Mechanical engineer at D-TA Systems. The projects here are my own engineering work outside the day job.
I’m a mechanical engineer at D-TA Systems in Ottawa, where I lead structures and integration on EMSO trailer platforms. The job covers the structures themselves, payload integration, power, thermal management and the mechanical interfaces that tie them together.
I completed my master’s in aerospace engineering at Carleton University, where I focused my coursework on orbital mechanics, space control, space robotics and 3D machine vision. My thesis was experimental: multiphase flow through Venturi aspirators, measured with custom 3D-printed geometries and validated against CFD.
The projects on this site are the space side of that background: spacecraft trajectories, a capture manipulator and a LiDAR reconstruction, modelled from first principles in MATLAB.
MATLAB and STK models of launch, orbital transfer and insertion at the Sun-Earth L1 point, with stability analysis and multi-frame coordinate transformations validating the trajectory across mission phases.
Read the writeup ↗A six-joint arm designed to grapple a fixed point on the derelict ENVISAT satellite and carry it away. Denavit-Hartenberg parameters, a closed-form inverse solution, and a capture path planned through joint space.
Read the writeup ↗A room rebuilt in 3D from 398 hand-collected laser measurements. RANSAC plane fitting, geometric binning and SVD flattening turned a sparse point set into a closed model, checked against a ray-traced virtual room.
Read the writeup ↗An aircraft chosen, an operation designed around it, and the safety case that would let it fly. Three-stage platform selection, a nine-phase concept of operations, and a JARUS SORA assessment taken to SAIL II.
Read the writeup ↗Aircraft requirements derived from a whale survey concept of operations, then three deconflicted waypoint routes and an operational volume sized from a total system error budget.
Read the writeup ↗Two square kilometres of mixed terrain mapped from 100 m above ground. Sensor chosen on pulse rate and field of view, two survey patterns 530 m apart in altitude flown in one sortie, and a SAIL IV case for flying inside a protected park.
Read the writeup ↗Designed and 3D printed custom Venturi geometries with integrated instrumentation, then used dimensional analysis to build analytical performance models from single and multiphase air-water experiments.
Validated the experimental findings against CFD in ANSYS Fluent and OpenFOAM across multiple geometric configurations and operating regimes.
