About me

My research is centered around the pursuit of intelligent systems that are flexible and adaptable. I'm currently excited about:

  • Building systems that can effectively ingest large amounts of diverse data towards the goal of solving new learning tasks from unseen datasets or domains. We recently created the Meta-Dataset benchmark to facilitate research in this direction.
  • Understanding the nature of representations that enable few-shot learning. What is the role of meta-learning / episodic training towards that goal?
    • We studied a more challenging context-dependent variant of few-shot classification, and discovered that unsupervised learning is crucial for that problem.
    • Our ongoing work investigates the role of the episodic training paradigm through the lens of shot-specialization.

I also enjoy food blogging, dance (recently hip hop and contemporary), piano playing, singing and song writing.

I am graduating in the summer of 2021 and on the job market for research scientist or postdoc positions.
