Hi, I’m Qingyu Liu (刘庆宇). I am currently a Master of Science in Engineering (MSE) student in Electrical and Computer Engineering (ECE) at Johns Hopkins University, where I am affiliated with the Smile Lab at the Center for Language and Speech Processing (CLSP) under the supervision of Prof. Berrak Sisman and Prof. Philipp Koehn. I also work as a research assistant at Shanghai Jiao Tong University X-LANCE Lab under the supervision of Prof. Xie Chen. I completed my undergraduate studies at Shanghai Normal University under the supervision of Prof. Yanhua Long.

My research interests are in speech, generative models, machine learning, and deep learning. Currently, I focus on:

• Text to Speech
• Speech Translation

I’m a Manchester United fanatic, and my dream is to see them conquer the Premier League once more. Feel free to reach out if you want to talk footy! Manchester United always let their loyal fans down.
