Career Highlights
Dr. Dagher’s unique background & expertise in computational imaging allows him to solve problems at various portions of the imaging system pipeline including sensors, optics, signal/image processing and signal analysis. For example, Dr. Dagher applied these skills at Omnivision CDM Optics where he contributed to the design of the world’s first cellphone cameras. This effort included the development of lens elements and image processing algorithms for Low-Light imaging, Multi-Aperture imaging, Extended Depth-of-View imaging, and others. Dr. Dagher’s computational imaging capabilities allowed him to readily apply this system-wide philosophy in a wide range of imaging systems.
He is the inventor and published author on imaging technology found in consumer cameras (e.g., cellphones), biomedical imaging devices (e.g., MRI, microscopes), and warfare technology (e.g., LIDAR, RADAR, hyperspectral cameras). For example, Dr. Dagher developed an award-winning MRI technology (protocol sequence & image reconstruction method) that improves the detection of micro-hemorrhages (micro-bleeds) in the brain. During his tenure MITRE Corporation, Dr. Dagher helped develop a IED detection system using acoustic sensors & hyper-tuned signal processing methods that achieved detection rates up to 99%, thus enabling the technology to be integrated in theater.
Dr. Dagher’s career spans all professional sectors (academic, private industry and federal government) combining unique skills as innovator, teacher and product-delivery professional. Dr. Dagher was a Research Assistant Professor at Department of Medical Imaging at the University of Arizona, a Research Fellow at Harvard Medical School, a Senior Scientist at Omnivision CDM Optics and The MITRE Corporation, and now a Director of Research & Development at CHESS Solutions, where he enjoys leading a team of agile engineers to develop Deep Fake Detection and Media (Video/Image/Audio) Authentication technologies.
