I worked with Nir Shavit on a computational neuroscience project - we're extracting a full connectome (3D map of a brain, with all neurons, synapses etc.) of a mammalian brain. Majority of my work is at the intersection of "big data", machine learning (computer vision/image segmentation) and concurrent algorithms.
