I am a PhD candidate at the University of Hong Kong (香港大學) under the supervision of Prof. Bruno C. d. S. Oliveira. My research revolves around programming languages, especially focusing on type systems for modularity and extensibility. I received my Bachelor's degree from Zhejiang University (浙江大学). I was an exchange student at Tokyo Institute of Technology (東京工業大学) under the supervision of Prof. Hidehiko Masuhara.

During my undergraduate years, I was the founder of ZJU Apple Club and a member of ZJU Supercomputing Team. I led the development of Qiushichao Mobile V3 for iOS, which was the most popular campus app at ZJU with 9,000+ weekly active users.

My Chinese name is 孫耀珠. Since Chinese characters are also used in Japanese and Korean, my name can be pronounced そんようじゅ in Japanese or 손요주 in Korean, both of which can be romanized as Yoju Son. If you think the Chinese romanization Yaozhu Sun hard to read, feel free to pronounce my name in Japanese or Korean style.
