**Senior Researcher III at the National Institute for Space Research (INPE).** Coordinates research projects in Brazil and participates in various international research initiatives. Holds a CNPq Research Productivity Fellowship (Level 2: 20162019; 20222025). **Metrics:** - H-index: 28 (Scopus), 26 (Web of Science Research ID), 33 (Google Scholar). **Roles and Affiliations:** - Scientific advisor for FAPESP. - Reviewer for the NSF (USA), NRF (South Africa), and over 22 scientific journals. - Member of the International Commission on Atmospheric Electricity (19 members). - Member of Cigré (International Council on Large Electric Systems). He has contributed to two working groups composed of 20 researchers from various countries, producing key documents on lightning parameters based on decades of research: - **Working Group C4.407 - Lightning Parameters for Engineering Applications.** - **Working Group C4.36 - Winter Lightning - Parameters and Engineering Consequences for Wind Turbines.** **Research Achievements:** In 2003, he initiated a systematic study of lightning using high-speed cameras. This ongoing research has resulted in the largest collection of high-speed lightning videos globally. These observations have led to significant contributions on atmospheric discharges and their interaction with Lightning Protection Systems (LPS). **Current Research Topics:** - Lightning and its interaction with LPS of towers and wind turbines. - Upward lightning. - High-energy phenomena associated with lightning discharges. **Leadership and Organizational Roles:** - Chair of the Scientific Committee for the 2018 International Lightning Detection Conference/International Lightning Meteorology Conference. - Chair and organizer of the **1st International Workshop on Lightning Physics (WoLPh 2023)** at INPE, Brazil. - Committee Member of the International Symposium on Winter Lightning. - Member of the Space Geophysics Graduate Program at INPE. - Member of the Brazilian Physics Society. **Notable Achievements:** - In 2011, published an article among the **Top 50 most cited** in the past five years in *Atmospheric Research*. - In 2019, 2022, and 2023, four scientific articles were featured on the covers of *Journal of Geophysical Research* (Vol. 124, Issue 12; Vol. 128, Issue 8) and *Geophysical Research Letters* (Vol. 49, Issues 22 and 23). - On March 28, 2023, his research on lightning rod functionality was featured on the cover of *The New York Times*. **Education:** Graduated in Physics from USP, and completed his masters and doctoral degrees at INPE.

Cloud-to-ground lightning are responsible for immense material damage and for more than a hundred deaths annually in our country. The lightning flashes that contain currents of long duration, known as continuing currents, produce damage associated with the heating caused by them (burnings, melting of materials, forest fires, damage to transmission lines, etc.). This project aims at the ob…

Thunderclouds are electrically charged environments that can accelerate particles to relativistic speeds, leading to energetic phenomena such as Terristrial Gamma-ray Flashes (TGFs)-brief bursts of gamma rays with energies in the tens of MeV. One proposed explanation for TGFs is the relativistic electron avalanche feedback mechanism.Our research focuses on identifying the conditions neces…
On September 11, 2021, atmospheric discharges emitting gamma rays were, for the first time, recorded by a high-speed camera and by detectors on the ground simultaneously. The events were detected by the Telescope Array located in the Utah desert (United States of America - USA) and were filmed by the Phantom v2012 camera, set at an acquisition rate of 40,000 frames per second (fps). The p…
The standards that define the requirements for the installation of a Lightning Protection System (LPS) are still based on empirical methods, models and theories that lack data from observations of the actual behavior of LPSs (Bouquegneau, 2007; Becerra 2008). As of 2014, no video had been shot fast enough to understand how lightning rods in buildings react to the approach of lightning. Th…
On January 2012, the first upward lightning in Brazil was recorded. Four upward lightning flashes initiated from one of the towers located on Jaragua Peak, in São Paulo city, three of them were recorded at an interval of six minutes. They were recorded with a high-speed camera (4000 fps) and standard camera. This research project aims to increase knowledge about the upward lightning never…
This research project consists in combining observations obtained through high-speed cameras and atmospheric electric field measurements in order to study two physical phenomena involved in the production of natural cloud-to-ground lightning: M components (pulses that occur during the continuing current and whose peak current value, obtained from triggered lightning experiments, can range…
Upward lightning flash studies are antique (McEachron, 1939). Interest in this subject has grown recently, because of the rapid expansion of wind power generation. Also, with the increasing number of tall buildings and towers, there will be a corresponding increase in the number of upward lightning flashes from these structures. In Brazil, this study started in January 2012, when ELAT Gro…
