Department of Computer Science
The Emory SimBioSys Lab is a partnership of computer science researchers studying Distributed Systems, Data Science, and their intersections. Our projects span smarter cache system, computational epidemiology, distributed end-to-end tracing, storage systems analysis, computer security, biologically plausible neural networks, and the theory of learning. We particularly care about projects with societal impact.
