Haoxiang Sun
Hi there 👋, I’m Haoxiang Sun (å™æµ©ç¿”), a 4th-year undergrad at Renmin University of China, pursuing a dual degree in CS and Finance. My research focuses on Language Models. I am currently visiting UC Berkeley, fortunate to work with Sewon Min. Previously, I had a great time working with Manling Li and Zihan Wang at Northwestern, and with Xin Zhao at Renmin.
During my visit, I took CS 288: Advanced NLP (A+, highest score among ~150 students, taught by Sewon Min and Alane Suhr) and CS 294-258: Computational Models of Language Use (A+, top 4 out of ~25 students, taught by Alane Suhr).
Note: My UC Berkeley email hxiang.sun@berkeley.edu will soon be deactivated. Please reach me at hxiang.sun@gmail.com.
One of my favorite things about living in the Bay Area is exploring on foot and by public transit (BART, Caltrain, Muni, and more). A go-to adventure of mine is taking BART to Powell Street Station, walking through Chinatown up to Fisherman’s Wharf, and then strolling along the waterfront all the way back to Embarcadero Station. I also love riding buses across the Richmond-San Rafael Bridge, the Golden Gate Bridge, and the Bay Bridge. Another frequent trip of mine is taking Caltrain from San Francisco all the way down to San Jose, grabbing a seat on the upper deck and enjoying the scenery along the way. I’m also a big fan of the vibe around Ocean Beach in San Francisco. When I’m not out exploring the Bay Area, I also enjoy playing Minecraft, especially on the Hypixel server, where my favorite game modes are Capture the Wool and Bed Wars (particularly Rush and Castle 40v40).
