Introduction

In episode 54 of The Gradient Podcast, Andrey Kurenkov speaks with Pete Florence.

Note: this was recorded 2 months ago. Andrey should be getting back to putting out some episodes next year.

Pete Florence is a Research Scientist at Google Research on the Robotics at Google team inside Brain Team in Google Research. His research focuses on topics in robotics, computer vision, and natural language -- including 3D learning, self-supervised learning, and policy learning in robotics. Before Google, he finished his PhD in Computer Science at MIT with Russ Tedrake.
