Phillip HazelPhilip Hazel grew up in South Africa. He has a Ph.D. in applied mathematics and has spent the last 30 years writing general-purpose software for the Computing Service at the University of Cambridge in England. Some major projects were text editors an text formatters for use on an IBM mainframe system. Since moving from the mainframe to Unix around 1990, he has become more and more involved with email. This lead to his developing Exim in 1995 and the PCRE regular expression library two years later. Outside interests include classical music (he is a choral singer and late convert to viola playing), music typsetting, working backstage in amateur theatre, and finding nice places to go walking, preferably not as flat as Cambridgeshire. Philip is married and has three grown sons. Read More Read Less
