Sina Shirinpour

Postdoctoral Associate

  • PhD in Biomedical Engineering, University of Minnesota, USA
  • BS in Electrical Engineering, University of Tehran, Iran

Sina’s research interest is in developing innovative methods for transcranial magnetic stimulation (TMS). He is interested in improving the efficacy of stimulation through the use of a TMS-EEG closed-loop system. Such a system would allow to pick up biomarkers and deliver TMS to the brain at the right time. Furthermore, he is developing multi-scale modeling platforms to study the effects of neuromodulation on single neurons. Using this technique, the macroscopic, microscopic, and subcellular behavior of neurons can be investigated. Additionally, he is working on extending the visualization and graphical user interface of SimNIBS.
