Expert is a recognized expert in Internet standards, having written a number of standards in the IETF, including a number of SIP (VoIP), peer-to-peer, cloud computing, and messaging standards. In addition, he chaired a number of work groups developing Internet electronic-mail, speech server control, and media server control protocols. Five of his twelve issued US patents are in the area of Internet communications. Moreover, he has journal and conference papers in the domain. Expert is also known for his work in the Voice-over-IP area, having been the Chairman of the SIP Forum, served on the Board of Directors of the IMS Forum, and was an Advisor to the VoIP Forum of Japan. Expert was a founder of SnowShore Networks, where he invented the multifunction SIP-controled Media Server. This network element brought the Internet software development model to real-time, interactive multimedia applications, such as conferencing, Interactive Voice Response, and messaging. This is today the dominant model for communications applications development. Expert sold SnowShore to Brooktrout (NASD:BRKT) where he was CTO. Brooktrout sold to Cantata, where he also was CTO.

Expert also served as Deputy CTO at BEA Systems, the leading provider of Internet infrastructure software for carriers and enterprises, until BEA's sale to Oracle.

Expert successfully defended a large network equipment manufacturer from a patent suit by a troll in 2009. This required a deep dive into his large network of technology practitioners to demonstrate a circa-2000 Voice-over-IP system that was concrete evidence of prior art. Besides his technical summary, his analysis of the ownership documents was a conclusive piece of evidence that resulted in the defendant getting an outright win in the court.

Expert started in telecommunications over twenty years ago, consulting to MCI and later working for Cable & Wireless in development engineering. He turned around a network equipment manufacturer which he successfully sold to Centigram (NASD:CGRM), which he went on to sell to ADC. These platforms were highly network-centric, both in terms of being a critical part of the SS7 network, as well as being built of SS7 and TCP/IP components integrated together. Moreover, they provided enhanced services such as interactive voice response, conferencing, advanced telephony, and voice/data convergence. Working both at a carrier and at equipment manufacturers put Expert in the heard of strategic planning for network deployment and evolution.

Seven of Expert's issued patents are in the areas of communications, computer networking, telecommunications, and enhanced services.

Expert managed the SureFax group at Cable & Wireless, which was one of the global leading store-and-forward and broadcast facsimile providers. Later, Expert was CTO at Brooktrout Technology, which was the global leader in facsimile enabling technology (fax boards and software) and the source of the T.38 Fax-over-IP specification. Currently, Expert is involved with the SIP Forum's FoIP interoperability work group, working on how to improve T.38 interoperability through the use of enhanced SIP signaling.

Expert is a Member of the Board of the Public Interest Registry, the operator of the .ORG, .NGO, and .ONG top level DNS domains. Expert, through his tenure as CTO at Neustar, is familiar with the North American local number porting, pooling, and number administration process, regulations, and government agencies, such as the FCC. Expert has regular visits to Capitol Hill to meet with Congressional staff, as well as to brief agencies such as the FCC on communications and Internet technology matters.

Expert is the Chair of the IEEE-USA Committee on Communications Policy, the policy arm of the Institute of Electrical and Electronics Engineers in the United States.

Expert has a track record of computer software technology innovation. He has transformed four companies from being primarily hardware companies into software companies. He has numerous software patents issued in the United States. As CTO of public companies, his charter was to enable innovation through active policies, corporate engagement, and enrollment of the rank-and-file to create a culture of innovation.

On the relational database front, Expert taught data base theory at George Mason University and George Washington University, as well as creating numerous data base-centric real-time and near real-time systems and applications. Four of his patents leverage relational data base technologies, used in novel ways, to offer what were, in their day, extremely advanced telecommunication services.

Provided winning technology analysis and contract analysis in a patent litigation suit.Provided due diligence for late-stage investment in a network equipment and service provider. Whilst the company did not accept the investment at the last minute, all of his predications were accurate.Provided strategic research planning and product direction for a large network equipment manufacturer, resulting in a new line of products and solidified their market position.Provided insights and operating principles to assist a hosted voice services application provider to migrate from a working prototype of a service to a reliable, commercial service.Provides regular advice to investment bankers and financial analysts on the state of the Internet and telecommunications industries as well as on individual companies. He often provides the context and behind-the-scenes analysis to frame the different player's potentials and market evolution.

Expert may consult nationally and internationally, and is also local to the following cities: Baltimore, Maryland - Frederick, Maryland - Gaithersburg, Maryland - Bowie, Maryland - Richmond, Virginia - Alexandria, Virginia - Wilmington, Delaware - Lancaster, Pennsylvania
