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.
The Principal Investigators of SimBioSys are Profs. Avani Wildani and Ymir Vigfusson from the Emory CSI program, and Profs. Nosayba El-Sayed and Dorian Arnold are affiliated faculty.
