I am an Associate Professor at Iowa State University. My fields of interest are extremal and probabilistic combinatorics and graph theory.
The MIGHTY LIII graph theory conference is coming to ISU September 28-29, 2012.

A man would make but a sorry chemist if he attended to that department of human knowledge alone.  If your wish is to become really a man of science and not merely a petty experimentalist, I should advise you to apply every branch of natural philosophy, including mathematics.
