My name is Elisson Saldanha da Gama de Almeida. I am a Brazilian astronomer born on February 18, 1991, specializing in spectroscopy, long-baseline interferometry, and radiative transfer modeling of massive hot stars. I study line-driven winds and circumstellar disks, combining CMFGEN and HDUST modeling with high-angular-resolution and high-spectral-resolution observations.

I am currently a research fellow under CNPq/MCTI/FNDCT Call No. 21/2024 – “Programa Conhecimento Brasil – Atração e Fixação de Talentos” (Line 1) at the Observatório Nacional-MCTI (Rio de Janeiro, Brazil), where I am working on the project A Spectroscopic and Interferometric Study of the Circumstellar Environments of Hot and Massive Stars through Hydrodynamic and Radiative Transfer Simulations.

At the Observatório Nacional-MCTI, I work within the Massive Stars group led by Dr. Marcelo Borges Fernandes. I also take part in the OCEANS international collaboration (Overcoming Challenges in the Evolution And Nature of Massive Stars), funded by the European Union’s Marie Skłodowska-Curie Actions. The project is led by Dr. Michaela Kraus (Astronomical Institute of the Czech Academy of Sciences, Czech Republic), and Dr. Marcelo Borges Fernandes serves as the local PI in Brazil.
