I am a roboticist and computer scientist.

Currently, I am with the NASA Ames Intelligent Robotics Group, where I've helped make Astrobee fly autonomously inside the International Space Station. I also lead a project to automatically map floods from satellite imagery for disaster response. I've contributed to multiple open source releases: Astrobee, ISAAC, DELTA, and Crisis Mapping Toolkit.

Previously, I was a Ph.D. student in the Robotics Institute at Carnegie Mellon University, where I was advised by Manuela Veloso. While there I worked on the CoBot robots, which have traveled over a thousand miles autonomously, performing tasks for users in a multi-story office building. My Ph.D. thesis focused on scheduling these robots to perform pickup and delivery tasks, with transferring items between robots. At CMU, I also competed at RoboCup soccer in the Standard Platform League with the NAO robots.

My research interests include planning and scheduling, multi-robot systems, localization, computer vision, path planning, machine learning, Earth science, and more. I also enjoy backpacking and climbing mountains.
