Biography
Han LIU is a materials physicist who is combining computational simulations and machine learning techniques to accelerate materials’ inverse designs for wide-range engineering applications. He obtained his Ph.D. from the Department of Civil and Environmental Engineering at University of California, Los Angeles (UCLA) in 2021, and concurrently obtained a master’s degree from the Department of Electrical and Computer Engineering at UCLA in 2020. Prior to UCLA, he obtained his bachelor’s and master’s degrees from the College of Polymer Science and Engineering at Sichuan University (SCU, CHINA) in 2013 and 2016, respectively. Since 2022, he works as an Associate Professor in the Department of Polymer Processing Engineering at Sichuan University (SCU, CHINA). Prior to the faculty of SCU, he worked as a Postdoctoral Associate in Physics of AmoRphous and Inorganic Solids Laboratory (PARIS Lab) at UCLA.
His researches combine computational simulations and machine learning to accelerate the design of disordered materials, including glassy materials, porous materials, and mechanical metamaterials. So far, he has published 25 scientific papers, including 15 first-author publications. His present research interest lies in the intersection between machine learning and computational materials. By developing the cutting-edge techniques and theories of artificial intelligence (AI), he systematically investigates the AI-computing methodologies for materials modeling and inverse design and, ultimately, aims to build an advanced AI-computing platform for polymer processing (and materials design in general).
