Curriculum Vitae

I am a postdoc in the Algorithmic Decision Theory (ADT) Group led by Haris Aziz and Toby Walsh at UNSW Sydney. Prior to this, I spent some wonderful time working as a postdoc with Warut Suksompong at the National University of Singapore and completed my PhD at Nanyang Technological University, where I was very fortunate to be advised by Xiaohui Bei.

I am broadly interested in problems at the interface between computer science and economics. Recently, my work has focused on mechanism design and fairness in algorithmic decision-making (e.g., resource allocation, collective choice).
