Computers and Computation


I have several research projects in computational group theory using the Wildebeest cluster computer located here at CCNY. These projects involve distinguishing members of families of difficult one-relator groups.


I like use the computer algebra system Mathematica (from Wolfram Research). I have written a number of items as part of an effort to use Mathematica in calculus as well as upper division and graduate courses.
