Jonathan A Poritz

What I do:

• Three roles at Colorado State University Pueblo, in Pueblo, Colorado, USA:
  • In Spring of 2021, I'm teaching CIS 491: Special Topics, Introduction to Cryptology, for which see
    • The CIS 491 syllabus
    • The CIS 491 schedule and assignments
  • OER Coordinator, attached to the CSU-Pueblo Library
  • Associate Professor in the Department of Mathematics and Physics
• Another role, through the Colorado Department of Higher Education:
  • member of the Colorado OER Council [having been chair in 2018-19]
• Blogging as μαθηματικoς (at mathematikoi.net) and tweet as @poritzj.
• I use pronouns he/him.

What I've done:

• Lots of teaching info in these web pages for many past courses I have taught.
• Always SHARE: here is material I'm putting out in the world, such as articles, books, slide decks (and sometimes video or audio) from talks, etc. — I think of this as my own little contribution to the global intellectual commons.
• Great detail is in my up-to-date CV.
• A mathematical project I did long ago resulted in a gallery of some fundamental domains in the interior of $H^3_\RR$ for the action of cyclic subgroups of $PSL(2,\CC)$.
• Some of my activities are memorialized on this page with my "badges".

Where I am:

• Here is my physical space contact information. [And if you need to recognize me in person, see this serious, professional image of me or else a more fun image of me with flowers in my hair.]
• E-mail: jonathan@poritz.net (That is my primary, preferred e-mail address. You can also try jonathan.poritz@csupueblo.edu, poritzj@post.harvard.edu, or jonathan.poritz@gmail.com if you like)
  An old public key of mine (fingerprint 7C8B ADBA FE03 3C31 4E52 071D 8488 65F3 7638 565E) was compromised: please no longer use it. I do speak crypto, so if you want to send me encrypted mail, I can set it up.
