He holds a bachelor's degree in Physics from the Federal University of São Carlos and a master's and doctorate in Sciences from USP, specializing in Astronomy, the latter defended in March 2003. He completed two postdoctoral fellowships (FAPESP) at Unesp/Rio Claro (2005 and 2006). He led the FAPESP Young Researcher project at Unesp/Rio Claro (2007-2010). RDIDP at the Institution since 2009. Full Professor in 2018. He has international experience, having presented papers at conferences in the USA, Germany, Portugal, England, Switzerland, Italy, and Uruguay. He is a member of the International Astronomical Union (IAU) and has the asteroid (30452) Callegari named after him by the IAU. He has scientific experience in Astronomy, Physics, and Applied Mathematics, with an emphasis on Dynamics of Planetary Systems, the Solar System and extrasolar systems, and Differential Equations. His research focuses on resonant dynamics of natural satellites and planetary systems, as well as numerical stability analysis techniques for systems of differential equations. His work focuses on the following areas: i) Astronomy: Dynamics and Evolution of Solar System and extrasolar planets and satellites: mean-motion resonances; rotational dynamics: spin-orbit resonances; and secondary resonances. ii) Applied Mathematics and Mathematical Physics: Differential Equations and applications. Numerical integration of systems of differential equations in classical mechanics and celestial mechanics; numerical Fourier Transform techniques; iii) Physics: Numerical studies of stability and chaos in dynamical systems via dynamical mapping by frequency analysis.

Over the past forty years, space probes and telescopes, as well as large ground-based telescopes, have been responsible for discovering numerous new natural satellites and for providing a wealth of astronomical data with precise observations of the satellites already known, thus revolutionizing the ephemerides of these bodies. It is well known that the current orbital and rotational confi…
The main purpose of this project is to investigate the orbital dynamics of five Saturn's interior satellites discovered in the era of space probes and telescopes: Pan, Atlas, Aegaeon, Methone, Anthe and Pallene. These small bodies have average radii of a few kilometers, and suffer resonant gravitational perturbations from other larger satellites in the Saturn system, such as Prometheus, P…

The recent discovery of several exoplanets with probable terrestrial composition andlocated in unusual orbits very close to their respective stars leads to questions likedynamical stability including the rotational one. The dynamics of rotation has been studied currently by using classical models of rotation around the axis of larger momentof inertia, which is supposed perpendicular to t…
The purpose of this undergraduate research project is to guide the student on topics of celestial mechanics and applications on the problem of rigid body rotation and resonance "spin-orbit". Emphasis will be given on the formulation of the problem and applications to some planets with physical parameters (e.g. radius and mass) consistent with the formation of a terrestrial type (e.g. rock…
The rotation of a non-spherical body (secondary) is disturbed by the torque of the main body (primary). One of the main objectives of the master's thesis of Filipe Batista Ribeiro (proc. 2012/21611-5) is to study the dynamics rotation of a Super-Earth with a conservative spin-orbit resonance model more general than the classical model (Goldreich & Peale 1966). While certain approaches are…
