🔬 I am a Scientist at A*STAR's Centre for Frontier AI Research (CFAR). My research is centered on rigorously analyzing the theoretical underpinnings of decision-making in multi-agent systems. I aim to elucidate how these theoretical insights can inform and improve practical applications, with a particular focus on collaborative, distributed, and federated reinforcement learning.

🏫 I obtained my PhD in the Department of Computer Science at the National University of Singapore (NUS), sponsored by the Agency for Science, Technology and Research (A*STAR) under its A*STAR Computing and Information Science Scholarship (ACIS). I am honored to receive supervision from Prof. Wei Tsang Ooi from NUS, Dr. Cheston Tan from A*STAR, and Prof. Roger Wattenhofer from the Swiss Federal lnstitute of Technology Zurich (ETH Zurich).

📧 I will soon start postdoc research at ETH Zurich, focusing on distributed computing for machine learning, mainly reinforcement learning (RL) and large language models (LLMs). I am actively looking for students to collaborate with. If you...

• want to know more about postgraduate programs at NUS,
• are looking for research project/thesis offering at ETH Zurich (mostly for D-ITET and D-INFK students),
• want to apply for the various research opportunities and scholarships at A*STAR,

please do not hesitate to contact me! 📧
