Balvinder Singh

Despite his first-class undergraduate degree in Mathematics, Balvinder ("Bal") Singh is still a massive disappointment to his family, because by this point in his life he should have qualified as a doctor, settled down and started a family with a nice Punjabi girl. Instead, he has chosen to study for a PhD in Mathematical Biology, which isn't even a real thing as far as they are concerned. His supervisor is Patrice Ambrose, via whose partner Ali he has obtained an internship at Dot Chan.

If his parents knew that his hobby was lock-picking, they would probably refuse to ever speak to him again.
