There he was eliminated in the semifinals of the 100m butterfly, and finished in fourth place with the men's 4×100 medley relay team. A year earlier, Keizer won the bronze medal in the 50m butterfly at the [[1999 FINA Short Course World Championships]]. He retired from the sport after a disappointing appearance at the [[2004 Summer Olympics]] in [[Athens]], [[Greece]].

He received his PhD in Physics and is now a Associate Professor at the [[University of New South Wales]].<ref>{{Cite web |title=Associate Professor Joris Keizer |url=https://www.unsw.edu.au/staff/joris-keizer |access-date=2025-06-10 |website=UNSW Sites |language=en}}</ref> He has gone on to do research into the fields of [[quantum computing]] and [[quantum physics]] at [[Silicon Quantum Computing]].<ref>{{Cite journal|last1=He|first1=Y.|last2=Gorman|first2=S.
