  • Marios Georgiadis

    Marios Georgiadis

    Instructor, Radiology

    BioMarios is an Instructor of Neuroimaging, part of the Faculty of the Stanford University School of Medicine.

    His research focuses mainly on studying brain microstructure using cutting edge imaging (advanced X-ray, MRI, optical, and spatial biology approaches), with a particular focus on Alzheimer's disease hippocampi, neurodegeneration, and a special interest in myelin and iron.
    He is also actively involved in projects related to imaging and modeling brain trauma, exosome signatures of neurodegeneration, and imaging the brain using advanced forms of electron and light microscopy.

    His current research is being supported by NIH, the Alzheimer's Association, and the American Society of Neuroradiology.


    Marios is a mechanical engineer by training (School of Mechanical Engineering, National Technical University of Athens, Greece). His thesis "Closed-loop force control of a haptic surgical simulator", was performed in the Control Systems Lab of Prof. Evangelos Papadopoulos.

    In 2011 he obtained his MSc in Biomedical Engineering from ETH Zurich (Swiss Federal Institute of Technology). He performed his thesis in IBM Research on "Advanced pathology using the Microfluidic Probe", under Emmanuel Delamarche and Govind Kaigala, and was awarded the ETH medal for this work.

    He completed his PhD in Bone Biomechanics in the lab of Prof. Ralph Muller in ETH Zurich, where he developed X-ray scattering-based methods to investigate bone microstructure in 3D, research that earned him the 2nd Student Award from the European Society for Biomechanics in 2015.

    In 2016 he started using imaging methods to study brain microstructure, in the lab of Prof. Markus Rudin, in the Institute for Biomedical Engineering of ETH Zurich. There, he combined X-ray scattering with DTI, histology and CLARITY for studying rodent brain.

    In 2017 he joined the MRI Biophysics group of Profs. Els Fieremans and Dmitry Novikov in New York University School of Medicine, to study human and mouse brain microstructure using X-ray scattering and diffusion MRI.

    He is in the Translational Neuroimaging lab, headed by Dr Michael Zeineh, since 2019.

    His research on myelin in mouse and human brain using X-ray scattering has been supported twice by the Swiss National Science Foundation.
