Welcome to my website! ^ ^ I am a PhD student at the Machine Learning Department of Carnegie Mellon University co-advised by Prof. Pradeep Ravikumar and Prof. Andrej Risteski. My main research focus is understanding discrete "reasoning" tasks. I am also interested in the theoretical understanding of self-supervised and unsupervised learning, often motivated by findings in vision and language. I am also broadly interested in theoretical aspects of machine learning in general.
Previously, I was a master student in the Stanford Vision and Learning Lab, where I worked on video understanding and its applications to healthcare under the supervision of Prof. Fei-Fei Li, Prof. Juan Carlos Niebles, and Prof. Serena Yeung.
Here are some slides from my recent talk which may provide more information about my work.

Paper
Teaching: When at Stanford, I was a teaching assistant for CS231n: Convolutional Neural Networks for Visual Recognition in Spring 2018 and Spring 2019, and the ICU project lead for MED277/CS377: AI-Assisted Healthcare.
I also had a great time working with some talented high school girls who are starting to learn coding. I helped at Girls teach Girls to Code (GTGTC) in April 2018 as the mentor lead of the AI team. I worked with Rob Voigt as research mentors for the NLP team at Stanford AI4ALL in summer 2018, where we worked with an amazing team of 8 girls on a project applying NLP techniques on Tweets to help with identifying resources for disaster relief. If you are interested in learning more about the role identities play in tech industries, please check out the website of Morgan Ames, a postdoc researher who observed the AI4ALL camps and is really nice to talk to. :)
Internship: I joined the Enterprise and Analytics team as a Group IT intern at CLP Power Hong Kong Limited in summer 2016, and was a software engineering intern at Hututa in summer 2015.
