Personal Bio

Siamak Ardekani is a member of the research faculty in the Department of Biomedical Engineering and Center for Imaging Science at Johns Hopkins University. With a background in medicine and medical imaging Ardekani focuses on developing computational models to extract clinically relevant information from medical images, generated through magnetic resonance imaging and computed tomography, that are used to quantify and visualize alterations in the shape and function of anatomical structures, such as the brain and heart. Models developed by Ardekani have the potential to assist physicians in identifying patients that are at a high risk of complications and monitor these patients’ responsiveness to therapy.

Ardekani earned his PhD in biomedical engineering from the University of California, Los Angeles, an MD from Shiraz University of Medical Sciences, and as MS in biomedical engineering from Drexel University. He has authored more than 20 research journals and conference papers in international journals and conference proceedings.
