Board Certified Family Practice Medical Expert Witness

Expert No. 749




A comprehensive understanding of networks, computers, and communications--down to the packet, byte, and bit levels--started with a degree in physics.  Membership in the IEEE Communications Society has kept my knowledge at "state of the art" and contributed to successes in network architecture and design for government agencies, carriers, and enterprises.  My insight into technology and user needs produces unique, practical solutions.  Working for two communications hardware vendors, I often designed proposals and solutions to support network sales.  Recruited by a consulting firm, I documented large portions of a model enterprise network architecture, including white papers, market analysis, and "best practice" documents.  After starting my own firm, I designed major voice and video networks, advised carriers and hardware manufacturers, and prepared reports and proposals for Federal contractors.  I supported USDA in IT procurements, setting standards, and developing IT governance policy.  My background check is for a public trust position.


Professional Skills

Creating optimal network solutions based on business needs and the best available technologies, then presenting a proposal to gain acceptance by stake holders.
Advisory consulting to senior managers.  Concise information delivered in understandable form, with appropriate context to enure information is usable.
Writing with clarity on business and technical issues.  Clear presentations of complex materials have gained acceptance of proposed network solutions, completed procurements, and ensured a successful IPO.  My six books on networks have sold over 70,000 copies;  the latest, on VoIP, was published in 2012.  
Analysis and interpretation of as-is situations, business requirements, and available technologies to find a viable technical solution for the future.  
Market analysis of networking services and communications devices to identify high-potential products and prevent investment in those likely to fail.
Procurement processing for the Federal Government.  My statements of work and RFPs, bid review processes, and support during bid evaluations have overcome multiple protests to see projects awarded, deployed, and working.  Experienced with proposals.
Consensus building around an optimal technical solution based on  real needs, researched options, facilitated meetings, and presentations of the proposal to stakeholders.
Public speaking on business and technical subjects, including preparation of slides and handouts.  I have delivered over 200 industry conferences and seminars to educate, train, establish strategy, and promote products and solutions.


Knowledge Areas

Data network architecture and design to link computers, terminals, and specialized devices over local and wide areas;  includes all transmission technologies, old and new protocols, and migration strategies.  
Telephony and voice processing, including digital encoding of voice and images,  switching, conferencing, VoIP, UC, SIP, communications servers, gateways, and many form of analog and digital signaling.
FAR as applied to Federal network and IT acquisition.
Product design for multiplexers, routers, and other networking devices.
Security for networks, computers, and applications, including firewalls, authentication, admission control, and encryption.
