Edson Denis Leonel is Professor of Physics at São Paulo State University, Rio Claro, Brazil. He has been dealing with scaling investigation since his Ph D in 2003 where the first scaling investigation in chaotic sea for the Fermi-Ulam model was studied. His research group developed different approaches and formalisms to investigate and characterise the several scaling properties in a diversity types of systems ranging from one-dimensional mappings, passing to ordinary differential equations, cellular automata, in meme propagations and also in the time dependent billiards. There are different types of transition we considered and discussed in these scaling investigations: (I) transition from integrability to non-integrability; (ii) transition from limited to unlimited diffusion and; (iii) production and suppression of Fermi acceleration. The latter approach involves the analytical solution of the diffusion equation. His group and he published more than 150 scientific papers in respectedinternational journals including three papers in Physical Review Letters. He is author of two books in Portuguese language, one dealing with statistical mechanics (2015) and the other one dealing with nonlinear dynamics (2019), both edited by Blucher.
