Design, Implementation, and Validation of a State Estimator for the MoonRanger Lunar Rover
Abstract: The MoonRanger Lunar rover will demonstrate continuous, on-board, long-range autonomous navigation at the Moon's South Pole. In this thesis, I describe how MoonRanger estimates its position and orientation using input from several sensors: Inertial Measurement Unit (IMU), Sun Sensor, wheel encoders, and cameras. I thoroughly review the state estimation approaches for prior space rovers [...]
Towards Scalable Real2Sim and Evaluations for VLAs
Abstract: The evaluation of generalist robot policies, particularly Vision-Language-Action (VLA) models, is limited by the cost and scalability of real-world testing. This thesis introduces RobotArena ∞, a scalable benchmarking framework for large-scale simulation-based evaluation. Central to RobotArena ∞ is a fully automated reality-to-simulation (Real2Sim) pipeline that converts monocular video demonstrations from datasets such as Bridge, [...]

Creative and Reliable Exploration in Language Model Reasoning
Abstract: Language models increasingly solve hard problems by exploring multiple reasoning paths at training and test time. But making this exploration effective requires balancing two goals that are often in tension: creativity and reliability. On the one hand, models need to generate diverse, non-myopic reasoning strategies rather than repeatedly sampling the same mistakes. On the [...]
Unified Spherical Frontend: Towards Universal Distortion-Free Lens-Agnostic Rotation-Equivariant PerceptionUnified Spherical Frontend: Towards Universal Distortion-Free Lens-Agnostic Rotation-Equivariant Perception
Abstract: Modern perception increasingly relies on wide field-of-view cameras, yet standard convolutional networks still operate on planar pixel grids designed for pinhole imagery. By Gauss's Theorema Egregium, no projection from the sphere to the plane preserves curvature, so every planar map of a spherical signal introduces spatially-varying distortion. Models trained on one lens therefore overfit [...]
Synthetic Data for Object Detection: Improving Robustness and Revealing Vulnerabilities
Abstract: Synthetic data has emerged as a promising solution to the growing challenges of data acquisition in object detection. Modern detectors rely heavily on large-scale annotated datasets, yet collecting real-world data with high-quality labels is often costly, labor-intensive, and impractical in diverse or rare scenarios. By enabling controllable generation with automatic annotations, synthetic data provides [...]

Precise and Generalizable Robot Manipulation
Abstract: Robots in factories are still largely limited to structured environments with known object models. How can we bring robots into the more diverse, unstructured settings of our daily lives, where objects may vary widely in shape and appearance, while maintaining reliable performance? A popular direction today is to train generalist robot policies on large-scale internet [...]
