I TA'd for Tim Gentner at UCSD. He tried to recruit me to his lab; interesting research but I really hated corralling birds. Each quarter a different grad student is responsible for 'the pigeon lab'. It's 10% showing undergrads how reinforcement learning works, 90% chasing down loose pigeons through the basement of McGill & Mandler Hall. I could barely get the pigeons, so I was always in aw of how his lab members gently snatched finches in mid flight.
