Piotr A. Woźniak ([pjɔtr ˈvɔʑɲak]; born 1962) is a Polish researcher best known for his work on SuperMemo, a learning system based on spaced repetition.
Woźniak was born in March 1962 in Milanówek, Poland.
He began to develop his spaced-repetition software after struggling to retain course material as a student at the Poznań University of Technology in the 1980s.
He received a doctorate from the Wrocław University of Economics in 1995. His doctoral dissertation was entitled Economics of Learning: New Aspects in Designing Modern Computer Aided Self-Instruction Systems.
In addition to the theory of spaced repetition, his research interests include incremental reading and the optimization of sleep.
He supports the idea of a single international auxiliary language, and for two years kept a diary in Esperanto.
