My research focus is generating novel insights into ophthalmic disease with advanced OCT image reconstruction. I presented at international conferences like MICCAI and ARVO, including 7 oral presentations, and was awarded an Editor’s Pick by Biomedical Optics Express, a journal curated by leading OCT experts. Furthermore, I contributed the chapter OCT motion correction and volume fusion to the upcoming third edition of the standard reference work Optical Coherence Tomography (book). My work is extensively evaluated in clinical data, and utilizes algorithmic and low level GPU optimization to minimize runtime.

Measurement of blood flow speeds in retinal capillaries

In 2015, OCT angiography was just commercialized to map the structure of the retinal vasculature. In collaboration with researchers at MIT, I developed the first method for plexus-specific visualization of blood flow speed accross full-size enface OCT angiography images, Variable Interscan Time Analysis (VISTA) visualization (Retina, 2016). The method was patented, orally presented at the ARVO annual meeting 2016 in front of an audience of ~1000 experts, applied in multiple clinical publications, and attracted attention of several research groups worldwide.

Advanced ophthalmic imaging with Volume Fusion OCT

OCT volume fusion enhances the visibility of retinal bands.

Especially OCT images from elderly subjects suffer from eye motion, distortion, opacities, and low SNR. I developed a unique framework for automatic artifact compensation and image enhancement. Multiple OCT volumes are seamlessly fused and optionally super-resolved in 3D to reach unprecedented image quality. The approach was transferred to four collaborating institutes and played a key role in multiple clinical studies, enabling the first in-vivo topographic analysis of Basal Laminar Deposits and unvealing a new, particularly weakly reflecting band in OCT, among others. Milestones, which together form the Motion correction and volume Reconstruction in OCT (MoReOCT) framework, are listed below.

Collaborations with pioneering international experts

Since my research visit in 2015/2016, I am closely collaborating with James Fujimoto’s research group at MIT, who built the first and continue to develop most advanced OCT systems to date. Our joint developments are transferred to clinical application at the New England Eye Center (Nadia Waheed, Jay Duker), the first clinic that used OCT technology in patient care. I’m also studying new technologies with researchers at Oregon Health and Science University (Siyu Chen, David Huang) and Northwestern University (Hao Zhang).
