I received my Ph.D. from the University of Pennsylvania in 1998 and I have been teaching since then at SUNY Oneonta for 1 year, at Shepherd University for 5 years, at Tennessee Tech for 2 years, at Lane College for 1 year, and this year I taught at the University of Massachusetts Lowell. My research interests include Representation Theory and Combinatorics.

## LinearAlgebra:-Modular:-Random...

Try to generate a random matrix modulo m using, say, examples from the ?LinearAlgebra,Modular,Random help page.

## A bug in residue...

Studying the integral bug discussed in Axel Vogt's blog, I met the following,

```residue(arctan(z)^2/(1+z^2),z=I);

1/2      1/2 2
2    (z I)
1/2 I ln(-------------)
2
```

Not talking whether the residue has sense in this case, or not, having z in the answer is very wrong.
