Ceballos Lopez, Cesar

Cesar Ceballos Lopez is an Assistant Professor at the Institute of Geometry, Technische Universität Graz (TU Graz), where he leads the Discrete Geometry and Algebraic Combinatorics Group. He previously held postdoctoral and visitor positions at Freie Universität Berlin, York University, the Fields Institute, and the University of Vienna, where he completed his habilitation in 2020. His academic journey began with a PhD in Discrete Geometry under Günter Ziegler at Freie Universität Berlin (2012).

• Education:
  • PhD in Mathematics, Freie Universität Berlin (2012), Supervisor: Günter Ziegler
  • Habilitation, University of Vienna (2020), TU Graz (2021)
  • Master's in Mathematics, Universidad de los Andes (2008), Universiteit Utrecht (2009)
  • Bachelor's in Mathematics, Universidad del Valle (2006)

His research spans Discrete Geometry, Algebraic Combinatorics, and Representation Theory, with a focus on geometric structures like associahedra, subword complexes, and cluster algebras. His work connects these objects to Hopf algebras, diagonal harmonics, and tropical geometry. Recent publications explore ν-associahedra, s-permutahedra, and combinatorial reciprocity theorems.

Scientific awards include the FWF Stand Alone Project Grant (2021–2025), Banting Postdoctoral Fellowship (2013–2015), and the Elsevier Mathematical Sciences Sponsorship Fund (2018). He organizes seminars such as the Combinatorics Working Seminar at the University of Vienna and contributes to academic communities through conference organization and talks.
