I started my career in aerospace engineering. While a PhD candidate at Stanford, I studied artificial intelligence and developed neural network architectures for scientific simulations. During the pandemic, I ran a nonprofit to help fight covid with decentralized technology. I care about aligning technology with human rights and values.
There are GPU-accelerated fluid dynamics apps to play with now. I wanted one that allows you to upload your own images as dye ink to create fluid dynamic artwork, so I modified a repository to easily make flowing artwork. Play here. It's free to play and make fluid dynamic art. Works on desktop and mobile. Example artwork on github. github
This is a browser extension that lets you rate any webpage and an associated search engine with confidence scores based on positive and negative valence. I used the same scoring algorithm as reddit's top score plus noise to help elevate new webpages. This is an alternative to click-based models to help combat the excessive rewarding of polarizing content. A paid version could reward content creators to help reduce reliance on ads.

For flutter caused by a transonic shockwave, adding local positive camber to the blade design near the predicted shockwave location is found to eliminate flutter with negligible impact on aerodynamic efficiency.

I was the Executive Director of Covid Watch, a nonprofit I started in February 2020 with a mission to improve the privacy of the contact tracing apps that were being released in response to the pandemic.
We were the first team in the world to publish a white paper, develop, and open source a decentralized exposure notification protocol using Bluetooth communication in March 2020. Within apps that implement the security protocol, data is stored locally on personal devices, and it stays anonymous throughout the notification process. The system is designed to prevent corporations and governments from using the apps for the centralized collection of personally identifiable information. Our TCN Protocol received significant news coverage and was followed by the development of similar privacy-preserving protocols in early April like DP-3T, PACT, and Google/Apple GAEN.
In April 2020, our volunteers and nonprofit staff also released a free and open source mobile app for sending anonymous exposure notifications with development costs funded entirely by prizes and donations. In August 2020, we collaborated with the University of Arizona on research to improve the estimation of infection risk from anonymous Bluetooth data to better inform private quarantine recommendations.

I originally worked in aerospace engineering, completing my M.S. at the University of Arizona. While at Honeywell Aerospace, I invented and patented a method for reducing the risk of transonic flutter in turbomachinery, improving the safety of next generation jet engines. After spending several years in industry, I decided to pursue a PhD at Stanford supported by a Department of Energy Computational Science Graduate Fellowship (DOE CSGF).
At Stanford, I've focused on courses in computer science and machine learning. I developed two novel methods for faster and more accurate reduced order models and I designed neural network architectures for approximating the solutions to partial differential equations by breaking them into parts. My long term research goal is to interpret and understand how to automatically draw boundaries in data in a way that is useful for prediction and explanation.
