I am a Ph.D. student in the Electrical and Computer Engineering Department of UC San Diego. I am currently working in Existential Robotics Lab under the supervision of Prof. Nikolay Atanasov. My research interest is broad and multidisplinary. Currently, I focus on perception and mapping. Before this, I also explored other research topics like path planning, large language model. Yeap! I am a fan of intelligent systems like robots!

Prior to my studies at UC San Diego, I received my B.S. degree in the Physics Department of Fudan University. During my undergraduate, I did research mainly in two areas, design and implementation of experiment systems for physics and SoC (System-on-Chip) software development. I like to share ideas and experiences with others. Please feel free to explore this website and reach out to me if you like to discuss with me.
