XinyuMa (马新宇)
I am now a Senior R&D Engineer at Baidu Search. Before that, I received the Ph.D. degree in Computer Science at Institute of Computing Technology, Chinese Academy of Sciences, advised by Prof. Jiafeng Guo in 2023. And I received the B.E. degree from Shandong university in 2017. I have broad research interests in information retrieval and natural language processing, especially in the pre-trained models (including Large Language Models) for Search.
