Introductory Lectures on Higher-Spin Theories

​Stefan Fredenhagen is a theoretical/mathematical physicist and a professor at the University of Vienna (Austria). He completed his undergraduate studies at the University of Hamburg in 1999. As a graduate student, he conducted research at the Max-Planck Institute for Gravitational Physics in Potsdam (Germany) and earned his PhD in 2002 from Humboldt University Berlin (Germany), for which he was awarded the Otto-Hahn Medal in 2003.

Following his doctoral studies, he held postdoctoral positions at the Ecole Polytechnique in Palaiseau (France), the Institut des Hautes Etudes Scientifiques in Bures-sur-Yvette (France), and the Federal Institute of Technology (ETH) Zurich (Switzerland). He served as a junior staff member at the Max-Planck Institute for Gravitational Physics starting in 2006. Subsequently, he held a guest professorship at Humboldt University in Berlin before joining the University of Vienna as a professor of mathematical physics in 2016.

His research focuses on the theoretical and mathematical aspects of quantum field theory, gravity, and string theory, particularly emphasizing higher-spin gravity theories and conformal quantum field theories.

Stefan Fredenhagen 是一位理論/數學物理學家，現任維也納大學（奧地利）教授。他於1999年在漢堡大學完成本科學業。作為研究生，他在德國波茨坦的馬克斯·普朗克重力物理研究所進行研究，並於2002年在德國洪堡大學獲得博士學位，因而於2003年獲得奧托·哈恩獎章。

在博士研究之後，他在法國帕萊索的高等工藝學院、法國比尤爾的高等科學研究所以及瑞士蘇黎世的瑞士聯邦理工學院（ETH）擔任博士後職位。自2006年起，他在馬克斯·普朗克重力物理研究所擔任初級研究員。隨後，他在柏林的洪堡大學擔任客座教授，並於2016年加入維也納大學，擔任數學物理教授。

他的研究專注於量子場論、重力和弦理論的理論和數學方面，特別強調高自旋重力理論和共形量子場論。
