Ganna Blazhenets, PhD

Assistant Researcher

I am an early-career scientist with a background in physics and neuroimaging, completed my PhD at the University of Freiburg in Germany, focusing on multimodal neuroimaging techniques. In 2022, I began my journey as a visiting scholar at the Rabinovici lab, returning in 2024 as an assistant researcher.
My expertise lies in utilizing advanced analytical methods and state-of-the-art neuroimaging techniques to understand the mechanisms of neurodegeneration. My goal is to identify factors driving neurodegenerative disorders, aiming to improve early diagnosis, treatment, and prognosis for patients.
