Biography
I am a second-year Ph.D. student at MIT Physics working with Prof. Nuh Gedik. I got my bachelor degree in Physics at Fudan University. My current research focuses on understanding the structral and electron dynamics in strongly correlated systems. The experimental methods include time-resolved second harmonic generation(SHG) polarimetry and time-resolved diffraction(UED, tr-XRD etc.).
Interests
- strongly correlated systems
- ultrafast dynamics

Reasearch Experience
STM study of moiré graphene and TMDC materials
Visiting Student Researcher supervised by Prof. Michael Crommie
- Characterized twisted bilayer graphene and TMDC devices ($TaSe_{2}$, $NbSe_{2}$, $TaTe_{2}$, etc.). Studied the evolution of electronic structures with back gate.
- Imaged the Mott insulating behavior of monolayer 1T-$TaSe_{2}$ with ‘flower pattern’ orbital texture.
Unconventional superconductivity in oxides
Supervised by Prof. Wei Li
- Grew and optimized oxide interfaces with pulsed-laser deposition.
- Studied the nontrivial topology of rare-earth oxide superconductor LaO with first-principle calculation.
- Analyzed the energy splitting of La orbitals in oxygen octahedron crystal fields with group theory.
CVD growth of 2D materials and device fabrication
Supervised by Prof. Faxian Xiu
- Synthesized high quality $Bi_{2}SeO_{2}$ sample using chemical vapor deposition method (CVD)
- Peeled off single-layered graphene for heterostructure fabrication.
