I am currently a joint postdoc at the Gatsby Unit and at the Hausser lab at University College London. And in December 2014, I will be starting as a group leader at Janelia.

Sebastian Seung supervised my PhD at MIT during which I developed machine learning methods for reconstructing the connectivity of neural circuits from 3d electron microscopic datasets. Led by Winfried Denk, we used these methods to map the connectivity ("contactivity") of the inner plexiform layer of the mouse retina. These methods are also the "AI" that power EyeWire, a citizen-science project led by Sebastian Seung, which uses crowd-sourcing to map a much larger volume of the mouse retina, also imaged by the Denk lab.

My current research lies at the intersection of computational neuroscience and machine learning. I work on on:

  • statistical tools for analyzing large-scale neural recordings
  • models relating neural connectivity to neural activity
  • machine learning algorithms for reconstructing connectomes from electron microscopic images
  • efficient large-scale machine learning algorithms based on deep neural networks and decision trees

I co-organized a workshop at NIPS 2013: Acquiring and analyzing the activity of large neural ensembles.
