Welcome!

I am a Research Fellow at Deakin University, Melbourne, VIC, Australia working with Professor Sunil Gupta and Professor Svetha Venkatesh. I earned my PhD in Machine Learning at the prestigious National University of Singapore (NUS), under the great guidance and mentorship of Professor Bryan Kian Hsiang Low and Professor Patrick Jaillet. My research focuses on

  • Bayesian optimization,
  • Active learning,

and other areas such as meta-learning, fairness in collaborative machine learning, machine unlearning, explainable AI, and inverse reinforcement learning.

Currently, I am focusing on devising a general approach that unifies several problems related to Bayesian optimization.


Recently

  • I am thrilled to announce that our work on active set ordering have been accepted for poster presentation at NeurIPS 2024.
  • I am thrilled to share the exciting news that our meta Bayesian optimization and constrained Bayesian optimization have been accepted for poster presentation at ICLR 2024.
  • [Oct 17, 2023 @Phoenix, Arizona] I presented Optimizing Value-at-risk And Conditional Value-at-risk Of Black-box Functions at Bayesian Optimization session at 2023 INFORMS Annual Meeting.
