Professional Experience

University of California, Riverside
Distributed Real-Time Systems Laboratory

Designing, implementing using Java and C++, and evaluating distributed protocols for sharing-aware component composition, load prediction and hot-spot alleviation, manage- ment of large-scale distributed real-time applications, and data dissemination in peer-to-peer systems. Leading the development of the Synergy distributed stream processing middleware; supervising other student research projects now using the platform.

IBM Research
T.J. Watson Research Center, Hawthorne, NY, Summer 2007

As a member of the advanced enterprise middleware group, designed, implemented in Java, evaluated, and documented a replication middleware for distributed, multi-tier, server architectures. Prepared a patent for the middleware's efficient, distributed strong consistency protocol. Quantified the server replication and data partitioning performance benefits, as well as the consistency overhead, using the TPC-W transactional web commerce benchmark.

Intel Research
Pittsburgh, PA, Summer 2006

As a member of the research team of the reliable email project, designed, implemented in C++, and documented an event-driven software prototype of a collaborative spam filter that employs a distributed protocol to defend against sybil attacks.

Hewlett-Packard
Enterprise Storage & Servers, Colorado Springs, CO, Summer 2005

As a member of the replication team of an upcoming product of HP's grid storage portfolio, designed, implemented in C++, and documented a logging mechanism used for asynchronous replication in a distributed disk array.

University of Patras, Greece
High Performance Information Systems Laboratory

Designed and implemented in C a protocol for dynamic memory page migration across the nodes of a Software Distributed Shared Memory System, as part of an inter-departmental diploma thesis. Dynamic page migration improves performance by increasing locality and adaptability, while remaining transparent to the application programmer.

FGAN e.V.
Bonn, Germany, Summer 2000

Analyzed the H.323 protocol family, used for multimedia applications (VoIP) in packet switched networks, and summarized the results in a technical report, including detailed protocol description and performance evaluation of applications under IPv6 in Solaris.
