Marco Ripà was born in Rome, Italy, 37 years ago and he still lives there.

He initially studied Physics but he gained a First Class degree in Economics. He speaks Italian, English, French and a little Spanish, while also being able to understand some Portuguese. He is good at mathematics and he likes science very much too. His interests and hobbies include philosophy, Italian poetry (especially Dante Alighieri's verses), literature, chess, powerlifting, fishing and martial arts. He often relaxes by listening to classical compositions, but he prefers rock music and melodic songs. He has a younger sister plus some very good friends. He is an author of number theory papers and the father of about 80 integer sequences listed in OEIS.

He has been voted "Genius of the Year - 2014" representing Europe by the members of the World Genius Directory (GOTY Award).

In November 2014, he released his masterpiece 1729 il numero di Mr. 17-29.

In 2020, Marco Ripà solved the infamous "Nine dots problem" generalized to k-dimensions (see JFMA, Vol. 3(2), pp. 84-97), while in 2021 he released the congruence speed formula for the integer tetration (hyper-4) (published on NNTDM, Vol. 27(4), pp. 43-61).

He is member of more than thirty high IQ societies.

His personal YouTube Channel, focused on mathematics, logic and philosophy, counts about 160k subscribers.

His average score on the first submissions of high range IQ tests (the mean of all the spatial tests and numerical ones he has taken) is close to 200 points on the Cattell Scale (sd=24), while his best performance reaches 211 points on the same scale.

He is the creator of the X-Test, a spoiled difficult logical/numerical test with some divergent thinking (see https://www.researchgate.net/publication/251238254_X-Test_Solutions_Finally_Revealed), and of the ENNDT/ENSDT.

He is currently focused on developing the formula of the number of stable digits of any integer tetration, solving an old problem about Smarandache's circular sequence (see A001292 on the OEIS), and writing a few original research papers about covering paths, circuits, and cycles for two-dimensional grids.
