Brief Biography

I am a Senior Applied Scientist at Amazon, where I work on research and development of large-scale AI systems, with a focus on foundation models, large language models, reinforcement learning, and information retrieval. My work spans fundamental research and practical applications, including code generation and optimization, generative retrieval and recommendation, efficient LLM training and inference, and multimodal understanding.

Prior to joining Amazon, I was a postdoctoral researcher at ETH Zurich, working with Prof. Ce Zhang. I received my Ph.D. in Computer Science and Engineering from the University of New South Wales (UNSW Sydney), advised by Prof. Lina Yao, and supported by the CSIRO Data61 PhD Scholarship. I obtained my Bachelor’s degree from Nanjing University.

My work has been recognized with several awards, including the Outstanding Paper Award at ICLR 2021, and a Best Paper Award runner-up at WSDM 2020, an Area Chair Award at ACL 2024, the Best of the Best Paper Award at the Global Marketing Conference (GMC) 2023.
