermodynamic databases and models via the CALPHAD method. Using experimental data from the literature, along with first-principle calculations, he is able to determine the Gibbs free energy curves of relevant phases. These free energy curves can be used to create and predict phase diagrams that are often fundamental to any ICME (Integrated Computational Materials Engineering) project. He has worked through CHiMaD on silicon based in situ composites and is currently working with QuesTek LLC on the design and optimization of thermoelectric materials.

Matthew came to Northwestern after spending two years teaching elementary science in New Orleans through the Teach for America program.  His interests lie in research, communication, and leadership.  He has served as President of the Materials Science Student Association (MSSA), a Materials Engineering Intern at SpaceX, and currently teaches weekend courses at the Northwestern Center for Talent Development.
