Gabriel Popescu, Ph.D.

WASHINGTON, D.C. — The American Institute for Medical and Biological Engineering (AIMBE) has announced the election of Gabriel Popescu, Ph.D., to its College of Fellows. Dr. Popescu was nominated, reviewed, and elected by peers and members of the College of Fellows for pioneering contributions in interferometric and quantitative phase imaging to assess the nanoscale tissue architecture and dynamics of live unlabeled cells.

The College of Fellows is comprised of the top two percent of medical and biological engineers in the country. The most accomplished and distinguished engineering and medical school chairs, research directors, professors, innovators, and successful entrepreneurs comprise the College of Fellows. AIMBE Fellows are regularly recognized for their contributions in teaching, research, and innovation. AIMBE Fellows have been awarded the Nobel Prize, the Presidential Medal of Science and the Presidential Medal of Technology and Innovation and many also are members of the National Academy of Engineering, National Academy of Medicine, and the National Academy of Sciences… Continue reading.

Researchers at the University of Illinois Urbana Champaign have developed a new technique that combines label-free imaging with artificial intelligence to visualize unlabeled live cells over a prolonged time. This technique has potential applications in studying cell viability and pathology.

The study “Phase imaging with computational specificity (PICS) for measuring dry mass changes in sub-cellular compartments” was published in Nature Communications.

“Our lab specializes in label-free imaging, which allows us to visualize cells without using toxic chemicals,” said Gabriel Popescu, a professor of electrical and computer engineering and the director of the Quantitative Light Imaging Laboratory at the Beckman Institute for Advanced Science and Technology. “However, we cannot measure specific attributes of the cell without using toxic fluorescent dyes. We have solved that problem in this study… Continue reading.

A collaboration between researchers at the University of Illinois at Urbana-Champaign and Colorado State University resulted in a new 3D imaging technique called harmonic optical tomography that facilitates the visualization of tissues and other biological samples on a microscopic scale.

The technique can potentially be used to assist with diagnosing cancer and other diseases. The technique is based on using holographic information, which measures light patterns, to generate 3D images of a sample. Three-dimensional imaging that can peer into the interior of an object provides critical information for a diverse range of applications, such as medical diagnostics, finding cracks in oil wells and airplane wings, using tomographic X-ray, and ultrasound methods… Continue reading.
