Celebrating Charlie Van Loan

Charlie Van Loan, Joseph C. Ford Professor of Engineering in the Department of Computer Science at Cornell University, retires in summer 2016.

Charles Van Loan. The Entertainer. By Henk van der Vorst (linocut 2010)

Charlie has been a huge inspiration to me and many others, not least through his book Matrix Computations, with Gene Golub, now in its fourth edition. I wrote about the book on the occasion of the publication of the fourth edition (2013) in this previous post.

Following his PhD at the University of Michigan, Charlie visited the Department of Mathematics at the University of Manchester in 1974–1975 as a Science Research Council Research Fellow. He wrote the department’s first Numerical Analysis Report as well as three more of the first ten reports, as explained in this post.

A 55-minute video interview with Charlie by his colleague Kavita Bala, recorded in 2015, is available at the Cornell University eCommons. In it, Charlie talks about his PhD, with Cleve Moler as advisor, life as a young Cornell faculty member, the “GVL” book, computer science education, and many other things.

A two-part minisymposium is being held in Charlie’s honor at the SIAM Annual Meeting in Boston, July 11-14, 2016, organized by David Bindel (Cornell University) and Ilse Ipsen (North Carolina State University). I will be speaking in the second part about Charlie’s work on the matrix exponential. The details are below. If you will be at the meeting come and join us. I hope to provides links to the slides after the event.

    I’ve added a link to my talk. Coleman’s talk was cancelled, so David Bindel, Ilse Ipse and Cleve Moler used the slot to offer more personal comments about Charlie.
