He has extensive experience in the use of advanced characterization techniques to understand and manipulate functional oxide heterostructures, nanostructures, and interfaces. His current goal is to create a pathway to use high-quality oxide heteroepitaxy for soft transparent technology. Now, he is a pioneer with the most publications in this research direction. He has published >370 papers (Google Scholar: >35000 citations, h-index=89) in academic journals.
