He discovered a passion for engineering research during his undergraduate days at Nanyang Technological University.
And now, he is pushing himself further by pursuing a PhD in material science at his alma mater.
Ang, who is on a scholarship, acknowledged that Singapore is a "paper-chasing country" and that having an extra feather in his cap will be an advantage.
"I've worked hard to get to where I am today. It didn't all just fall into my lap. I realised I had a passion for research so I decided to come back and pursue it," he said.
"Not many Singaporeans want to pursue a PhD. Most of the time, it's foreign scholars coming in. If I want to remain in research, a bachelor's qualification is not enough."
But it's not all work and no play.
Ang, who is single and has been living in Hougang for the last 16 years with his parents, said: "Mr Singapore is an opportunity to do what I like, from modelling to photoshoots to travelling.
"But it's definitely not a full-time thing. I mean, how long can my youth last?
"For me, it's like my CCA (co-curricular activity)."
