Bachelor degree in Physics from Universidade Estadual de Campinas (1986), master in Astronomy from University of California at Berkeley (1992) and master in Astronomy from Universidade de São Paulo (1989) and PhD in Astronomy from University of California at Berkeley (1995). Has experience in Astronomy, focusing on solar and stellar activity, acting on the following subjects: solar and stellar flares, spots and atmospheres, extra-solar planets and their interaction with their host stars, planet habitability, and also radio astronomy.

- Solar patrol polarization telescopes at 45 and 90 GHz, AP.R
Abstract
The spectra of solar flares provide important information about the physics involved in the flaring process. Presently, however, there is a large frequency gap at radio frequencies between 20 and 200 GHz. Unfortunately, this gap hinders the determination of important flare parameters such as: (i) the frequency of the peak of the spectra, or turnover frequency, which yields the magnetic ...

- Star-planet magnetic interactions and its consequences for planetary habitability, BP.DR
Abstract
Stars can interact with their close-in planet through their coronal magnetic field. Stellar magnetic field is the driver of activity in the star and can trigger spots, energetic flares, coronal plasma ejections and ionized winds. These phenomena may have an important impact on the atmosphere and magnetosphere of the orbiting planets. As a consequence, they can strongly affect the planet...
- Analysis of solar flare detected by poemas at 45 and 90 GHz, BP.MS
Abstract
Solar activity has a cycle of about 11 years which is related to the appearance of sunspots. Besides spots, other solar phenomena are also related to solar activity such as coronal mass ejections and solar flares. Solar flares produce radiation at various wavelengths, including radio waves of high frequency. The goal of this project is to detect as many solar flares as possible and buil...
- Interaction of extrasolar planets with their host star, BP.IC
Abstract
Currently a total of nearly 300 planets, from more than 800 detected, are known to eclipse their host star. During one of these transits, the planet may occult a spot on the photosphere of the star, causing small variations in its light curve. By detecting the same spot in a later transit, it is possible to estimate the stellar rotation period, similarly to what Galileo did for the Sun ...

- Unveiling haze formation and energy balance in the exoplanets atmospheres with the Hubble Space Telescope, BE.EP.DR
Abstract
We have implemented in the PhD project the study of planetary atmospheres by analysing their composition during a transit. One of the major factors that impact in the evolution of an atmosphere is stellar activity. Therefore, by looking at the atmosphere of a planet, we can have a direct detection of the effects arising from this phenomena. For example, the UV radiation of the star can ...
- Search for Exomoons using timing variations in planetary transits, BE.EP.DR
Abstract
Among the exoplanets detection methods, the planetary transits has been of great importance in the last few years, with a large number of discoveries and important space missions ongoing. More recently, researchers have been studying the possibility of detecting exomoons. The most promising technique for that is planetary transits. Presently, we are developing our PhD program with a sea...
