My Ph.D. dissertation focused on methods of teaching grammar to ESL students. Part of my research was concerned with how people understand idiomatic phrasal verbs such as count on or put up with. I have also done research on metaphors, especially political metaphors such as the candidates are going down to the wire, battleground states, or a bull market. I have written a book cataloging more than 2000 metaphors in 54 categories. I have a blog at www.politicalmetaphors.com discussing how these metaphors are used in everyday political discussions.
