Convincing Robots to Trust Humans

Jan 2020- UC Davis
Graduate Student Researcher

As humans wade further from Earth, we must develop technologies to support our survival. The Habitats Optimized for Missions of Exploration (HOME) research institute develops a basic understanding of how habitats interact with humans using mixed autonomy. Robotic systems must collaborate with humans when necessary and maintain themselves when humans are away. I’m studying high-level robotic decision-making in collaborative tasks. See the Education section below for more information about my research.

Professional Training

May 2023-Aug 2023 NASA Science Mission Design School
Planetary Science Summer School

With a team of early career scientists and engineers, I developed a conceptual mission to Neptune’s moon, Triton. Planetary Science Summer School is an 11-week program including rigorous preparation for a final week of concurrent mission design with NASA Jet Propulsion Lab’s Team-X. In this experience, I served as Project Manager and organized teamwork, mission requirements, and spacecraft capabilities. Our mission aimed to characterize the subsurface ocean of Triton, the enigmatic surface plumes, and unique cantaloupe terrain. Look out for our poster presentation at the American Geophysical Union Fall Meeting 2023.

Experience

In addition to the professional experience listed below, you can find my infinitely expanding hobby, Open Source, and self-teaching projects on Github. I have a habit of dreaming about an end product and learning the skills needed to produce it, whether or not those skills are in my wheelhouse. So I’m hoping that the software I share can improve community-driven projects and that snippets of my half-finished thoughts can help other learners.

Aug 2021-June 2022 NASA Ames Research Center
Intern Intelligent Robotics Group

Distant robotic systems operate under significant time delay, posing teleoperation challenges for earthly operators. Predictive systems could fill the temporal void between commands sent to a robotic system. Still, proposed techniques rely on precisely modeled systems. In this project, I’m studying the performance of a human-astrobee team operating under time delay with an idealized predictive system.
