About me
Hey, I’m Alex. I work at Nvidia on real‑time 3D reconstruction for robotics using embedded GPUs.
I finished my Ph.D. at the Autonomous Systems Lab at ETH Zürich, in Switzerland in 2021. My research focused on 3D map-building for rotary-wing UAVs, and more generally on mapping large-scale environments on computationally constrained platforms. I spent the final part of my Ph.D. as a visiting scientist in the Microsoft Mixed Reality & AI Zurich Lab.
Prior to my Ph.D., I wrote state estimation and machine learning algorithms for a Formula-1 team, and spent time prior to that, developing acoustic devices which I helped install in heavy machinery. I finished a Masters’s in Robotics, Systems, and Control in 2015, also at ETH, and I hold a Bachelor’s degree from Canterbury University, located in Christchurch, New Zealand, where I grew up.
I love working with passionate people on hard problems that lie in the intersection of mathematics, software, and physical systems
Work at Nvidia
nvblox: GPU accelerated real-time reconstruction for robotics
We’re working to bring real-time reconstruction and vision-based navigation to future robots by leveraging Nvidia Jetson devices. Our work is open-source (nvblox), and ready for use with ROS2 (nvblox_ros). This work was featured in a video at GTC 2022.

Projects
Autonomous Fire-Fighting
In this project we built a system for autonomously finding fires in multi-story buildings as part of our entry to the MBZIRC 2020 international robotics competition. The mission is completed by a collaborating robotic team, consisting of a hexacopter and a tricopter. The approach exploits the mapping and precise control capabilities of each of the vehicles respectively. If you’re interested, check out our video.
Thermal Mapping
In this work we showed a UAV building dense 3D maps, localizing within these maps, and autonomously navigating through narrow spaces to find potential injured people using a thermal camera. We demonstrated this at a search and rescue training site in Switzerland. If you’re interested, check out our video.
