劳伦斯·德·哈恩（Laurens Theobald de Haan）教授于2014年在荷兰埃因霍温理工大学获得博士学位，师从液晶聚合物材料领域知名学者Dirk J. Broer教授与A.P.H.J. Schenning教授，研究方向为“液晶高分子网络的可编程形变”。博士毕业后加入华南师范大学周国富教授团队，并与深圳市国华光电科技有限公司合作开展博士后研究工作。2019年入选国家级人才项目并受聘为华南师范大学教授。

德哈恩教授课题组目前主要致力于开发基于液晶聚合物的响应型光子表面材料，已成功研制出能对温度、湿度、应力及pH变化产生光学响应的智能表面材料，并展示了其作为传感器件和控温智能窗的潜在应用。在当下和今后的研究中，课题组将着力于提升该类光子材料的响应性能，推进其在特定生物分子检测、污染物监测等精准检测场景的转化应用。德哈恩教授与荷兰和比利时多所高校保持着密切的科研与学术合作。

导师是外国人似乎颇具挑战，但其实并不难。在实践中，学生们将很快掌握如何用英语与导师沟通。在跨文化科研环境中，团队成员不仅能系统提升专业英语能力，还可通过联合培养机制获得赴欧洲学术交流的机会。实践表明，这种国际化培养模式可有效促进科研创新与人才成长。

Prof. Laurens Theobald de Haan received his PhD degree in 2014 from the Eindhoven University of Technology on “Programmed Morphing of Liquid Crystal Polymer Networks”. His PhD supervisors were prof. D.J. Broer and prof. A.P.H.J. Schenning, who are both renowned professors in the field of liquid crystal polymer materials. After obtaining his PhD degree he accepted a postdoctoral position at South China Normal University (SCNU) in Guangzhou in collaboration with Guohua Optoelectronics in Shenzhen, under supervision of prof. G. Zhou. In 2019 he was awarded a national talents program and obtained his current position as a full professor at SCNU.

His current projects mainly focus on the development of responsive photonic surfaces based on liquid crystal polymers. He and his students have prepared photonic surfaces that their reflective properties in response to heat, water, strain, and pH changes, and potential applications as sensors and in temperature-regulating smart windows have been demonstrated. In current and future projects, the responsiveness of the photonic polymers is further improved to expand the scope of these materials, for example to detect specific biomolecules or pollutants. Prof. Laurens de Haan has collaborations with professors at universities in the Netherlands and Belgium.

Having a foreign professor as a supervisor might sound like a challenge, but in reality it is not all that difficult. In practice, students quickly learn how to communicate in with their supervisor in English. Being guided by a foreign supervisor has several benefits, including improved language capabilities and the possibility of foreign exchange.
