Here's a new article from our group where we've found a model that describes why some grain boundaries would be able to migrate at cryogenic temperatures and why their velocities would then decrease as higher temperatures. It turns out that non-Arrhenius migration can emerge from competing thermally activated processes.

Observations of microstructural coarsening at cryogenic temperatures, as well as numerous simulations of grain boundary motion that show faster migration at low temperature than at high temperature, have been troubling because they do not follow the expected Arrhenius behavior. This work demonstrate...

Our lab is looking to hire a postdoc to work on machine learning and atomistic modeling of metallic interfaces. The opportunity comes with full funding and conference travel.

Candidates must have a Ph.D. in materials science, mechanical engineering, computer science, or a related field with a solid background in general materials science. While experience in particular computational techniques or materials systems is not necessary, a strong background in computational materials science and/or computer programming is required. Excellent written and oral communication skills are essential.
Experience with machine learning methods and the LAMMPS molecular dynamics software is desired. Fluency in Python and MATLAB programming is a plus.

Only candidates with any/all the above-mentioned experience will be considered.
