I decided to become a theoretical physicist when I was fascinated with the biographies of great theoretical physicists and science-fiction novels in middle school. However, I realized that experiments play a fundamental role in physics because all exciting theories must be tested by the experiments in my undergraduate. My first research experience was to perform ultrafast optical experiments with the guidance of my undergraduate supervisors. This valuable experience involves designing interesting experiments, solving various experimental problems, analyzing the data with reasonable models, and writing up papers. This experience had strengthened my determination to apply for graduate school in the US to pursue my academic career.

In graduate school, my theoretical physicist's dream was reinvigorated when I met my Ph.D. advisor. I realized that the most interesting part of physics research for me is to understand how experiments work and make new predictions. In particular, I was fascinated by how electron-electron interactions can dramatically change the behaviors of materials until today. I devoted the bulk of my energy to studying how electrons and holes (the lack of electrons in a fully filled valance band) interact in emerging two-dimensional semiconductors and semimetals. I found that the bounded electron-hole pairs can not only form macroscopic condensates but also dramatically change topological phase transitions.

After graduating from UT, I became a postdoc at the National Institute of Standards and Technology (NIST). At NIST, I expanded my research area to study how to control magnetic properties of nanomaterials via spin-orbit coupling enabled effects such as the spin Hall effect. To make more accurate modeling of electronic structures and spin structures, I learned many first-principles calculations tools such as Quantum ESPRESSO and Wannier90. With these tools, I was able to study various ways to induce exotic spin currents to control the magnetization in different classes of materials such as reduced-symmetry two-dimensional semimetals and two-dimensional ferromagnets, and antiferromagnets. In August 2021, I was excited to join the UAB to start my own research group with a focus on the interplay between interaction, topology, and transport. I believe that many new interesting and puzzling phenomena and materials are waiting for us to discover which never ceases to amaze me. I am also devoted to working with students to achieve their own goals.
