Our Management Team

Sine Nomine Associates consists of talented individuals led by a distinguished senior management team.

E. Margarete Ziemer — CEO

E. Margarete Ziemer, Ph.D., is co-founder and CEO of Sine Nomine Associates. Together with the company's CTO, she built an elite team of engineers, each with over fifteen years of industry experience and each being a published author and respected expert in his/her field. Having helped invent Linux on the mainframe, Sine Nomine Associates remains the leader for server consolidation using that technology. Sine Nomine Associates regularly contributes software to the Open Source community and supports commercial users of open systems, including the largest public-sector implementation of OpenAFS (Andrew File System) in the world. Sine Nomine Associates also maintains and supports aging, sometimes esoteric, technologies which are often ignored or discarded by vendors but remain mission-critical for businesses. Her vision and focus helped establish this company as a trusted partner for advising, improving, and supporting Fortune 500 companies in their business success.

Dr. Ziemer, a resident of former East Germany for twenty-five years, brings extensive international and academic experience to Sine Nomine Associates. In addition to four master’s degrees (or equivalent), she received a post-graduate degree at the University of Jena, Germany, and a Ph.D. at Princeton. Along with merit-based scholarships, she was awarded grants by the Fulbright Commission, the World Council of Churches, and the American Association of University Women.

David Boyes — President and CTO

David E. Boyes, Ph.D., is the co-founder, President and CTO, and principal design engineer at Sine Nomine Associates. He has over 25 years of experience in the data communications, system operations, and technical/business strategic planning environments at the enterprise and carrier-class level. In his various positions, he has acquired in-depth knowledge of a broad range of technologies, including Internet systems, network and system performance management, network and system design and planning, and network and system security.

Mr. Boyes’ focus is a full life cycle of design, engineering, deployment, and operations for large-scale systems and operations facilities. His extensive experience with systems and network integration provides a strong baseline for design and implementation, to the level of working both with customers and with vendors to promote better solutions (including large vendors such as IBM and Ascend). His passion and excellence lie in enterprise operations and management, with a strong background in Tivoli and HP OpenView NNM experience. As the Project Manager for the Internet Applications Project SHARE Users Group from 1994 to 1997, he served as the direct interface with IBM executives on strategic direction and product direction, content, and offerings. One of his outstanding accomplishments was his contribution as lead researcher in combining the flexibility of Linux with the reliability of the IBM mainframe environment, thereby breaking ground for a new era in enterprise-level technology.

Mr. Boyes holds a doctorate in economics from the University of Houston, master’s degrees from Oxford University and University of Oregon, and bachelor’s degrees from the University of Oregon.
