个人情况简介:
佘志坤,男,1977年出生。北京航空航天大学数学与系统科学学院教授、博士生导师。2007年度北京市优秀人才,2007年度北京航空航天大学蓝天新秀,2008年度北京市科技新星,2013年度教育部新世纪优秀人才,2014年度国家优秀青年科学基金项目获得者。获2013年度教育部自然科学奖一等奖(第三完成人)。1995年9月到2005年6月,就读于北京大学数学科学学院,获理学学士和博士学位(硕博连读);2004年1月到2006年12月,工作于德国马普计算机科学研究所。
他主要在混成系统自动验证、微分方程和动力系统、符号-数值计算、计算复杂性、空间非开普勒轨道分析与优化控制等领域从事基础和应用研究。博士期间,在导师郑志明教授的指导下,提出了伪除机理论,从而推广了Smale等提出的著名的BSS机器(即所谓的实图灵机模型),并在2002年国际数学家大会分会场做此研究成果的报告。以此为基础,在实代数系统的研究上也取得了一系列原创成果。Herbrand奖得主、德国马普计算机科学研究所前所长H.Ganzinger教授高度重视,特意邀请他前往德国马普计算机科学研究所做短期访问;随后,在未取得博士学位情况下,他被破格邀请到马普从事博士后研究,并进入德国大型跨区域科研项目AVACS(www.avacs.org)的核心研究小组之中。
在混成系统自动验证领域,他对非线性混成系统安全性自动验证问题进行了直接处理,突破了之前理论主要通过线性近似来讨论的局限性,并开发了自动验证软件Hsolver(hsolver.sourceforge.net/)。由美国工程院院士Alberto L. Sangiovanni-Vincentelli发表的、详细介绍国际上混成系统研究方面最新进展的综述性学术论文《Languages and Tools for Hybrid Systems Design》(Foundations and Trends in Electronic Design Automation. Vol. 1, No 1/2 (2006), 1-193)在134至140页介绍的就是其工作,其评价是“HSolver improves the traditional method by implementing a pruning algorithm that removes uninteresting parts of the state space before reducing the grid size. Consequently, the refinement of the over-approximation can be obtained even without increasing the number of grid locations, one of the causes of exponential blowout in the verification algorithms for hybrid systems”、“The language for describing hybrid systems is very easy to understand. There are no limitations in describing a single automaton and the limited number of statements in the language makes it simple to use”。
归国后,他把混杂(成)系统引入到空间非开普勒轨道的分析与优化控制之中,被誉为“从混杂系统研究空间轨道构思新颖,是航天器轨道研究的一个新方向”。 发表在《宇航学报》的学术论文《空间非开普勒轨道分析与控制中的数学问题》被西北工业大学精品课程《航天器飞行力学》列为学科前沿(http://jpkc.nwpu.edu.cn/jp2011/04/xuekeqianyan.html)。
他独立撰写国防报告3部,在ACM Transactions on Embedded Computing Systems、SIAM Journal on Control and Optimization、Journal of Symbolic Computation、Celestial Mechanics and Dynamical Astronomy等领域国际顶级刊物和AAAI、CAV、ISSAC、HSCC等领域国际顶级会议上发表学术论文40余篇。研究成果被来自于Massachusetts Institute of Technology、Stanford University、University of California at Berkeley、University of Cambridge、University of Oxford、ETH Zurich、Carnegie Mellon University、RWTH Aachen、日本早稻田大学、新加坡国立大学、清华大学、CNRS、INRIA、MPII、中国科学院软件所等国内外著名机构的学者他引300余次,单篇最高他引90余次。特别地,图灵奖得主Edmund M. Clarke、美国工程院院士Alberto L. Sangiovanni-Vincentelli、美国工程院院士、欧洲科学院院士Moshe Y. Vardi、欧洲科学院院士Marta Kwiatkowska、清华大学孙家广院士、斯坦福大学Prof. Zohre Manna、ACM会士、IEEE会士Prof. John A. Stankovic、ACM会士Prof. Lawrence Paulson、IEEE会士Prof. Bruce Krogh、IEEE会士Prof. Bud Mishra、IEEE会士Prof. Insup Lee、IEEE会士Prof. John Lygeros、IEEE会士Prof. George Pappas等给予了积极的正面评价,诸如“明显优势”、“极大改进”、“灵感之源”等等。
