I am a PhD student at the University of Hong Kong (香港大學) under the supervision of Prof. Bruno Oliveira. My research revolves around programming languages. I received my Bachelor's degree from Chu Kochen Honors College of Zhejiang University (浙江大学) in 2019. I was an exchange student at Tokyo Institute of Technology (東京工業大学) under the supervision of Prof. Hidehiko Masuhara in 2017.

During the undergraduate years, I was the founder of ZJU Apple Club and a member of ZJU Supercomputing Team. I led the development of Qiushichao Mobile for iOS, which has been the most popular campus app at Zhejiang University.

My name in Traditional Chinese is 孫 耀珠Sūn Yàozhū. For your information, it is read as ソンヨウジュ in Japanese and 손요주 in Korean, both of which can be romanized as Son Yoju. If you find Chinese romanization hard to read, feel free to pronounce my name in Japanese or Korean style.
