Research Interests

Probabilistic modelling and algorithmic design of machine learning for networked and multi-agent systems, inference under bias and privacy constraints.

My current research focus is on privacy in machine learning, and fairness and bias in AI and machine learning.

I have most recently been working on problems related to the following:

Privacy in Machine Learning,
Task classification and expert matching using active learning,
Distributed resource allocation through online learning,
Social Information Networks,
Recommendations under privacy constraints.
