Professor Adam Crowley has a course on Zombies in literature on youtube. LINK
no, I haven't listened to them (I am not into Zombies) but his previous talks on Sci Fi have been pretty good.
unrelated item: The Scottish Antiquities society now has their Rhind lectures on youtube, which is a big help since in the past I had to watch them streaming at their website.
Some are good, and some are too technical, but if you are into Scottish antiquity/myth you might want to check them out.
