Dr. Tabor and his colleagues use genetically engineered E. coli that are sensitive to light to create incredibly detailed images of shapes, people, and other subjects. You can find out more about their work here, here, here or here, and read their Nature paper here.
The members of the creative team are:
Dr. Jeff Tabor, a postdoctoral fellow in the Voigt Lab at the University of California San Francisco, USA. His current work involves using light to engineer unnatural behaviors into communities of bacteria.
Aaron Chevalier, a graduate student in Biomedical Engineering at the University of Texas at Austin. As an undergraduate he developed the light projection technology used to produce the bacterial photographs.
Dr. Chris Voigt, an Associate Professor studying synthetic biology at the University of California San Francisco. His work broadly involves programming living cells for novel functions. For example, he has engineered microbes to invade tumor cells, produce biofuel precursors and spider silk, and to genetically respond to light.
