Jargon-busting
Whatever field you explore for your research, you will have terms that others can’t easily understand. There may be terminology that you can’t easily understand. I built up shorthand in my head, “OK, so a genus 2 mutation is like a donut with two holes. But not quite.”
Yeah, not quite…
When you come to read through your thesis, either when you’re finishing it up for submission or when you’re reading to prepare for the viva, make a list of terms that you find. Make notes about what these all mean. Be certain of your jargon. Break it down for yourself and you’ll be able to explain it better to others.
