Biographical Sketch

Andy Wang received his Ph.D. and M.S. in computer science from UCLA in 2003 and 1998, and his B.S. from UC Berkeley in 1995. He joined the Department of Computer Science at Florida State University as an Assistant Professor in 2003. His research interests include file systems, optimistic peer replication, performance evaluation, ad hoc network routing, operating systems, and distributed systems.


Research

Andy Wang's research theme revolves around the management of data flows. His research on energy-efficient storage (Conquest-2) involves redirecting requests to data replicated at unused portions of disks, thereby creating opportunities to power down disks and save energy. His invention of electric-field-based routing allows mobile computers to form disjointed communication paths without explicit coordination and global knowledge. The Conquest disk-persistent-RAM file system uses specialized data paths to memory and disk storage to achieve drastic performance improvements. His invention of permutes states offers a compact representation of distributed systems with an exponential number of states and thus can be applied to analyze optimistic replication systems with an exponential number of ways to propagate data updates. His work in real-time storage domain involves throttling the data flow to meet timing constraints.
