Postdoctoral Research Fellow, 2015-present
Systems Researcher and PhD Candidate, 2010-2015

Demonstrated principles of design for systems on RDMA-capable datacenter networks by building high-performance distributed in-memory storage systems. Built the Cell distributed B-tree store and the Pilaf key-value store to demonstrated CPU efficiency and performance of RDMA-aware systems. Built Oolong, a distributed framework for asynchronous applications, building on the database concept of triggers. Sample applications including PageRank, SSSP, a web crawler, and Bipartite Matching show the interface simplicity and speed advantages for some problems over canonical Piccolo.

Research into data-centric distributed processing architectures. Extension of the Piccolo distributed computing framework to incorporate active triggers for efficient sparse parallel processing. Implementation of several classic Piccolo applications including a parallel NN trainer for face classification, as well as deep examination of performance breakdown compared with current leading software.
