Early-career researcher Dr.-Ing. Jiawei Sun honored with the Dr.-Ing. Siegfried Werth Prize

Dr.-Ing. Jiawei Sun, postdoc at the Chair of Measurement and Sensor System Technique (Czarske Lab), has been awarded the prestigious Dr.-Ing. Siegfried Werth Prize for his outstanding dissertation on “Learning-based Three-Dimensional Optical Cell Rotation Tomography and Quantitative Phase Imaging Using Multi-Core Fibers.” The Dr.-Ing. Siegfried Werth Stiftung foundation has awarded its annual prize to a scientific paper in the field of non-contact dimensional metrology since 1988. The prize is endowed with EUR 1,500.

In order to diagnose changes in biological cells and tissues caused by illness, a wide variety of instrumental examination methods are used today to provide image data of a patient's organs and structures, such as computer tomography or magnetic resonance imaging. Despite substantial breakthroughs in the optical imaging of biological samples, research in this area remains very active. Scientists around the world are trying to surpass the current spatial and temporal resolution, contrastive, and quantitative capabilities, particularly by incorporating fiber-optic technologies into minimally invasive endoscopy.

In his dissertation, Dr.-Ing. Sun investigated a multi-core, fiber-based dual beam dump that uses spatial light modulators to facilitate digital, program-operated three-dimensional cell rotation. He used an automated tomographic reconstruction workflow based on computer vision technologies and machine learning (including physics-informed deep learning) for a robust three-dimensional tomographic reconstruction of the rotated cell.

“Dr.-Ing. Jiawei Sun has done pioneering work on the non-contact rotation and examination of cancer cells, which can be transfered to biomedical applications. The latest artificial intelligence methods were introduced to fiber endoscopic tomography for the first time and used for image processing and generation,” explains Prof. Jürgen Czarske, Dr.-Ing. Sun’s Supervisor and Chair of Measurement and Sensor System Technique.

“I feel incredibly honored to have won the Dr.-Ing. Siegfried Werth Stiftung Prize. The prize encourages me to continue to pursue my research in the field of optical imaging and to improve existing test methods with the help of artificial intelligence and deep learning,” said Dr.-Ing. Jiawei Sun.

Dr.-Ing. Sun's research provides innovative methods for optical manipulation, tomography, and fiber endoscopic imaging with nanometer resolution and opens up new perspectives for future applications in biomedicine and microelectronics with minimally invasive keyhole access.
