孙国梓，博士，教授，博士生导师，南京邮电大学数据安全合规应用技术研究所所长，江苏省科学技术协会江苏省首席科技传播专家（网络空间安全），中国计算机学会杰出会员，中国电子学会高级会员，江苏省计算机学会区块链专业委员会秘书长、南京区块链产业应用协会会长，中国计算机学会区块链专业委员会执行委员，中国电子学会电子数据取证专业委员会委员，声像资料、电子数据鉴定司法鉴定人。

主要研究方向为：数据安全与隐私保护、电子数据取证、区块链存证、人工智能等。

1) 数据安全与隐私保护：基于传统网络安全的研究基础，结合区块链、现代密码学及细粒度访问控制等技术，对数据安全相关问题进行深入研究；当前《网络安全法》、《数据安全法》、《个人信息保护法》等法律已正式实施，结合人工智能、联邦学习、隐私计算等相关技术对隐私保护及数据合规使用问题进行深入研究。

2) 电子数据取证：结合人工智能、数据挖掘等相关技术对网络传播的文字、音频、视频等内容进行溯源取证。主要研究计算机电子数据取证过程中所涉及的电子证据的可采用性问题、电子证据获取、保全、分析以及鉴定，电子证据的有效性证明、取证与反取证、取证的工作标准和规范、取证工具等。

参与国家"973"计划、"863"计划、十五科技攻关计划、十一五科技支撑计划各1项，负责并参与国家自然科学基金项目4项，负责国重实验室项目3项，负责江苏省青年科技基金、校人才启动项目各1项，横向项目20余项。在计算机学报、通信学报、TSE、TSC、TKDD、TNSE、JSS、KBS、ESWA、JSA、AIR、SCN、MTA、FGCS、WWW、ICASSP、ICC、GLOBECOM等国内外期刊、会议发表学术论文100余篇，其中，SCI检索论文37篇，EI检索论文80篇，合作编写2部数字取证方向的专著，翻译专著《网络入侵调查：网络工程师电子数据取证方法》及《区块链安全实战》。获得授权专利30余项。

目前在研国家自然科学基金面上项目一项，企业横向合作项目多项。
