• unknown (b.)


A computer scientist and software researcher, he retired from IBM's Thomas J. Watson Research Center in Hawthorne, New York at the end of February, 2009, and now works independently under the name Internet Messaging Technology. His work has focused for many years on electronic mail and anti-spam technology, on mobile computing, and on Internet standards. His interest in e-mail began in the early 1980s, with IBM's PROFS system, and with a proprietary e-mail system developed for an IBM customer. In the early 1990s he and his team at IBM Research developed an early implementation of an integrated multimedia e-mail system, called Ultimail, which became part of IBM's TCP/IP product for OS/2. The work on Ultimail led to development of the Internet Messaging Framework, a toolkit for developing Internet-standards-compliant clients and servers. He was part of the team that developed the SpamGuru anti-spam engine at IBM Research. He has published a number of papers at the Collaboration, Electronic messaging, Anti-Abuse and Spam Conference, and was a program chair for the conference in 2008 and 2010. He has been involved with the Internet Engineering Task Force since the mid-1990s, working on e-mail-related standards, including IMAP, ACAP, updates to SMTP and the Internet message format, lemonade, the Sieve e-mail filtering language, internationalization in general and e-mail address internationalization in particular, and DKIM. He is co-chair of the DKIM, VWRAP, and MARF working groups, and served on the Internet Architecture Board from 2007 to 2009. He is currently the IETF liaison to the Messaging Anti-Abuse Working Group (MAAWG). He has also worked on IBM Research projects involving context awareness, mobile and distributed computing, and computer security and access controls. He has edited the "Standards" department for the IEEE Computer Society's Internet Computing magazine since January 2008, and was appointed to the magazine's editorial board in March 2008.
