Tim Lee, is an American stand-up comedian and biologist living in southern California. His father gave him the middle name Xtreme, hoping his son would grow up to be a stunt man. Lee rejected that path and focused on the sciences for most of his life, studying ecology and evolution at UC San Diego, where he graduated magna cum laude in biology. He went on to complete his PhD at UC Davis, developing simulation and analytical models of population dynamics before becoming a comedian.
Lee has become popular on YouTube with over 4,5 million views on his videos. His standard method of presentation is performing a "parody of a science seminar" complete with visual aides.
