Sascha Orlik

Prof. Dr. Sascha Orlik is a Professor at the University of Wuppertal, leading the Algebra and Number Theory Working Group within the Department of Mathematics. His research focuses on arithmetic geometry, with particular emphasis on p-adic period ranges, the Langlands Program, Deligne-Lusztig varieties, and representation theory of p-adic and finite groups of Lie type. He has contributed to foundational studies in cohomology of period domains and equivariant vector bundles over Drinfeld's spaces.

His working group includes members such as Dr. Andreas Bode, MSc. Erik Barinaga, and MSc. Dominik Briganti, alongside former members like Dr. Martin Bender and Dr. Christoph Spenke. He has authored a notable monograph *Period domains over finite and p-adic fields* (Cambridge Tracts in Mathematics) and numerous influential publications in journals like *Inventiones mathematicae* and *Advances in Mathematics*.

Research trends in his articles span the interplay between geometric and cohomological methods in p-adic settings, with a focus on representation theory and its applications to number theory. His work bridges algebraic geometry, topology, and arithmetic, addressing key problems in modern arithmetic geometry and the Langlands Program.
