Arpit Agarwal
About Me
I am currently an Assistant Professor at the Department of Computer Science and Engineering at IIT Bombay.
Prior to joining IIT Bombay, I was a postdoctoral researcher at FAIR Labs (Meta) working with Max Nickel on socially responsible recommendation systems. Before that I was a postdoctoral fellow at the Data Science Institute at Columbia University
hosted by Prof. Yash Kanoria and Prof. Tim Roughgarden.
I completed my PhD from the Department of Computer & Information Science at University of Pennsylvania, under the guidance of Prof. Shivani Agarwal.
My research lies in the area of machine learning (ML) and artificial intelligence (AI). Specifically, I am interested in the interaction of humans with ML/AI systems. This includes topics in learning from implicit, strategic, and heterogenous human feedback. This also includes understanding the dynamics in the interaction between humans and AI and understanding how one influences the other in the long-term.
Finally, this also includes responsible design of AI systems and understanding/mitigating undesired consequences on individuals and society.
