I am a Ph.D. student in the Computer Science Department at UC Santa Barbara and a member of the Distributed Systems Lab (DSL). I work at the intersection of data management and distributed systems in the area of Global-Scale Data Management. Also, I have worked in collaboration with HP Labs and Microsoft Research in the area of data management on emerging hardware technology.

Global-Scale Data Management: This line of work studies and design
transaction processing protocols for geo-replicated data. The large latency
between datacenters is a challenge to performance. This invites designing new
protocols that target geo-replication.

Data processing on emerging memory technology:
In collaboration with HP Labs, I worked on designing data stores for
non-volatile memory architectures. I studied the implications of emerging
flush-on-fail CPU technology on the durability cost of transactions. Also, as
an intern in MSR Redmond I worked on the Time-Split Bw-tree (TSBw-tree) that integrates
the algorithms of the Time-split B-tree within the lock-free implementation of the Bwtree.
Fair resource allocation for Wireless Mesh Networks: This project
tackles the problem of unfairness in Wireless Mesh Networks, where TCP flows
experience different performance characteristics depending on their location in
the network. A MAC-layer solution is developed to transparently improve TCP
fairness. The proposed MAC layer, called TMAC, uses a timestamp-ordering
technique to achieve fairness.
