I am a Senior Staff Machine Learning Scientist at Tesla Autopilot where I train production neural networks for Tesla's ~5M customers. I lead the team of engineers and scientists that build Autopilot's foundation models. I like working across a wide range dimensions - data, architecture, optimization, evaluation, deployment, latency - to achieve the maximum possible impact in the real world.
Previously I worked at Google Brain developing recurrent architectures that trade off latency and performance in segmentation tasks, and completed my PhD at Stanford in theoretical neuroscience and computer science.
Training production neural networks for Tesla's active safety and full self driving products.

A central challenge in sensory neuroscience is to understand neural computations and circuit mechanisms that underlie the encoding of ethologically relevant, natural stimuli. In neural circuits, ubiquitous nonlinear processes present a significant obstacle to the creation of accurate computational models of responses to natural stimuli. We demonstrate that deep convolutional neural networks capture retinal responses to natural scenes nearly to within the variability of a cell's response, and are markedly more accurate than previous models. We are then able to probe the learned models to gain insights about the retina, for instance how it compresses natural scenes efficiently through feedforward inhibition and how it transforms potentially large sources of extrinsic and intrinsic noise into sub-Poisson variability. Overall, this work demonstrates that CNNs not only accurately capture sensory circuit responses to natural scenes, but also can yield information about the circuit's internal structure and function.

Stanford MBC talk IEEE talkRetinal ganglion cells, the bottleneck of all visual information to the brain, have linear
response properties that appear to maximize information between the visual world and
the retinal ganglion cell responses, subject to a variance constraint. In this paper I contribute
a new theoretical finding that generating the ganglion cells' linear receptive field from
inhibitory interneurons with disparate spatial scales provides a basis that allows the receptive
field to maximize information under a wide range of environments whose signal-to-noise
ratios vary by orders of magnitude.

How can we automatically extract events from video? We used a database of surveillance videos and examined the performance of SVMs and Convolutional Neural Networks in detecting events like people getting in and out of cars.

How should an intelligent system intent on only keeping information predictive about the future filter its data? We analytically find the optimal predictive filter for Gaussian input using recent theorems from the information bottleneck literature. Using numerical methods, we then show the resemblance of these optimally predictive filters to the receptive fields in early visual pathways of vertebrates.

Recent theorems in nonequlibrium thermodynamics show that information processing inefficiency provides a lower bound for energy dissipation in certain systems. We extend these results to model neurons and find that adapting neurons that match the timescale of their inputs perform predictive inference while minimizing energy inefficiency.
