My research interests include: 1) probing the mechanical properties of materials (with a focus on nanostructural materials); 2) developing technology to enable these investigations, and 3) determining the relationship between macro-scale and nano-scale mechanical properties by understanding the underlying physical mechanisms. Currently my research efforts are focused on applying and developing unique quantitative in situ transmission electron microscopy deformation techniques (indentation/compression/bending/tensile). While obtaining my Ph.D. from the University of Pittsburgh I focused on the deformation mechanisms of nanocrystalline Ni (Shan at al, Science, 2004; Shan et al. PRL, 2007; Shan et al, PRL, 2008). As a postdoctoral fellow at the National Center for Electron Microscopy at LBL, Berkeley, CA, I worked on a new quantitative in situ nanoindentation holder, where our findings on the initial plasticity of Al grains were published at Nature Materials in 2006. Another two discoveries stemming from my postdoctoral work were published at Nature Materials (Shan et al, Nature Materials, 2008; Shan et al, Nature Materials, 2008). From 2006 to 2009, I worked as a senior scientist at Hysitron, Inc., where I lead the development of in situ TEM techniques in the R&D program. As a principal investigator, I was granted a SBIR Phase I&II grant ($850K) by US Department of Energy titled Quantitative in situ TEM tensile apparatus. In year 2009, I was appointed as Cheung Kong Professor at Xi’an Jiaotong University and became the winner of National Outstanding Youth Science Foundation. In year 2010, the first paper after I joined Xi’an Jiaotong University was published in Nature (Yu et al, Nature, 2010).
