My research interests are in linear/nonlinear equations, radiative transfer problems, multilevel methods for integral equations, optimal control, optimization of noisy functions, flow in porous media, and computational quantum chemistry and physics. I am a proud member of the NCSU Numerical Analysis Group.

I distribute MATLAB software for Linear Equations, Nonlinear Equations, and Optimization . Our group supports MATLAB codes for optimization of noisy functions.

I am developing a Julia package and a Jupyter Notebook for nonlinear equations.

• I am officially retired, collecting a pension and medicare.
• My title is (and I am not making this up) Named Professor Emeritus
• I have a half-time appointment ending 6/30/24 working on
  • Three grants: DOE(1), NSF(2)
  • Two books
  • The SIAM Financial Management Committee and Book Committee
• Students, read this! I will be on the road a lot. So ...
  • If I am on your PhD committee, I will continue to do my job. I may be harder to schedule, but not impossible. I will attend your exams at 4am from Hong Kong if I must.
  • If you want me to be on your PhD committee, I will do it if and only if
    • I am collaborating with you on research or
    • you are part of the CEMeNT project.

New book: Solving Nonlinear Equations with Iterative Methods: Solvers and Examples in Julia. Under contract with SIAM. Check out the Julia package and the Notebook .

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!

Yet another academic grandchild via Katie. Joshua Beauregard finished on April 3.

They made me a fellow of the AAAS .

Katie did it again! Jesse Clark-Stone was my latest academic grandchild until (see above)

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.
