Yali Jia, PhD
Associate Director

Dr. Yali Jia is an Associate Professor of Ophthalmology and Biomedical Engineering at the Oregon Health & Science University (OHSU). Dr. Jia earned her PhD in Biomedical Engineering from OHSU in 2010 under the guidance of Dr. Ruikang Wang. Dr. Jia completed her post-doctoral training with Dr. David Huang at Casey Eye Institute in 2013. She developed split-spectrum amplitude de-correlation angiography (SSADA), a highly efficient OCTA algorithm that made clinical OCTA practical. Dr. Jia was awarded 3 NIH research project grants that supported the initial works that demonstrated clinical applications of OCTA in retinal diseases. She is the technical leader in Casey Reading Center.  Her OCTA reading software (COOL-ART) has been used by several large clinical studies and many international collaborators. She has published ~80 peer-reviewed journal articles and 25 book chapters; and co-edited 3 books.  Her major contributions to OCTA community are: efficient OCTA, quantitative OCTA, projection-resolved OCTA and motion-free OCTA.
