Jetzt, das Ende.
My NC State career (1978-2025) is fading away.
I will leave my office at 3234 SAS Hall no later than June 30, 2025.

It's been a pleasure doing business with you. Thank you very much.

In the past I worked on multilevel methods for integral equations, quasi-Newton methods, semiconductor modeling, optimal control, optimization of noisy functions, flow in porous media, and computational quantum chemistry and physics.

I distribute MATLAB software for Linear Equations, Nonlinear Equations, and Optimization . I have new Julia software for Nonlinear equations.

• I am officially retired, collecting a pension, Social Security, and Medicare.
• My title is (and I am not making this up) Named Professor Emeritus
• I am now on a part-time (<< 10% FTE) NCSU appointment through 9/30/25 to wrap up my part of
  the DOE funded CEMeNT project.
• My post-retirement projects are
  • one more book,
  • the SIAM Advancement Advisory Committee , Financial Management Committee , and Book Committee
• Students, read this!
  • If you want to put me on your PhD committee, I will do it if and only if
    • you are part of the CEMeNT project,
    • expect to finish no later than 12/31/2025, and
    • I live that long.
  • No exceptions.

  New stuff

  My new book: Solving Nonlinear Equations with Iterative Methods: Solvers and Examples in Julia published in print on Oct 31, 2022, just in time for holiday giving.
  Check out the Julia package and the Notebook .
  

  Lea Jenkins (PhD 2000) is the new SIAM VP for Education. Yet another former student becomes a big shot.
  

  SIAM has noticed that I have a new job

  Old new stuff

  My last PhD student Zack Morrow left the building on July 9, 2021. He is now at Sandia.
  

  Katie is now the Robert A. Plane Endowed Chair at Clarkson University
  

  My term as SIAM board chair expired in Dec 2019. Praise to the term limit gods!
  

  They made me a fellow of the AAAS .
  

  Why publish with SIAM?

  The Mathematics Department at Purdue gave me the outstanding Alumnus Award for 2013.
  

  I'm somebody now! Scroll to the bottom of Henk van der Vorst's
  math portrait page.
  

  Why should you join SIAM ?
  

  A REALLY OLD picture.
