With a solid academic foundation built at the University of Oslo, Aline's work combines curiosity and the drive to uncover cosmic mysteries.

Originating from Moss, Norway, she earned both her bachelor's degree in physics and astronomy and her master's degree in astronomy at the University of Oslo. Throughout her studies, she was drawn to the complexities of the cosmos, particularly the enigmatic nature of our Sun.

Delving into micro- and nanoflares 

Beginning her work at RoCS in autumn 2024, her research focuses on understanding the micro- and nanoflares on the Sun.

I'm utilizing machine learning techniques to detect these small solar explosions in images

she explains. By determining their frequency, we hope to gain insights into why the Sun’s outer atmosphere is so much hotter than its inner layers—a mystery known as the coronal heating problem.

Innovative methods in solar research

Her approach includes using synthetic observations from simulations run with ITA’s BIFROST code, alongside real observations from the Swedish Solar Telescope (SST). - Merging simulation data and real observations with machine learning presents new avenues for analyzing solar activity, she explains.

Choosing RoCS for growth and learning

Her choice to pursue a PhD at RoCS stems from the supportive academic community she experienced during her master's studies.

RoCS, and ITA at large, offer a wealth of knowledge and exciting opportunities

she reflects. The environment is conducive to tackling complex research endeavors.

Anticipation for new discoveries

Reflecting on her journey so far, she expresses her excitement and eagerness to progress. - I am just beginning to explore the depths of my project, and I look forward to how it will evolve over the coming years, she shares. Each discovery leads to new questions and opportunities.

Interests beyond work

Outside of her research, she enjoys a wide range of activities, including reading, playing music, photography, and engaging in video and board games. - These hobbies provide a creative outlet and balance to my scientific work, she says.

We are thrilled to have her at RoCS and eager to see her achievements in the field of solar physics.

Welcome aboard, Aline!
