About
I am a Senior Applied Scientist at AWS AI Labs, where I develop research that powers the next generation of multimodal foundation models. Check out a couple recent examples here and here. Earlier this year, we launched Titan Image Generator, Amazon’s first text-to-image foundation model! Before this, I developed the NLP that powers Amazon’s physical store for clothing, Amazon Style. I received my PhD from Stanford University under the supervision of Johan Ugander, where I focused on designing and analyzing algorithms for preference learning from human feedback. My work commonly falls at the intersection of Natural Language Processing, Computer Vision, and Preference Learning.
I interned at Facebook CDS in the Summer of 2020, and helped develop ways to use People You May Know (PYMK) to catch spammers. In the Summer of 2019, I interned at Stitch Fix where I helped develop numerous approaches to better understand Client and Stylist preferences. Before my graduate work I received a BS in Electrical Engineering, Mathematics, and Economics from the University of Wisconsin, where I was advised by Barry Van Veen and Robert Blick. I have also interned at a number of companies in the past, including Microsoft and Silicon Labs.
