Lam Lay Yong

Lam Lay Yong also won the 2005 Outstanding Science Alumni Award from NUS.

[5] Lam Lay Yong has hypothesised that Hindu–Arabic numeral system originated in China.

One was from mathematician's mention, for example a critique of Severus Sebokht on Indian ingenuity, and Al-Khwarizmi's book on Hindu Calculation.

[7] However Michel Danino criticised this by saying that Lam Lay Yong's evidence for this was not evidence-based nor rigorous, and that she is ill-qualified for cross-cultural studies.

All of this seems to contradict Yong's claims that there is strong evidence of rod numerals in India.
