个人简历：
王彦晶，男，1982年3月北京生人。2004年本科毕业于北京大学哲学系逻辑学专业，2006年获得荷兰阿姆斯特丹大学逻辑硕士学位（Cum Laude），2010年获得阿姆斯特丹大学逻辑学博士学位（博士研究在荷兰数学与计算机研究所CWI完成）。现任北京大学哲学系长聘副教授/研究员，副系主任，中国逻辑学会现代逻辑专业委员会秘书长, 中国数学学会数理逻辑专业委员会委员。入选国家“****”之青年拔尖人才支持计划。
研究方向：1 模态逻辑，特别是基于非经典语义的知识逻辑（epistemic logic）与动态逻辑（dynamic logic），以及它们的杂交变种后代。2 其他好玩的和逻辑沾点边儿的问题。
已开设课程：《高级模态逻辑》、《动态逻辑》、《知识逻辑》、《哲学数学计算机中的逻辑》等。

希望自己能做到：Kp → KKp（知之为知之），~Kp → K~Kp（不知为不知），K?xPx → ?xKPx（知其然亦知其所以然）
长期的工作目标：反思与应用推动学科发展，真诚与务实促进制度创新

一些正在做的工作的基本想法：
1 超越“知道如是”的知识逻辑：传统的知识逻辑主要关心“知道如是”（knowing that），而我们将“知道是否”、“知道是什么”、“知道如何”、“知道为何”等作为模态算子构造新的模态语言，参考哲学及语言学的讨论给出直观的语义，得到的新的一大类模态逻辑，它们通常是一阶或二阶模态逻辑的可判定片段，但是能避免很多量化模态逻辑的技术及哲学困难，具有良好的逻辑及计算性质，可以加深我们对于这些不同种类的知识的理解，并且引出一些新的逻辑技术，启发我们找到了一系列一阶模态逻辑的可判定片段，与诸多已知的逻辑有令人意想不到的关联，通过形式化的工作，对于相关的哲学问题也有一些新想法。欢迎加入我们，共同推进这个新领域！
2 基于不确定性的规划的逻辑方法：将时态知识逻辑与动态知识逻辑进行重组整合，取长补短，在模型中包括有穷表示的时态信息，而不确定性的更新通过类似动态知识逻辑的方式实现，从而得到了一系列具有良好计算性质的新逻辑，可以用来处理具有不确定性前提的自动规划问题。相比传统的AI方法，我们的逻辑方法不需要在复杂性上付出代价，但是用更直观的方式处理更加丰富的问题。
3 动态知识逻辑的公理化：传统方法依赖于所谓“归约公理”，很多证明系统忽视了归约公理之外的重要规则，对它们的完全性造成了影响。其实“规约公理”只是一个“美丽的巧合”，不用它们照样可以做动态知识逻辑的公理化，我们提出取道时态知识逻辑的一般办法，可以系统性地解决很多动态知识逻辑的公理化问题，同时也拓展了动态知识逻辑的范围，并且能对动态知识逻辑的本质有更深刻的认识。
4 非完美信息博弈模型的构建：博弈论中对非完美信息博弈的信息集有不同解释，有时会带来奇怪的现象，我们试图把博弈规则和参与者的假设分开，通过构造的方式计算博弈过程的信息集，避免模糊和矛盾的产生。
5 基于协议的知识逻辑：动作的意义来源于之前的协议约定（如 举火为号），我们基于协议的知识给出一种新的动态知识逻辑，这里符号的意义可以根据协议改变。
