Josue Torres-Fonseca (he/him)

Hi! I am a PhD candidate at the University of Michigan, Department of Computer Science and Engineering. I work with Dr. Joyce Chai as a member of the Situated Language and Embodied Dialogue (SLED) Lab. My research focuses on language understanding, cognitive development, and embodied agents, specifically, how robots can take advantage of their ability to interact with the world around them to learn language during spoken interaction with others. Prior to joining the University of Michigan, I graduated from Boise State University with a B.S. in Computer Science (Magna Cum Laude, Minor in Applied Mathematics), where during my last two years I performed research advised by Dr. Casey Kennington as a member of the Speech Language and Interactive Machines (SLIM) Lab.

History of academic appointments.

Computer Science and Engineering Division, University of Michigan
August 2023 - Present

PhD Candidate, Situated Language and Embodied Dialogue Group

Supervised by Dr. Joyce Chai. Created a safety-centric dataset using PDDL to generate trajectories demonstrating how to complete household tasks while mitigating hazards rendered in the AI2-Thor simulator. Evaluated 11 state-of-the-art VLMs on hazard recognition via Visual Question Answering (VQA) and safe plan generation as an embodied agent performing household tasks while proactively mitigating hazards. Developed a decoupled multi-agent framework that separated hazard recognition from task execution, resulting in increased safety-planning success rates.

Ann Arbor, MI, USA
Department of Electrical Engineering and Computer Science, MIT
May 2022 - November 2022

Undergraduate Researcher, Language & Intelligence Group

Supervised by Dr. Jacob Andreas. Designed and built an interpretable ML model providing neuron annotations using no data. Presented poster at the MIT Summer Research Program poster session and delivered a lightning talk on the MIT Grad Diversity YouTube channel.

Cambridge, MA, USA
Department of Computer Science, Boise State University
August 2021 - August 2023

Undergraduate Researcher, Speech Language and Interactive Machines Group

Supervised by Dr. Casey Kennington. Designed and built an incremental spoken dialogue system capable of transcribing and understanding speech, detecting and gaining a concrete understanding of objects, and mapping objects in its environment using SLAM and the Anki Cozmo robot.
