Tiago Pereira

Tiago Pereira is an Associate Professor at the University of Oslo's Institute of Theoretical Astrophysics, affiliated with the Rosseland Centre for Solar Physics. His research focuses on computational astrophysics, radiative transfer, and solar atmosphere dynamics. He holds a PhD in Astronomy and Astrophysics from the Australian National University (2010) and has conducted postdoctoral research at institutions including NASA ARC and Lockheed Martin ATC (2010-2012). His work leverages high-performance computing to model solar phenomena such as spicules, chromospheric heating, and transition region dynamics.

His research emphasizes radiative transfer in 3D MHD simulations, with particular attention to NLTE effects and the interplay between chromospheric layers. Key projects include the development of SunnyNet—a neural network approach to radiative transfer—and analysis of data from missions like IRIS and Hinode. Recent work explores spicule dynamics, Kelvin-Helmholtz instabilities in solar plasma, and the role of unresolved fine structures in solar atmospheres.

His publications highlight contributions to spectral line formation (e.g., Hϵ, Lyman series), clustering algorithms for spectral profile analysis, and computational tools like the RH 1.5D radiative transfer code. Collaborations span international teams, including studies of solar flares, UV bursts, and coronal heating mechanisms.
