Dissertation defended!

Last week I presented my dissertation research in a seminar titled "Elevational specialization in tropical montane birds." Following the talk, I completed my B exam and my committee signed off on my dissertation.  Thanks to everyone - friends, family, colleagues at many institutions - who has helped me over these past five years! Here I am writing my initials next to the dent produced in the ceiling tile (just above the "B") from the champagne cork. A Cornell tradition maintained despite room rearrangements that require temporary ceiling tile removal! (The tiles with dents & initials are now located in the departmental office, and had to be brought over to the celebration room...)
