MIT Media Lab

Christopher is a Postdoctoral Associate in the Camera Culture group at the MIT Media Lab. He earned his Ph.D. in electrical engineering from Princeton University for his work integrating nonlinear wave physics with optical imaging. A key research interest is exploiting the properties of nonlinear propagation, which couples the different spatial and spectral components of a signal, for use in computational optics. Currently, he explores ultrafast optics and advanced numerical algorithms for development of novel tools in imaging and sensing. He can be reached at cbarsi@media.mit.edu
