About me

I was born in Xinxiang, Henan Pronvince. I received Bachelor's degree in School of Computer in June 2018 from Northwestern Polytechnical University (NWPU), Xi'an. In the same year, I was admitted to study for a M.Sc. degree in School of Computer Science and Technology, University of Science and Technology of China without entrance examination. From Sept. 2020, I started my Ph.D. degree under the supervision of Professor Xuehai Zhou and Professor Chao Wang. I received my PhD degree of computer science in December, 2023 at USTC.

娄文启，现为中国科大软件学院特任副研究员，硕士生导师。2018年6月本科毕业于西北工业大学计算机学院， 2023年12月于中国科学技术大学获得计算机系统结构博士学位，导师为 周学海教授与 王超教授。 主要研究方向为智能加速器架构、FPGA加速器设计、软硬件协同优化等，致力于从算法与硬件角度缓解深度学习模型的部署压力。 近年来，在计算机系统结构领域发表学术论文10余篇，包括IEEE TCAD、TC、FPGA、DATE、CODES+ISSS等顶级期刊会议，其中以第一/通讯作者身份发表CFF-A/B及JCR一区论文6篇。

高能效智能计算系统实验室面向中科大计算机学院、软件学院、大数据学院招收推免生与考研生（含软件学院联合培养），如有兴趣欢迎与我联系。
