About Me

Well, hello! 你好! 侬好! 안녕하세요! こんにちは! Guten Tag! Bonjour! ¡Hola! Olá! Ciao! Здравствуйте! नमस्ते! สวัสดีครับ! Aloha!

My name is Junjie Shen (沈骏杰). You can call me Junjie or sjj for short. I come from Shanghai, China. I obtained my Ph.D. in Mechanical Engineering from UCLA in 2022, advised by Prof. Dennis Hong. Previously, I received my B.S. in Mechanical Engineering from the University of Michigan - Shanghai Jiao Tong University Joint Institute (UM-SJTU JI) back in 2016. I am a huge fan of sports. Basketball and soccer are my favorite. I like watching movies and singing as well. Besides, I enjoy playing video games, especially Dota and CS.
