Mengqi Lei (雷孟奇)
I am a PhD student at the School of Software, Tsinghua University, advised by Associate Professor Yue Gao. I joined the doctoral program in 2025 and am a member of iMoon-Lab.
About Me
My research interests lie in visual intelligence and multimodal learning. I work on vision-language models, vision foundation models, object detection, object counting, high-order representation learning, etc. My objective is to develop a more general, comprehensive, and efficient framework for visual and multimodal representation learning.
