OASIS: A Large-Scale Dataset for Single-Image 3D in the Wild

Lack of high-quality, diverse, and large-scale data impedes research in many fields, including single-image 3D vision. For my senior thesis, I helped create OASIS, a large-scale dataset for single-image 3D in the wild. I implemented a pipeline for crowdsourcing dense pixel-wise 3D ground truths from sparse annotations, and quality control mechanisms to ensure annotation consistency.

I also trained state-of-art deep learning models to benchmark OASIS for monocular surface normal estimation and planar semantic segmentation, and evaluate cross-dataset generalization. I provided the baseline for fold and occlusion boundary detection. The dataset improves performance in multiple visual tasks, and also introduces new tasks for research.

This work was accepted to CVPR 2020 and advised by Professor Jia Deng.

TigerTexts | Spring 2018

Finding coursebook info for Princeton students is unnecessarily difficult. I built a web app that consolidates Princeton coursebook pricing from multiple sources, and offers third-party seller options, thus providing the most complete information on cheap textbooks. Built in Express.js, React, Redux, Python, and MongoDB.

Lyff | PennApps Fall 2017

We built a voice bot that users can call to order a Lyft ride. This is useful where Internet and/or cellular data is inaccesible (which can happen even in urban areas, from personal experience). We won the “Best use of Vonage/Nexmo API” prize. The following APIs were used: Nexmo for the voice bot, Amazon Lex/Lambda for voice processing and parsing, Google Maps API to sanitize locations, Lyft API for making Lyft calls. Press received:

Princeton University Science Olympiad

Princeton University Science Olympiad | Fall 2016

In Fall 2016, I co-founded a tournament that hosts 800 high school students from around the nation each year. I led a team of 8 undergrad students and 120 volunteers in the execution of 23 competition events, and raised a budget of $10,000. In 2017, we became the first college-run tournament nationwide to waive registration fees. I developed the static website in HTML/CSS/Javascript. We have received the following press:
1. Scientific American
2. Princeton University


HackPrinceton | Fall 2016 - Spring 2018

HackPrinceton is Princeton’s biannual student-run hackathon which hosts 1,100 students per year. As co-director From Fall 2017-Spring 2018, I led a team of 30 undergraduate organizers and combined budget of $150,000. From Fall 2016-Spring 2017, I was an organizer and coordinated bus routes, workshops, prizes, and mentorship. Below is a sample of the press we have received:
1. Business Insider
2. Princeton School of Engineering
3. Princeton Entreneurship Council


UBiT2 | Summer 2016

I worked with Dr. Jean Fan to develop an open-source web application for client-side RNA-seq and qPCR data analysis. All computation and data visualization is done client-side, thus providing a secure and fast environment for bioinformatics that involves no server. Built in HTML, CSS, and Javascript.

Claims-Wide Association Study | Summer 2016

I worked with Prof. Isaac Kohane and Dr. Arjun Manrai to develope a new association study called “claims-wide association study (CWAS)” - like genome-wide association studies (GWAS), but for insurance claims. I built a data visualization tool for plotting heatmaps of the USA from parsed AETNA insurance claims, at multiple levels of geographic specificity (zipcode, county, state, regional). Built in R, MySQL, and the Shiny web framework.
