Sustainability in materials and manufacturing can be categorized into three aspects:
  • Circularity (recycling) of materials/components
  • High performance and tolerant materials, durable in harsh environments 
  • Energy and resource efficient manufacturing technologies
In particular, development of sustainable materials that can withstand harsh conditions is one of the basis for technological advancement in modern society. Lightweight, high performance, and minimal need for service and maintenance are among key factors for developing such materials. The main step for design and development of modern materials is to understand the relationship between the microstructure and material behavior. This can reveal the "weak-points" in the microstructure, by tailoring of which, it is possible to develop high performance, durable and light materials. Important to always consider recyclability of the materials, to target circularity also. The key is to design materials  that are "tolerant" to impurities that come in from recycling, or choice of manufacturing technology: "tolerant alloys". 
In general, our main research focus is on the relationship between microstructure and (thermo) mechanical properties of metallic materials. More specifically, I emphasize on metallic materials design and development based on advanced characterization techniques to investigate (thermo)mechanical behavior in complex/harsh working conditions. To complete the chain of knowledge transfer into real applications, the final goal in our research is to bridge the experimental knowledge and finite element simulation, for process optimization as well as material properties prediction and optimization.
Specifically, our daily research work is within Physical & Mechanical Metallurgy, Microstructure-Properties relationship, Failure Analysis, Electron Microscopy (SEM, EBSD, EDS, WDS, FIB/SEM, ...), Micro/Macro Metal Forming, Thermomechanical Processing, Heat treatment, Metals Deformation, Materials Characterization, Precision Engineering, Numerical and Analytical Modeling. Electron microscopy and related analytical methods are our research hobbies.
