He was awarded by WWF in 1998 and was a Tinker Fellow at Stanford University[3] and a visiting professor at Aarhus Universitet, Denmark in 2017.

He is currently one of the Center for Research on Biodiversity Dynamics and Climate Change directors in Rio Claro and Editor-in-Chief of Global Ecology and Conservation.

He grew up in Campinas, São Paulo until the age of 25 when he moved to University of Cambridge to earn the Doctor of Philosophy.

Since his early days in the university, he noticed that most classes were uninteresting to him so he decided to spend most of his mornings in the forest fragment near Mata de Santa Genebra, Campinas, São Paulo.

By following howler monkeys from dusk to dawn, he realized a myriad of frugivoresthat rely on fleshy fruits in the rainforest.

Galetti was supervised by Dr. Leonor Patricia Cerdeira Morellato, who compared the interactions between fruits and frugivores in this forest fragment.

His work is a pioneer in understanding the complex network interactions between fruits and frugivores in hyper-diverse ecosystems.

The small forest fragment near the university was his major laboratory where he spent most mornings watching birds and mammals eating fruits.

In 1988, Galetti attended a talk by the Mexican ecologist Rodolfo Dirzo,[4] who presents for the first time his ideas about the impact of defaunation on plant communities.

At this time Galetti met a young primatologist Carlos A. Peres who influence him to study keystone species instead of primates.

Jordano was a young scientist expert in frugivory and seed dispersal who took Galetti to Sierra de Cazorla and taught him about the Mediterranean ecosystems.

After four months in Borneo, he moved back to Brazil and became a professor at São Paulo State University in 1998 where he works at the Department of Biodiversity.

He was a visiting scientist at Spanish National Research Council in Seville in 2007 and Thinker Professor at Stanford University from 2008 to 2009 at Center for Latin American Studies.

Galetti was the pioneer in publishing about rewilding,[8] particularly after visiting Kruger National Park in South Africa.

Galetti has written on ecology for several journals including Science, PLOS ONE and Biological Conservation [9] and his contribution has been much debated by public media.
