Design and execute large-scale, multi-area neural recording experiments in awake, behaving subjects performing complex perceptual, working-memory, and higher-cognitive tasks, using high-density Neuropixels probes, chronic polymer probe arrays, two-photon imaging, and holographic optogenetics. Experimental work combines large-scale neural recordings, targeted stimulation, and behavioral design, working closely with computational, engineering, and software teams to translate biological insight into a detailed model of the brain that can guide causal perturbation experiments and inform new AI architectures.
