Accepted to #CoRL2024: our work on calibrated uncertainty quantification for perception systems for end-to-end statistical assurances for navigation! Perceive with Confidence: arxiv.org/abs/2403.08185 Work led by Anushri Dixit during her postdoc at Princeton University!

Uncertainty quantification is a big missing piece of the puzzle in robotics. Very excited to be organizing a workshop at #RSS2025 with Lars Lindemann and Anastasios Nikolas Angelopoulos! We have a stellar cast of speakers and panelists from academia and industry to discuss the role and

Attending #ICLR2025 next week! I will be presenting Diffusion Policy Policy Optimization (DPPO) at the Friday morning poster session with Lars Ankile diffusion-ppo.github.io I also joined Physical Intelligence lately. Love to chat about what we've been up to at Pi!

What a memorable way to wrap up my PhD: I had the privilege of presenting my work on safe human-centered robotics at the GRASP SFI seminar series Penn Engineering Huge thanks to the GRASP Laboratory for inviting me and to everyone who attended! youtube.com/watch?v=50ZId5β¦
