About

My interests span a wide range: robotics, perception and spatial computing (computer vision and SLAM), AI research, reinforcement learning, and simulation. I enjoy working across the stack, from low-level systems to learning-based methods, and tying it all back to real hardware. Right now I'm focused on building robots and Ultras.


🤖 Robotics

Autonomous systems, control, and grasp/manipulation

Hardware, control, and simulation for real-world robots — from autonomous platforms to manipulation.

Project Description Stack Link
Subterra Nav Multi-rate EKF fusing IMU, magnetometer, and ToF sensors for 2D localisation of a Mecanum robot. 2nd in cohort at 3.58 cm RMSE. MATLAB, Simulink Repo
IGGY Autonomous quadruped "robot dog" that detects a ball with YOLO and tracks/pursues it through a PID control loop, running onboard in real time. Python, YOLO, OpenCV Repo
Kinesis 6-DoF end-effector tracking for a Franka Panda in MuJoCo: residual RL (PPO) layered on a damped-least-squares Jacobian IK feedforward, robust to observation noise and control delay (0.46 mm RMS). Python, MuJoCo, PyTorch Repo
Dynamic-Gripper-Sim PyBullet grasping simulation that generates data across gripper-object pairs (2/3-finger, arm) and trains ML classifiers to predict grasp success. Python, PyBullet, scikit-learn Repo
SystemsEngineering_IP Stabilised an underactuated physical cart-pole on limited embedded compute; benchmarked LQR, cascaded inner-outer PID, and pole-placement controllers solved offline via the continuous-time Riccati equation and Ackermann's formula. C++, Python, NumPy Repo

Skills: EKF / sensor fusion · PID · LQR · Pole placement · MPC · RL (Residual RL, PPO, GRPO) · Grasp planning · MuJoCo / PyBullet · ROS 2


🛰️ Perception & Spatial

Computer vision, 3D reconstruction, and spatial computing

Turning pixels into 3D — reconstruction, segmentation, and perception for spatial understanding.

Project Description Stack Link
NeMo-Ray 🏆 Winner of NVIDIA Hack for Impact London. Raytracing radio propagations of networks in the city of London using SionnaRT on a 3D digital twin, helping improve the Emergency Services Network (ESN) of the UK. Utilised Nemotron-3-Super and CuOpt to determine the fastest and most efficient way to restoring services in London in case of downed signals. Python, NIM, NextJS Repo
spatiality_v2 Reconstructs 3D scenes from video using a Flash-VGGT backbone paired with a multi-stage segmentation pipeline for clean, properly annotated geometry. Python, PyTorch, VGGT Repo
Innovation Lab Twin Dense 3D digital twin of the UCL robotics lab in Open3D (RGBD registration, pose-graph optimisation, TSDF integration), used as a ground-truth benchmark across 30+ student perception projects. Open3D, Python Private
spatiality Lifts 2D photos into 3D meshes using a standard VGGT reconstruction backbone combined with SAM 3 segmentation. TypeScript, Python, VGGT, SAM 3 Repo
