Ron Aharoni was born in 1952. He grew up on the kibbutzim Kabri and Gesher.

He earned all three of his degrees in mathematics at the Technion. He submitted his master's thesis in 1975 and his doctoral thesis, on combinatorial problems in matrix theory, in 1979. He then did postdoctoral work at Brandeis University and in Reading, England.

His research deals with matchings in graph theory and with hypergraphs. With Nash-Williams and Shelah he extended Hall's marriage theorem to infinite graphs, and he proved versions of the Kőnig and Menger theorems for infinite graphs. In 2000 he proved a topological version of Hall's theorem, which was used to settle open combinatorial conjectures.

In 2000 he began volunteering as a math teacher at an elementary school in Ma'alot-Tarshiha. In 2002 he spoke out against the teaching method then used in Israel and co-founded an association that promoted the Singapore method. In 2010 he joined about 30 mathematics professors in criticizing the middle school geometry curriculum.

He has written several books for general readers, including Arithmetic for Parents and works on mathematics, poetry, philosophy and humor. He won the Ofer Lider Prize in 2011. He is a critic of religion and joined the secular Or party.
