PhD Candidate, Electrical Engineering
CRISP Group, Harvard University

I received B.ASc. degree with distinction in Electrical Engineering from the University of Waterloo in 2017. I am currently a PhD Candidate, advised by Demba Ba, at Harvard University.

I spent summer 2019 at Amazon AI as an Applied Scientist Intern working on neural architectures for multichannel speech enhancement. I will be joining the Applied Sciences Group at Microsoft as a Research Intern for summer 2021.


My research interests are at the intersection of deep learning, statistical signal processing, and computational neuroscience. My PhD research is divided into three tracks:

  • model-based deep learning: I develop networks using probabilistic generative models and dictionary learning, applied to inverse problems such as compressive sensing and denoising.
  • deep learning theory: I develop theory for gradient dynamics and implicit acceleration.
  • computational neuroscience: I develop algorithms for a variety of problems such as neural encoding in the olfactory system and spike sorting.
