Editor-in-Chief of Maple Transactions. Emeritus professor at Western University in London, Ontario. Still connected to Computer Science there, and also to Computer Science at the Cheriton School in Waterloo. My main interests these days are Bohemian Matrices, but I am currently writing a book on perturbation methods, to be published by SIAM. Recent publications include another SIAM book, ``Computational Discovery on Jupyter’’ (mostly Python, I am afraid, with some Maple) which might be of interest to some of the people here. Numerical analyst and computer algebraist by training. Just learning Julia now, but I like what I see.
