个人介绍
李乾博士具体研究方向包括算法设计与分析，计算复杂性，量子电路优化等。于2013年在重庆大学获得集成电路设计与集成系统专业的学士学位。2018年在中国科学院计算技术研究所获得博士学位，师从孙晓明研究员，期间曾赴加州大学圣迭戈分校访问Shachar Lovett教授。2018年入职阿里巴巴任高级算法工程师，负责搜索广告的拍卖机制设计，期间为阿里巴巴设计了一套广告位拍卖机制，其每年可以为阿里巴巴集团多创造上千亿人民币的成交额以及约十亿人民币的利润。随后入职深圳计算科学研究院，跟随英国皇家科学院院士、中国科学院外籍院士樊文飞从事大数据理论方向的研究工作，期间其共同撰写的关于量子洛瓦兹局部引理的论文被理论计算机顶级会议—STOC录用。据不完全统计，这是华南地区单位首次被该会议录用论文。担任CCF理论计算机专委会执行委员。其工作发表在STOC, SODA , Theory of Computing, ACM TOCT等理论计算机科学会议/期刊上。
