Background

Dr. Dingreville joined the Woodruff School as an adjunct assistant professor in 2019 and is based at Sandia National Laboratories.

Research

  • Mechanical behavior and aging of materials under extreme environments (e.g., irradiation or high strain rate), with an emphasis on characterizing the impact of coupled effects (e.g., stress and irradiation) on properties and microstructure evolution.
  • Materials design through interface engineering to enhance performance under extreme environments.
  • Atomic-scale defect mechanisms and collective response of interfaces under extreme environments.
  • Integration of computational materials science simulations with experimental capabilities (simulated experimental measurements).
My research expertise is at the intersection of computational material science, experimental materials science and emerging fields in integrated computational mechanics. I employ and combine various theoretical and computational techniques (molecular dynamics, cluster dynamics, phase field, mean field, data mining) to understand and characterize materials aging and performance in solid matter. My research emphasizes designing materials with enhanced functionality through understanding and control of interface and defect phenomena. My research strategy is built on “reduced order mesoscale models”, which enable insights into how computational materials science and engineering can be exploited as discovery tools for applications into technologies such as nanostructures or advanced alloys.
