The best way to reach me or to make an appointment is to write an email.
If you write to me I promise I will reply as soon as I can.

I was be on sabbatical 2022-23 and medical leave. A more detailed calendar will be available later.

Talks, Conferences, Workshops, and Seminars:

• I have been actively involved in many mathematical events (as speaker, organizer, as participant). They ranged From some long
  and large (e.g., the semester on Discrete and Computational Geometry at the Mathematical Science
  ResearchInstitute (MSRI) in Berkeley Fall of 2003), to some smaller shorter regonal events (e.g., several SIAM,
  MAA, and AMS meetings). I have also organized conferences at many institutes around the world: AIM, BIRS-Banff, IPAM, IMA, ICERM, Oberwolfach, Hausdorff Institute, etc).

  Here are some events Events in which I am actively involved, either as organizer or scientific committee or participant:

  • DANGER Workshop (Data, numbers, and geometry), focused on research at the intersection of pure maths and data science. 25-26, August, 2022 (online).
  • Workshop "Polytope Diameter and Related Topics" via Zoom on September 2 (based on European Timezone), 2022 (online)
  • Institut Henri Poincare Paris Thematic Program in the "Geometry and Statistics in Data Sciences". From September 5th to December 9th, 2022.
  • Centre for Topological Data Analysis based in Oxford, Liverpool, and Durham, Applied Topology seminar. virtually on Friday December 2, 2022, 15:00 UK time.
  • Symposium of Discrete Mathematics and Richard-Rado Prize From 30th September to 1st October 2022, in person at Hamburg University of Technology (TUHH).
  • Joint Mathematics Meetings Boston, January 2023
  • ICERM ``Discrete Optimization'' semester program (January to May 2023).
  • Univ. of Colorado Denver, May 15, 2023. Workshop is "Circuit Diameters and Augmentation: Recent Advances in Linear Programming".
  • I regularly attend, I have organized, and help found our Algebra and Discrete Mathematics Seminar and the Mathematics of Data and Decisions.
    I helped to launch, and continues to support,
    the Bay Area Discrete Math Day , (widely known for its great mathematical lectures and its curious acronym).
