I am a Research Scientist at Google Research, where I lead the Connectomics team.

With partners at HHMI, Max Planck, Harvard, and elsewhere, our team has achieved several milestones in synapse-resolution brain mapping of fly, human, bird, and fish brains, developed Neuroglancer (widely used software for visualizing multidimensional data in the browser) and TensorStore (infrastructure for managing petascale multidimensional data, including checkpoints of nearly all large-scale LLMs trained at Google), produced the first whole vertebrate brain neuron activity prediction benchmark, introduced LICONN with ISTA (the first verified methodology for optical connectomics), and published numerous ML algorithms and advances for interpreting 3d images (including Flood-Filling Networks and SegCLR).

I recently authored a commentary in Nature on how brain mapping and AI can be brought together into digital simulations of nervous systems.

I currently also serve on the Scientific Advisory Council of the Allen Institute for Brain Science and on the Advisory Board for the Chan-Zuckerberg Initiative Imaging program.

From 2011-2013 I was a Laboratory Head at the Howard Hughes Medical Institute (HHMI) Janelia Research Campus. In 2004 completed my undergraduate education at the University of Pennsylvania with degrees in Computer Science and Cognitive Science, followed by a PhD in Computation at MIT.
