Welcome! |
I am currently a PhD student (2019–) at the Applied Physics & Applied Mathematics Department in Columbia University. I work as a graduate research assistant with Professor Renata Wentzcovitch.
I got my bachelor degree from Nanjing University (2013–2017), and master degree from Columbia University (2017–2018).
My research interests lie broadly around the intersection of physics and computer science. My current research focuses on investigating physical properties of Earth-forming materials under finite pressure and temperature with ab initio calculation and deep-learning potential molecular dynamics.
δ-AlOOH is a high-pressure mineral with a wide stability field. This study investigate the effect of pressure on the hydrogen-bond disorder in δ-AlOOH. Our study suggests the disorder and tunneling of those hydrogen bonds are connected with observed anormalies in earlier experimental and computational studies.

Deep-learning potentials enable us to perform large-scale molecular dynamics on GPU-accelerated machines with ab initio acuracy. Using these advanced technique, we study various properties that are unique to these hydrous phases (ongoing).

This study introduces the cij
Python package. This package implements the SAM-Cij formalism that computes the elastic properties of solids under mantle pressure and temperature.

This study investigates the change in second-order elastic constants under induced stress / strain. Our results show the changes in second-order elastic constants are connected with third-order elastic constants and pressure derivative of second-order elastic constants.

Sheet hydrous minerals are abundant in subduction zones, they exhibit significant anisotropies.
