Retinal Image Research

The research of dr. C.I. Sánchez’s group focuses on developing automatic solutions for medical image interpretation, particularly retinal images, with the aim of bringing technology to clinical practice in order to provide better health care. Her goal is to make healthcare more efficient and affordable by increasing automation of diagnostic and therapeutic procedures and freeing manpower for those areas in patient care in which the "human touch" is most needed. Clara Sánchez  received her PhD degree in 2008, cum laude, with a work on automatic analysis of fundus images for cost-efficient diabetic retinopathy screening. From 2010 to 2013, she was tenured at the Diagnostic Image Analysis Group (DIAG) in the Radboud University Medical Center (www.diagnijmegen.nl). Since September 2013, she leads the retina image research group at DIAG and in July 2016 she became associate professor in advanced machine learning for medical imaging. The retina image research group focuses on the development of computerized techniques for the analysis and interpretation of retinal images in order to 1) provide an automatic eye diagnosis for cost-efficient screening programs and 2) extract quantitative image biomarkers that can help in the diagnosis and clinical research of eye diseases. Other interests are automatic analysis of chest radiographs for the diagnosis of tuberculosis and pattern recognition and machine learning for medical images.
