Hello, a bit about me:

I recently completed my fifth year and will be on the academic job market in Fall 2026. I am working under the supervision of Dr. Peter Patzt . I received my B.S. in Mathematics from the Lebanese University and my M.S. from the American University of Beirut.

Research Interests

  • Group Cohomology
  • Congruence subgroups of arithmetic groups
  • Steinberg module
  • Homological Stability

Research Papers

  • Codimensions one and two cohomology of Hecke congruence subgroups, with Jeremy Miller arXiv: 2606.23519
  • Top-dimensional rational cohomology of the congruence subgroup Γ0,n(p) arXiv: 2605.23526

Outreach Highlights

Notes

  • As part of the Configuration Spaces Summer School, I wrote expository notes on homological stability for unordered configuration spaces using the Arnol'd–Segal filtration, which are available here.
