Graphics Imaging & Light Measurement Laboratory, Barnard College, Columbia University.

The Graphics Imaging & Light Measurement lab develops new imaging techniques and analysis algorithms in Computer Graphics and Vision for applications in Life Science, Bio-Medical Research and Archaeology. Recent developments in deep learning, combined with the recent influx of affordable optics-based imaging technology is making a wide range of new data formats available to researchers for scientific analysis of real objects.

As these technologies become more prevalent, scientists are discovering the need for new forms of investigation never before considered in computer graphics research. These examples are opportunities to re-think several problems in computer graphics and develop new ways of seeing, representing, and navigating information.
