Miller, a former Scotland Under 20 international, played for Loughborough Students whilst studying Sports Science, and has also captained the side in their National One campaign.
The hooker, who played for Edinburgh at Under 18 level, became an addition to London Scottish's front-row as the squad continued to strengthen their team for the 2017/18 season.
After appearing 17 times in all competitions scoring four times, Miller left the Scots to join Premiership side Worcester Warriors.
He was injured on his debut against Benetton in Treviso in August 2018 and missed the first three months of the season.
Miller made his competitive debut in the European Challenge Cup match in Pau in December 2018 and went on to make five more appearances - all as a replacement - during the season.
He celebrated his first start for Warriors with a try against Leicester Tigers in the opening Premiership Rugby Cup match of the 2019/20 season.
Having made a solid start to his second season at Sixways, Miller signed a two-year contract extension in December 2019.
As of May 2020, he has made 14 appearances for Worcester, and has scored 10 points.
