James Steen's parents have paid tribute to their "darling son."
"Words simply can not convey the pain we are currently experiencing," they said.
"James enriched our lives, and the lives of others, in so many ways. He was a kind, caring, intelligent and very talented young man, with a generous spirit. He touched everyone he met with his positivity and his sense of humour.
"He loved life. We are devastated by James' untimely death, but we are comforted by knowing how much he was loved and admired by his family, friends and university colleagues," they added.
"We are immensely proud of our son, and all he achieved and the significant mark he made during his brief time on this earth."'Impressive academic ability'
