个人简历：
张佳，2015年本科毕业于华东理工大学，2021年获美国田纳西大学材料科学与工程博士学位，师从国家千人计划胡斌教授，后赴瑞典林雪平大学青年院士高峰教授团队开展钙钛矿光电子学前沿研究。现就职于复旦大学光电研究院，任青年副研究员。
重点关注高性能新型材料/器件的开发及其机制的理解：首次揭示了钙钛矿表面P型掺杂的发光机制进而打破添加剂缺陷钝化作用的传统认知，获得高效率钙钛矿发光二极管；首次发现界面电荷转移态发光机理进而拓展光电调控维度；首次证实传输层界面可降低激光阈值进而颠覆传输层劣化光增益的固有观念，建立了界面结构在高激发浓度下抑制非辐射复合损失的新机制，为设计低阈值电泵浦激光器提供了关键理论模型；创新性地解决了结晶动力学限制的电荷堆积问题，通过微观结晶调控实现高效双向输运，并在国际上率先实现可直接交流驱动发光二极管；开发了‘上、下界面及晶界’全表界面修饰策略，有效抑制了载流子非辐射复合损失，为突破新型光电子器件的发展瓶颈提供了理论依据。
以一作、通讯作者身份发表高水平论文16篇（包括Nature Materials、Joule（高引）、Nature Communications、Advanced Materials、Advanced Energy Materials、Nano Energy、Nano-Micro Letters 等）。曾多次受邀美国、欧洲材料研究协会及国内学术会议做口头报告。多次担任高影响力学术期刊如ACS Nano等的审稿人。并于2022年获得欧盟玛丽居里学者项目（22.3万欧元，约合175万人民币，主持）；于2023年获得上海市领军人才（海外）项目，于2024年获得上海市科技部国际合作项目（70万人民币，主持），于2024年获海外优秀博士后支持专项（90万人民币，主持）。
