Scientific Advisory Board

The Scientific Advisory Board (SAB) provides strategic guidance and direction for VisualSonics technology and plays a key role in guiding and prioritizing our global research investments. The board provides VisualSonics with a unique opportunity to shape the future of basic and clinical research, while continuing to focus on filling our customer needs, by recommending promising scientific and technical developments for practical applications with the VisualSonics product and application offerings.

The SAB is guided by members of the VisualSonics global leadership team and consists of leaders in the fields of cardiovascular research, bioengineering, molecular imaging, and ultrasound and photoacoustic technology. A brief overview of current board members can be found below:

Dr. Stuart Foster

Dr. Stuart Foster, PhD

Senior Scientist, Sunnybrook Research Institute, Professor, University of Toronto

Board member duration:
Duration: 2020 - Present


Dr. F. Stuart Foster is currently 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.

Dr. Roger Zemp

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

Craig Goergen

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.
