Joonas Laurinoja is a Doctoral Researcher of CNIR group at A.I. Virtanen Institute for Molecular Sciences, University of Eastern Finland in Kuopio, Finland. He possesses a strong interest in multimodal neuroimaging and has extensive experience in the acquisition and processing of EEG data in conjunction with (f)MRI. His research focuses on developing a closed-loop brain stimulation system that integrates the use of TMS, EEG, and fMRI techniques. The goal of this system is to improve and personalize TMS treatment planning strategies by utilizing real-time feedback about neural activity and connectivity. Specifically, his work aims to leverage the spatial and temporal resolution of fMRI and EEG to guide TMS targeting and optimize stimulation parameters. By combining these modalities, it is hoped that more effective and individualized treatments for neurological and psychiatric disorders will be provided. He is also a Visiting Researcher in the TMS group led by Prof. Risto Ilmoniemi at Aalto University in Espoo, Finland.
