I am a PhD student in the Stanford Vision Lab, advised by Professor Fei-Fei Li .
I'm mainly interested in deep learning, especially applied to computer vision.

A Torch implementation of the neural style transfer algorithm from the paper "A Neural Algorithm of Artistic Style" by Leon A. Gatys, Alexander S. Ecker, and Matthias Bethge.


A tool to use convolutional neural networks to generate images, inspired by Google's Inceptionism.


Train character-level language models in torch, and sample from them to generate text. The language model is implemented with efficient, reusable RNN and LSTM modules.


A micro-framework I built to make it easier to create and launch tasks on Amazon's Mechanical Turk.


Benchmarks for popular convolutional neural network models on different GPUs.


Winter 2015-2016:

I am co-teaching CS 231n: Convolutional Neural Networks for Visual Recognition.

Winter 2014-2015:

I was a teaching assistant for CS 231n: Convolutional Neural Networks for Visual Recognition.

Fall 2013-2014:

I was a teaching assistant for CS 131: Computer Vision: Foundations and Applications.
This was an undergrad-level course intended to introduce the basics of computer vision.
