(https://www.linkedin.com/in/ashley-khoo-856663203)
- Member of NUS ICPC team Strong Zero with IOI gold medallists Yuto Watanabe and Tan Si Jie, coached by Dr Eldon Chung; the team won the 2025 ICPC Asia Yokohama Regional, NUS's first ICPC regional win in Japan, three weeks after also winning the ICPC Taiwan regional. (https://www.comp.nus.edu.sg/news/strong-zero-completes-rare-double-with-nus-first-icpc-regional-win-in-japan/)
- Co-authored the ZeroEntropy paper 'zELO: ELO-inspired Training Method for Rerankers and Embedding Models' (arXiv:2509.12541) with Nicholas Pipitone, Ghita Houir Alami, Advaith Avadhanam and Anton Kaminskyi - the founders and core team of ZeroEntropy. (https://arxiv.org/abs/2509.12541)
- Summer 2025 Research Engineer at ZeroEntropy (YC W25), the AI search/reranker startup; co-founder Ghita Houir Alami announced him as 'the 20 yo 2x Gold IOI medalist who just joined ZeroEntropy (YC W25) for the summer', saying he shipped code on day 1 and proposed new research on day 2.
