As Senior Network Scientist I conducted research in Networks, Network Operations, Network Management, Network Monitoring, Communications, Distributed Systems, and Infrastructure.

As PARC's Network Manager I had direct operational responsibility for PARC's Network and the Network Support Staff.

• Network and computing infrastructure planning, evaluation, design and implementation.
• Management and oversight of PARC's Network and Network Support group.
• Research in network design, performance, mobility, management, functionality, and operations.
• PARC and Xerox Expert Resource for network and distributed systems issues.

Some key projects:

New Network	Designed, deployed, and manage a complete replacement of the center's networking infrastructure. This new network is very high performance, flexible, and robust. It supports 10/100 mbps and gigabit Ethernet, 100% switching, hardware routing at switching speeds, "universal port" intelligent VLANs, and multicast. Robustness is central to the design at virtually all levels. Custom network management greatly reduces workload by automating many tasks that typically require a sizable network support staff.
Wireless	Design, test, and deploy a new center-wide wireless network access using the 802.11b standard with an emphasis on coverage, performance, and security.
Web Tools	Designed and implemented a web-based network management system that integrates a wide range of network, system, and facility information into a rich, unified, yet simple user interface.
