I am a Ph.D. student in the Robotics Institute (RI) at Carnegie Mellon University (CMU), working with Prof. Shubham Tulsiani. My research focuses on building physics-grounded AI agents, world models, and differentiable simulation. I am currently collaborating with Microsoft on 4D asset generation research. I graduated with a Master of Science in Robotics (MSR) from the Robotics Institute at Carnegie Mellon University where I worked with Prof. Abhinav Gupta and collaborated with Prof. Pedro Morgado at UW-Madison. Before my Master's, I worked as a Research Assistant at CMU with Prof. David Held at the R-Pad Lab, in collaboration with Pittsburgh-based autonomous driving company, Argo AI. During my Masters at CMU, I had worked on self-supervised representation learning methods for multimodal audio-visual videos and as a RA at CMU, I worked on self-supervised algorithms for real-world 3D LiDAR point clouds. I have served in the organizing committee of WiCV@CVPR 2025, WiCV@CVPR 2024, and DEI Social Event@CVPR 2024. I am always looking to collaborate with motivated students on research projects during the semester. If you are interested, please feel free to reach out to me via email. Looking for Spring/Summer 2026 internship opportunities! |

Himangi Mittal, Peiye Zhuang, Hsin-Ying Lee, Shubham Tulsiani [CVPR 2025] Paper / Arxiv / Webpage / Code UniPhy is a unified latent-conditioned neural model which learns a common latent space to encode the properties of diverse materials. At inference, given motion observations for a system with unknown material parameters, UniPhy allows material inference via differentiable simulation latent optimization. |

Himangi Mittal, Nakul Agarwal, Shao-Yuan Lo, Kwonjoon Lee [CVPR 2024] Paper / Arxiv We leverage a large video-language model for anticipating action sequences that are plausible in the real-world. We develop the understanding of plausibility of an action sequence in a large video-language model by introducing two objective functions, a counterfactual-based plausible action sequence learning loss and a long-horizon action repetition loss. |

Himangi Mittal, Pedro Morgado, Unnat Jain, Abhinav Gupta [NeurIPS 2022] ECCV 2022 Workshop on Visual Object-oriented Learning meets Interaction (VOLI): Discovery, Representations, and Applications Sight and Sound Workshop (CVPR 2023) Paper / Arxiv / Code / Video We propose a self-supervised algorithm to learn representations from untrimmed, egocentric videos containing audible interactions. Our method uses the audio signals in two unique ways: (1) to identify moments in time that are conducive to better self-supervised learning and (2) to learn representations that focus on the visual state changes caused by audible interactions. |

Himangi Mittal, Brian Okorn, Arpit Jangid, David Held [BMVC 2021 - Oral (Selection rate 3.3%)] Paper / Arxiv / Code / Conference Presentation / Webpage A self-supervised method to complete the incomplete, partial point clouds for real-world settings like LiDAR where ground truth complete point cloud annotations are unavailable. We achieve this via inpainting where a region of the point cloud is removed and the network is trained to complete this removed region. |

These self-supervised losses allow us to train our method on large unlabeled autonomous driving datasets. |
