I have a wealth of experience as a journalist working in Switzerland and enjoy producing videos, articles and podcasts on a range of subjects, recently focused mainly on politics and the environment. Born in the UK, I studied law at Nottingham University, then went on to attend the first-ever post-graduate radio journalism college in London. After working as a radio journalist in the UK and then Switzerland from 1984 to 1995, I returned to the UK to complete a post-graduate diploma in film at Bournemouth Film School. I have been working as a video journalist ever since.
