About Me

I am Zhixiong Yang (杨志雄), a Ph.D. student at the School of Electronic Science, National University of Defense Technology, advised by Prof. Jingyuan Xia and Prof. Yaowen Fu. Previously, I received my bachelor's degree from Northeastern University in 2021.

My research focuses on statistical learning and optimization for image inverse problems, including natural image and hyperspectral image super-resolution, image restoration, and radar imaging.

I am always happy to discuss research and potential collaborations. Feel free to contact me through the links in the profile or on WeChat: s1mple_21_.

Beyond Code

A few things that keep me curious, competitive, and recharged.

Sports

Move, reset, repeat

  • Gym workouts three times a week
  • Basketball, badminton, and table tennis whenever time permits
  • Exploring swimming and tennis

“Sweat is my reset button.”

Gaming

Strategy meets reflex

  • League of Legends: ARAM player
  • CS:GO and a big fan of s1mple
  • Occasionally Black Myth: Wukong and Delta Force

“Games teach resilience.”

Wanderlust

Mountains over crowds

  • Road-tripping to unseen destinations
  • Capturing moments through my lens
  • Preferring mountain trails over tourist spots

“World exploration is life's fundamental code.”
