Stephen LaBerge (born 1947) is an American psychophysiologist specializing in the scientific study of lucid dreaming. In 1967 he received his bachelor's degree in mathematics. He began researching lucid dreaming for his Ph.D. in psychophysiology at Stanford University, which he received in 1980. He developed techniques to enable himself and other researchers to enter a lucid dream state at will, most notably the MILD technique (mnemonic induction of lucid dreams), which was used in many forms of dream experimentation. In 1987, he founded The Lucidity Institute, an organization that promotes research into lucid dreaming, as well as running courses for the general public on how to achieve a lucid dream.In the early 1980s, news of LaBerge's research using the technique of signalling to a collaborator monitoring his EEG with agreed-upon eye movements during REM helped to popularise lucid dreaming in the American media.
