Láysa Cristina Araújo Resende Chagas

Láysa Cristina Araujo Resende Chagas is a highly accomplished expert in Space Geophysics with an impressive academic and professional career. Her work centers on Space and Atmospheric Sciences, specifically focusing on the ionosphere during space weather events. As a Post-Doctoral Researcher at the China-Brazil Joint Laboratory for Space Weather (CBJLSW), she is deeply involved in the development of Space Weather forecast indices to support sectors like civil aviation and technology companies.Dr. Laysa's research primarily addresses the ionospheric E-region, with an emphasis on Sporadic Layers (Es), particularly in equatorial and low-latitude regions. These layers play a crucial role in ionospheric dynamics, influencing various phenomena such as equatorial electrojet irregularities, Kelvin-Helmholtz instability, and particle precipitation. Her work also investigates the coupling between the E and F regions of the ionosphere, with a focus on how these interactions are affected during space weather events. A key feature of her research is studying atypical auroral Es layers observed in Brazil, often linked to the South American Magnetic Anomaly (SAMA).Additionally, she has contributed significantly to the field by applying advanced methods like digital ionosonde data and radio occultation techniques (gained during her postdoctoral fellowship in Germany at GeoForschungsZentrum Potsdam), to model and analyze ionospheric phenomena. She has also been a key figure in developing the new ionospheric manual for URSI, aimed at monitoring and reducing Es layer disturbances in Brazil.Her leadership role as the president of the Brazilian Society of Space Geophysics and Aeronomy (SBGEA), along with her membership in the International Space Weather Action Teams (ISWAT), further highlights her prominence in the global space weather research community. With over 70 published scientific articles, Dr. Laysa has earned numerous scientific awards, both as a first author and co-author.Her work not only advances scientific understanding of ionospheric processes but also has practical applications for improving space weather forecasting and its impact on technologies like GPS, communications, and aviation.
