Currently leading Facebook's AI Editing team, managing a team of mobile/ML engineers putting the latest in ML/CV and LLMs into Facebook's composer and creation tools.Formerly Engineering Manager of Avatars Craft team-- responsible for Asset Pipeline, Metaverse Fashion, and use of GPT-3/Stable Diffusion for Avatar Customization.Formerly Engineering Manager at XR Tech responsible for the audio/CVML technology powering avatar presence in AR-- mobile face tracker, the FACS-based expression tracker, and lipsync.

(Present) Facebook Reality Labs, computer vision and AI features for AR/VR(2019-2020) Instagram AR Platform, launched editorial program for AR effects and built server-side infrastructure for product(2017-2018) Facebook AI Research, engineering manager for fastMRI project(November 2016 - 2017) Facebook Social VR + AI/Computer Vision, launched Facebook Spaces, designed avatar auto-generation algorithms, built and managed the Avatars team(October 2016) "Building 8" Hardware R&D Group, wrote multiplayer social virtual reality applications for use with new hardware prototypes and exploration of computer vision algorithms.(2016) Oculus Computer Vision Team, created VR-based simulations for optimal design of devices tracked by the Constellation Tracking system.(2015) Tech Lead for 'Top Comments' product on public stories, added text embedding-based relevance/quality signals and internal visualization/experimentation system for data-driven ranking system improvement.(2013-2014) News Feed Ranking. Engineered ranking algorithm changes focused on public content feed quality; removing feed spam and identifying high-quality content. Accelerated engineering team iteration speed by building internal web tools for visualization of ranking signals; also built tools for rapid exploration of the News Feed ecosystem.

EM of the FastMRI project at FAIR.Previously was EM of Social VR's avatar team, building a scalable, delightful likeness for users to take into VR spaces.

Working on the Instagram AR Platform, connecting user-made Spark AR filters to the camera-focused social media application, and working with art curator and ranking engineers to surface the best ones.

Computer Vision Team, created VR-based simulations for design of devices tracked by the Constellation system.

Newsle tracks people in the news. As the first hire, I designed and put into production:- High-recall and -precision entity disambiguation system, recognizing people mentioned in newspaper and blog articles by dint of the social, professional, and geographic context. - Industry predictor, automatically annotating the industry and subject of a given body of text.- Low-weight, single-pass news clustering system, linking related articles of the day.- Recommendation system that links a half of a million tracked users by the semantic content of their news clippings, yielding each user's "Related People".- Novel and high-performance public figure disambiguation system based on open-source biographies.

- Developed network visualizations of private company interrelationships from news and patent corpora.- Creating text mining tools and unsupervised learning algorithms for cluster analysis, entity identification, and identifying the semantic structure of a large corpus.- Experimenting with latent semantic indexing and other factorizations (e.g., NMF) to identify principle components of high-dimensional data.- Rapidly prototyped implementations of dense similarity network sparsification, visual edge-bundling, and animations in graph evolution.

Taught an AP Calculus course to a group of highly-motivated secondary students from local schools, with the aim of preparing them to become first-generation college students.

Relating the numerical solutions of stochastic differential equations to partial differential equations.

Systems engineering on Project Constellation.

X-ray crystallography, powder diffraction, superelastic materials. Developed and implemented pattern analysis algorithms of crystalline strain patterns of the superelastic shape-memory material Nitinol, used in cardiovascular implants.
