Ph.D., The University of Texas at Austin, 2021

Research Interests

My research interests include exploring low-dimensional quantum materials’ novel properties via various electrical and optical techniques. During my Ph.D., I mainly focus on nanoscale imaging of photo-excited charge carriers’ dynamics and correlated states in 2D quantum materials using MIM. Building upon my previous work, I am currently interested in understanding and controlling ultrafast dynamics in low-dimensional materials.
