I was a ships's Captain for 20 years and then Designated Person Ashore for a ship-owning company in Bremen, Germany until 2 years ago. Both jobs required me to lecture crews in safety and security so I am used to talking to a large group of people of different nationalities including Sri Lankan, Chinese, Filipinos, Burmese, Ukrainians and Japanese. So my niche is shipping. Until about 30 years ago I was a visiting lecturer at nautical schools in my home country of Sri Lanka.
Sri Lanka functions in three languages including English, hence my being English-speaking, having spoken the language growing up at home (in a 'British' kind of environment having been mostly tuned in to the UK), having studied in this medium and having spoken it all my life!
I am also aware of and interested in human relations especially having studied by myself the differences in culture between my home country (where I lived less than half my life having started working on ships travelling worldwide at the age of 17) and that of my present country of residence, Germany. This is because I brought over my wife and grown children and wanted to ensure complete integration here and am aware of cultural differences when dealing with foreigners - a useful trait when teaching foreigners! Incidentally my daughter has worked in Germany for nearly 10 years and son works in the Netherlands - both having completed Masters degrees. My wife works here in Bremen where she lives with me.
I am presently teaching volunteer students online both from Germany and Sri Lanka.
