Welcome to Lemao’s Homepage

I am currently a principal researcher at Tencent, working on large language models, natural language processing, machine translation and their related topics. I can be reached through NAME at gmail dot com (NAME=lemaoliu).

More about me

I am from Yugan in Jiangxi Provice, which is a small yet beautiful county near Poyang Lake, the largest freshwater lake in China. I earned my Ph.D. degree at Harbin Institute of Technology (HIT) in Oct. 2013, under the instructions of Prof. Tiejun Zhao at HIT and Dr. Taro Watanabe at NICT. After that, I was a postdoc researcher at the City University of New York, working with Prof. Liang Huang; and then I was a researcher at NICT Japan between Sept. 2014 and March 2017.
