Welcome to my homepage! 👋

I started my journey at Shanghai Jiao Tong University back in 2022 as an undergraduate in Artificial Intelligence. Now, I’ve taken the next big step – I’m a Ph.D. student at SJTU X-LANCE Lab, and Shanghai Innovation Institute, and I couldn’t be more excited! 🎉

My current research interests include: Spoken Dialogue Systems, Text-to-Speech, and AI for Science.

If you’re into these topics too, feel free to reach out! ✨
