I am an Associate Professor at Iowa State University. My fields of interest are extremal and probabilistic combinatorics and graph theory.
Congratulations to Endre Szemerédi, Abel prize laureate.  Read the tribute by Timothy Gowers.
The MIGHTY LIII graph theory conference is coming to ISU September 21-22, 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.
