I am an incoming Assistant Professor of Interactive Computing at Georgia Tech starting in Fall 2026. My research focuses on robotics, multimodal machine learning, and human-robot interaction across two axes:
Join my Lab! I am recruiting multiple PhD students to join my lab at Georgia Tech starting in Fall 2026. Please apply to the PhD Program through the School of Interactive Computing (in Robotics, Machine Learning, or Computer Science) and list me as a potential advisor! Feel free to shoot me an email with any questions. |

[May 2025]: I am thrilled to be joining Georgia Tech as an Assistant Professor of Interactive Computing starting in Fall 2026! I'm honored to be joining an amazing group of faculty and students, and building a new lab to work at the intersection of robotics, machine learning, and human-robot interaction.

[November 2024]: Looking forward to being at CoRL 2024 presenting both Vocal Sandbox and OpenVLA; don't miss Jenn's talk on Vocal Sandbox during Oral Session 3! I'll also be at the afternoon panel at the LangRob workshop on Saturday – hope to see y'all in Munich!
-
[October 2024]: Excited to share "Vocal Sandbox: Continual Learning and Adaptation for Situated Human-Robot Collaboration" – we introduce a new framework for building robots that can progressively improve over time, learning new skills, visual concepts, and planning behaviors from their partners in real time. Check out our project page for videos, especially our two hour long demo deploying a Vocal Sandbox system for LEGO stop-motion animation!
-
[June 2024]: Introducing "OpenVLA: an Open-Source Vision-Language-Action Model" – a generalist policy for robotic manipulation, built directly using the VLMs/codebase we developed in Prismatic. Trained on almost 1M demonstrations from Open X-Embodiment (and DROID), not only do we get some great zero-shot performance, but you can efficiently fine-tune for new robots and tasks! Huge shout out to my co-leads Moo Jin Kim and Karl Pertsch; check out our models on HuggingFace, and our codebase.
