About:

I am a Postdoctoral Fellow hosted by Toby Walsh, at the School of CS & Eng at UNSW Sydney. 

Prior to joining UNSW, I finished my PhD in computer science at McGill University under the supervision of Adrian Vetta. 

Research Interests:

My research interests lie at the interface between AI, theoretical computer science, and economics. In particular, my recent research has been focused on fair division and social choice. Broadly, I am interested theoretical computer science and its applications.

• I visited Gerardo Berbeglia and Matthew Tam at Uni Melbourne and gave a talk at OPTIMA seminar

• Two papers accepted at AAAI 2024!

• I will be giving a tutorial at WINE 2023 on mixed fair division
