Piotr A. Woźniak (pronounced as /pl/; 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.
He prefers anonymity as it allows him to focus on his learning without distraction.
In addition to the theory of spaced repetition, Woźniak's research interests include incremental reading and the optimization of sleep.
He has written extensively about the failure of schooling, believing that learning needs to be driven by the natural "learn drive".
He supports the idea of a single international auxiliary language, and for two years kept a diary in Esperanto.
