Math genealogy

The Mathematics Genealogy Project is an interesting site that keeps a record of people with PhDs in mathematics, statistics, and related fields, as well as who their advisor was, and who their advisor's advisor was, and so on.

Here are the mathematical family trees of some people in the MHC math/stat department I made using the Geneagrapher software:

Note that Andrea's advisor wasn't listed so her tree isn't very detailed at the moment.
