Presentations
This is a page where I'll put up powerpoint or pdf files from presentations I've given, for your
edification and/or amusement. For the most part they should make sense even without me standing
up in front of you talking, though I like to think the talking part adds something to the
experience. Presentations are listed in reverse chronological order. Note that some of the powerpoint
files will not be formatted correctly unless you happen to have
Igino Marini's Fell Types installed. Also, powerpoint files often have associated notes that may provide
some illumination.
Presentations for Academic Societies
Further adventures in the phylogenetics of
Boechereae (Brassicaceae)

better or worse.
