2013年7月11日，微软亚洲研究院高级研究员、研究经理刘铁岩博士和副研究员王太峰博士应邀访问我校。此次访问得到了“中国科学技术大学研究生教育创新研究计划”的支持，并由研究生院、电子工程与信息科学系、中科院电磁空间信息重点实验室和多媒体计算与通信教育部—微软重点实验室负责承办。

　　上午9点，刘铁岩博士兼职博士生导师聘任仪式在我校西区电三楼314会议室举行。中科院电磁空间信息重点实验室副主任俞能海教授致辞并为刘铁岩博士颁发了兼职博导聘书。俞能海教授对刘铁岩博士的学术成就和与我校在科学研究、人才培养等方面的密切合作给予了高度评价。刘铁岩博士欣然接受聘书并表示，作为科大的兼职博士生导师，以后会经常来科大与师生进行深入交流，进一步加深与我校的学术交流与合作。

　　聘任仪式结束后，刘铁岩博士和王太峰博士为我校师生做了题为“Economics, Security, and Privacy in Web Search”的学术报告。刘铁岩博士和王太峰博士对Web搜索中搜索引擎、广告商和Web用户三方形成的经济链中的相关问题进行了深入细致的讨论和分析。报告重点介绍了Web搜索中点击预测和拍卖机制设计等经济学问题，以及经济链中垃圾邮件、机器查询、点击欺诈和隐私保护等安全问题。在报告中，他们高屋建瓴地阐述了博弈论、机器学习和数据挖掘在研究科学问题中的重要作用。报告会由俞能海教授主持。整个报告会气氛生动活泼，与会师生深感受益。
