Responsible for information about Bell Labs research.

We accomplish this through the corporate electronic library that holds all relevant information spanning a century of data, the Bell-Labs.com site for external communications of notable activities and history (1/2M page views/year), content curation, other multimedia and electronic media, publications, and more. 

Less recent accomplishments include development of an IPTV advertising solution, innovations in optical fiber manufacture, and basic research in molecular beam scattering.
