Katherine Lee

I’m currently a senior research scientist at Google Brain and a PhD candidate at Cornell advised by David Mimno. My committee includes: James Grimmelmann and Chris De Sa.

Specifically, I study security and privacy in large language models.

I’m broadly interested in the translation between people and the systems we build. What kinds of decisions can algorithms help with, and which should we leave algorithms out of? What kinds of objectives, political or social, can we, or can we not write down?

Before that, I had great fun learning about how real neural networks (brains!) take in the world with Jonathan Pillow and Uri Hasson during my undergrad in Operations Research at Princeton.

You can find me on the internet: Twitter, Google Scholar, Goodreads, or email me at [my github handle]@gmail.com

If you are an undergrad or masters student and interested in memorization and privacy in language models, you can apply to work with me.

I am currently at capacity working with excellent students. You’re welcome to fill out this form, and I’ll reach out when I have more capacity.

Fun!

In my free time, I enjoy making stuff. Sometimes this is pottery, sourdough, or knitting/crocheting. I also enjoy being outdoors, listening to jazz, and dancing. Sometimes all at the same time! I used to live here.

In the more distant past, I’ve also solved for optimal seating arrangements at Google, and I spotted ships at bay with hyperspectral sensors at the Naval Research Lab in DC.
