He presented nucleotide synthesis and metabolism, which isn't the most exciting stuff but he was very thorough and took the time to explain the main points. True he doesn't have powerpoint slides but his notes were provided and had everything important in them. I liked him a lot, really a wisecracker and super laid back for a chemist. People thought he was corny but I found him really entertaining and very knowledgable. His true/false are notorious but just know the material and the main points (which he stresses by raising his eyebrows and talking louder...) and you won't be fooled. I would definitely take him again, he's a really friendly and intelligent guy.
