“Road ahead is long and hard. Persist, success is in card. Being a dreamchaser at Westlake, Achieving new progress with Westlakers“
Biography
Shi Liu graduated in 2009 with a B.S. in Chemical Physics from the University of Science and Technology of China, before completing his Ph.D. from the University of Pennsylvania in 2015. Dr. Liu was offered a Carnegie Fellowship at the Carnegie Institution for Science in Washington, D.C., where he worked on multiscale simulations of defects in ferroelectrics and hybrid perovskites for photovoltaic applications. He received the American Physical Society Nicholas Metropolis Award in Computational Physics in 2017 and SEDD (Sensors and Electronic Device Directorate) Distinguished Fellowship at U.S. Army Research Laboratory in 2018. In June 2019, Dr. Liu joined the School of Science at Westlake University.
Research
The overarching theme of our research is to develop and apply predictive multiscale computational approach that combines formerly isolated methods to enable accurate and efficient estimations of materials properties at technologically relevant length/time scales.We comprehend the structure-property relationships of current state-of-the-art materials and then use these insights to guide the design of advanced materials. Research areas in our lab are in:
1. Novel ferroelectrics for next-generation energy and information technology.
2. Topological phases in condensed matter physics.
3. Deep-learning-based large-scale modeling of complex oxides.
