Recent Work

Currently my interests lean toward real-world communications traffic measurements, particularly for wireless networks, that can be obtained on a regular basis to support network performance, service level agreements (SLAs), and traffic management for new and complex mixtures of user applications. My recent work in traffic engineering and performance analysis concentrated on extensive specialized analyses of unique high-resolution traffic traces, collected from working Frame Relay, SS7, ATM, and IP networks, to support engineering guidelines related to safe utilization levels and multiplexing gains.

Earlier Work

In the mid-1990s, I was the lead Bellcore performance analyst of operator/call center teams, providing technical consultation on the implementation of Bellcore's operator force management algorithms for staff sizing, in addition to consulting related to queue arrangements, team organization, call deflection settings and other operational issues which affect quantitative service objectives such as speed of answer.

Much of my career at Bellcore, and previously at Bell Labs, Murray Hill, was spent in the marketing science applications area, combining the disciplines of statistics, psychometrics, economics, and marketing, to perform quantitative analyses to support telecommunications decision-makers in diverse organizations such as network planning, engineering, force administration, tariff design, regulatory, product management, advertising and marketing. Because of my contributions in this work area, I was presented the Distinguished Member of Technical Staff award in 1989.

I have presented my work at conferences of the IEEE, the American Statistical Association, and the Institute for Operations Research & the Management Sciences (INFORMS). I was a speaker for the Women and Mathematics Program (1980-1982), and a lecturer in demand analysis techniques at the Bellcore Training and Education Center (1987 and 1989). I have also given numerous presentations at annual Telecommunications Forecasting Conferences and Business Research Conferences.
