Pat Callaghan

Hi! I’m Pat, and I’m a Master’s student in the Robotics Institute at Carnegie Mellon University where I have the good fortune of being co-advised by Professors Henny Admoni and Oliver Kroemer.

Before enrolling at CMU, I worked on the navigation and planning software for MoonRanger under Professors Red Whittaker and David Wettergreen, and I also worked on the CubeRover project's Systems Engineering team. Before robotics, I taught 9th grade Humanities and coached boys' lacrosse and ice hockey at Culver Academies. I earned a dual degree in English and Economics from the University of Virginia.

These days, I'm especially interested in using machine learning and robotic manipulation to improve a robot's efficacy as an individual's long-term personal assistant. In particular, I aim to:

  1. make interactions with a robot as intuitive as possible for people,
  2. use human-provided feedback to improve a robot’s understandings of—and ability to interact with—its human partners and its environment, and
  3. validate our proposed methods through real-world user studies.

We studied how an agent might actively select from multiple forms of human-provided feedback to learn the weights of a human's reward function.

Image and Lidar Dataset of the West Desert Sinkhole: An Analog for Steep-walled Planetary Pits.

We went to the desert and collected data to model the moon's massive pits (which might one day serve as outposts for astronauts).
