Research Interests
Ali received his Ph.D. degree in Electrical and Computer Engineering from Purdue University in 2006. Ali is a recipient of an NSF CAREER Award (2008), an IBM Faculty Award (2008), a VT College of Engineering (COE) Dean's award for "Outstanding New Assistant Professor" (2009), an IBM Shared University Research Award (2009), and NetApp Faculty Fellowships (2011, 2015). Ali was named a VT COE Faculty Fellow in 2013. He has served as the Associate Editor for IEEE Transactions on Parallel and Distributed Systems (2013--present) and Sustainable Computing: Informatics and Systems (2010--present). He was selected to participate in National Academy of Engineering's USFOE Symposium in 2009, USJFOE in 2012, and also as an organizer for the USFOE in 2010. Ali's research interests are in operating systems, distributed systems, file and storage systems, cloud computing, grid environments, peer-to-peer systems, and self-organizing systems. At Virginia Tech. he leads the Distributed Systems & Storage Laboratory (DSSL).
Distributed Systems and Storage LaboratoryURL: http://research.cs.vt.edu/dssl/ DSSL is interested in the design, development, and evaluation of next-generation storage and file systems. Specifically, the research focuses on tailoring these systems for growing data demands of modern high-end computing applications running on existing as well as emerging multicore architectures. To this end, we aim for innovation in systems that range from large-scale distributed setups to specialized kernel-level optimizations. |
