I'm a baby-boomer Canadian currently working in China. I've spent two substantial chunks of my career as a teacher — 1978-83 and 2002-10 — mainly because that is a good way to support travel. At other times I've worked in computing, mostly as a technical writer but a bit of everything else too. My current job is as a technical editor at Shanghai Jiao Tong University, improving the English in papers by Chinese graduate students that are about to be submitted to journals or conferences.

I am quite active on Wikitravel, where I'm an admin, and sometimes contribute to other wikis. See my Wikitravel user page.

I am very interested and involved with computer security and cryptography (see Biography below).

Biography

Academic credentials:

• BA in Psychology from Carleton University, Ottawa, Canada in 1969
• Certificate in Teaching English as a Second Language from Carleton University, Ottawa, Canada in 1977
• Some work toward a Master Philosophy in computational linguistics at the University of Birmingham, United Kingdom, but did not complete that degree.

Publications:

• Key-Dependent S-Box Manipulations, Sandy Harris and Carlisle Adams, Lecture Notes in Computer Science, 1999, Volume 1556/1999, 631-632, DOI: 10.1007/3-540-48892-8_2. This was a peer-reviewed paper and my co-author was an acknowledged expert in the field.
• Exploring Cipherspace: Combining stream ciphers and block ciphers, Sandy Harris, November 2008. On the e-print website of the International Association for Cryptologic Research.

Work and other experience:

• I973 - 1983: Teaching
• 1984 - 2002: Computer industry in Canada
• 2002 - 2010: Teaching.
• Currently working as a technical editor in the Computer Science & Engineering Department at Shanghai Jiaotong University in China , improving the English of papers (mainly by PhD candidates) that will be submitted to international journals or conferences. See here.
• Wrote most of the documentation for the FreeS/WAN project which is a Linux implementation of the IPsec encryption protocols. I have permission to re-use that text here (see User_talk:Sandy_Harris/Permission). I wrote a Citizendium article on FreeS/WAN.
• My Erdös number is five. See The Erdös Number Project for explanation of the Erdös Number Project at Oakland University in Rochester, Michigan.
• My work at Citizendium: Since joining Citizendium in December 2007, I have been the main or only writer of about 58 articles in Citizendium related to computers. See User:Sandy_Harris/Articles for a list of those articles.

I consider myself to be an expert practitioner in the field of computer security and cryptography.
