About Me
Hi, my name is Qixin Hu (胡琪鑫). If you can't read Pinyin, you can pronounce it as "Chee-sheen Who." I am a second-year Ph.D. student at USC, working with Prof. C.-C. Jay Kuo. Currently, I am an Applied Scientist Intern on the Agentic AI Team, Amazon Web Services (AWS). Previously, I was a Research Intern on the Efficient AI Team, NVIDIA. My research lies broadly in representation learning, generative AI, and foundation models. Specifically, I want to design simple and efficient learning algorithms and apply them to real-world applications.
I am very fortunate to have had opportunities to collaborate with Prof. Qi Dou, Prof. Alan Yuille, and Prof. Xinggang Wang. I am a recipient of the Viterbi Fellowship.
