David Harari

David Harari is a Professor and Head of the Department of Mathematics at the Institut de Mathématiques d'Orsay, Université Paris-Saclay. His research focuses on algebraic geometry, number theory, cohomology, and arithmetic geometry. He has held significant academic roles, including organizing conferences (e.g., 'Skorobogatov 60') and leading specialized courses in arithmetic and algebraic geometry. He is actively involved in teaching at various levels, from undergraduate to graduate programs, including M1/M2 specialized courses on topics like Brauer groups, algebraic geometry, and Galois cohomology. He also contributes to educational initiatives such as the Algant Master’s program and the Hadamard Doctoral School of Mathematics.

• Teaching Highlights: Courses on algebraic geometry, topology, Fourier analysis, and preparation for the agrégation (French higher education competitive examination).
• Academic Leadership: President of the Mathematics Department at Orsay, organizer of research seminars, and contributor to academic events like the 2019 IHP trimester on rational points.

His research interests span advanced topics including class field theory, étale cohomology, and the Brauer group of fields and schemes. He has authored course materials and exams reflecting these areas, demonstrating expertise in both theoretical and applied mathematical education.
