Board member duration:
Duration: 2020 - Present


    Dr. Foster is a senior scientist at Sunnybrook Research Institute and Professor, Department of Medical Biophysics, University of Toronto.​

    His pioneering inventions in the field of micro-ultrasound have enabled powerful high-resolution noninvasive imaging for the study of disease development and the translation of micro-ultrasound to clinical applications; Stuart is a Fellow of the IEEE, the American Institute of Ultrasound in Medicine, the Royal Society of Canada and the Canadian Academy of Engineering.​

    He is the founder and former Chairman of FUJIFILM VisualSonics Inc., a company dedicated to preclinical and clinical micro-ultrasound.​

    He has previously been the recipient of numerous distinctions in biomedical engineering including the Eadie Medal, the Queen’s Golden Jubilee Medal, the Manning Award of Distinction for Canadian Innovation, the Ontario Premier’s Discovery Award, and the IEEE Rayleigh Award. He was elected to foreign membership of the US National Academy of Engineering in 2017 and received the 2020 Biomedical Engineering Award from IEEE.

    • Applications of micro-ultrasound in medicine and biology
    • Microbubble and nanoparticle biophysics
    • Molecular imaging and photoacoustic imaging


    Dr. Roger Zemp, PhD

    Professor, University of Alberta

    Board member duration:
    Duration: 2020 - Present


    Dr. Roger Zemp is a world-leading researcher in ultrasound and photoacoustic imaging technology development.

    He earned his PhD from UC Davis in 2004 and completed a postdoctoral fellowship at Washington U. in St. Louis in 2007. He pioneered photoacoustic molecular imaging and the development of a new form of microscopy, photoacoustic remote sensing microscopy and its use for virtual histopathology.

    He also has pioneered the development of bias-switchable row-column 2D arrays enabling 3D or steerable 2D imaging with a band-aid-sized patch. This technology is enabling improved 3D ultrasound and photoacoustic imaging. He has furthermore developed a substantial program in microfabricated ultrasound transducers with industry partners and pioneered row-column arrays, multi-frequency arrays, transparent arrays, and flexible arrays.

    He has published over 100 peer-reviewed journal papers and over 230 conference papers. He is co-chair or program committee member of various conferences in biomedical optics and ultrasonics and associate editor of 4 journals.

    Dr. Craig Goergen, PhD

    Leslie A. Geddes Associate Professor, Weldon School of Biomedical Engineering, Purdue University

    Board member duration:
    Duration: 2020 - Present


    Dr. Craig J. Goergen is the Leslie A. Geddes Associate Professor in the Weldon School of Biomedical Engineering at Purdue University in West Lafayette, Indiana, USA. He holds a BS in Biomedical Engineering from Washington University in St. Louis and MS and PhD degrees in Bioengineering from Stanford University. His postdoctoral training in molecular optical imaging at Harvard Medical School focused on cardiac disease and left ventricular remodeling.

    After joining the faculty at Purdue University in December of 2012, Dr. Goergen has worked to establish the Cardiovascular Imaging Research Laboratory. His group’s mission is to advance imaging techniques to study disease progression and improve detection and treatment across a broad spectrum of medical conditions.

    Under his guidance, the laboratory initially focused on developing imaging techniques to study both cardiac and vascular disease, but current efforts have taken a more expansive approach, including research projects from cancer to diabetes.

    Dr. Goergen’s overall aim is to advance the field of imaging to help diagnose, treat, or prevent disease, ultimately providing patients with longer and more fulfilling lives.

    • Photoacoustic imaging using endogenous contrast
    • Multimodality small animal imaging

    Dr. Fabian Kießling

    Dr. Fabian Kießling

    Professor Director, Institute for Experimental Molecular Imaging (ExMI) at RWTH Aachen

    Board member duration:
    Duration: 2022 - Present


    Dr. Kiessling is a full professor and director of the Institute for Experimental Molecular Imaging (ExMI) at RWTH Aachen (Rheinisch-Westfälische Technische Hochschule Aachen). He is also one of the directors of the RWTH Helmholtz Institute for Biomedical Engineering.​

    His research focusses on the development of new imaging methods and probes, with a particular focus on oncology and diseases that go along with angiogenesis and vascular remodeling. He worked on the imaging technique volumetric area detector computed tomography and published the new ultrasound technique Motion Model Ultrasound Localization Microscopy (mULM) together with his colleague Georg Schmitz.

    The ultrasound technique was preclinically tested and used in a first clinical application. Both methods allow non-invasive imaging of hair-thin blood vessels in tumors and other tissues.

    In his translational research, imaging-guided therapy plays an important role including the investigation of biological barriers for drug delivery and the development of strategies to overcome these barriers by the use of nanomedicines, drug delivery systems, and other therapeutics.
