Sergey Lysenko is a Professor at the University of Lorraine , affiliated with the Institut Élie Cartan de Lorraine (IECL) and the GDR Algebraic and Geometric Lie Theory . His research centers on the geometric Langlands program and its connections to representation theory. Research Interests: Geometric Langlands program, automorphic sheaves, metaplectic groups, theta-lifting, geometric aspects of representation theory, and Satake equivalence. Students: Supervised three PhD students: Banafsheh Farang Hariri (2012), Lizao Ye (2019), and Ruotao Yang (2020), with ongoing collaborations in geometric representation theory. Publications: Over 30 works focusing on geometric Langlands, quantum groups, and automorphic periods, including key contributions to metaplectic Whittaker categories and theta-lifting. Grants: Coordinator of the ANR VARGEN project (Varieties of characters and generalizations) from 2013–2018. Teaching: Taught courses in algebra, topology, and bilinear algebra at University of Lorraine. Scientific Leadership: Active in seminars and workshops on geometric Langlands, including the Nancy–Paris 2010 seminar. Member of the geometry team at IECL and GDR Algebraic and Geometric Lie Theory .
