Biography
Alexander's background includes extensive experience in employing hybrid machine-learning and model-based approaches towards planning, control, and estimation in both simulation and hardware including legged, climbing, wheeled, and flying robots. His Ph.D work covers topics such as reinforcement learning, Active SLAM, stochastic model predictive control, force control for manipulation and grasping, and estimation using filtering methods combined with vision transformers and deep learning techniques. His current research interests focus on advancing learning methods, from traditional neural networks to large language models, through embedded
knowledge of the underlying physics of the environment, robots, and contacts between them. -

CA0129: Internship - LLM-guided Active SLAM for Mobile Robots
MERL is seeking interns passionate about robotics to contribute to the development of an Active Simultaneous Localization and Mapping (Active SLAM) framework guided by Large Language Models (LLM). The core objective is to achieve autonomous behavior for mobile robots. The methods will be implemented and evaluated in high performance simulators and (time-permitting) in actual robotic platforms, such as legged and wheeled robots. The expectation at the end of the internship is a publication at a top-tier robotic or computer vision conference and/or journal.
The internship has a flexible start date (Spring/Summer 2025), with a duration of 3-6 months depending on agreed scope and intermediate progress.
Required Specific Experience
- Current/Past Enrollment in a PhD Program in Computer Engineering, Computer Science, Electrical Engineering, Mechanical Engineering, or related field
- Experience with employing and fine-tuning LLM and/or Visual Language Models (VLM) for high-level context-aware planning and navigation
- 2+ years experience with 3D computer vision (e.g., point cloud, voxels, camera pose estimation) and mapping, filter-based methods (e.g., EKF), and in at least some of: motion planning algorithms, factor graphs, control, and optimization
- Excellent programming skills in Python and/or C/C++, with prior knowledge in ROS2 and high-fidelity simulators such as Gazebo, Isaac Lab, and/or Mujoco
Additional Desired Experience
- Prior experience with implementation and/or development of SLAM algorithms on robotic hardware, including acquisition, processing, and fusion of multimodal sensor data such as proprioceptive and exteroceptive sensors
