Alejandro Turnbull — I build things that leave the ground.

Composite airframes on an award-winning liquid bipropellant vehicle. Scratch-built avionics that talk to the ground. One rocket that came apart just short of burnout and taught me more than the ones that worked.

About Me

I'm a third-year physics student at UC Riverside and president of the Highlander Space Program, our university rocketry team.

I'm fascinated by our world and by using science and technology to make it a better place — and to better understand our little planet's place in the universe. Engineering has provided a tremendous service to humanity, and I'm always looking for ways to be part of that proud history: pushing the limits of what's possible, and bringing frontier technology down to earth to help everyday people.

On the rocket team I've done hands-on composite fabrication, structural design, and launch operations for our award-winning liquid-fueled rocket. On my own time, I design, build, and fly high-power vehicles with scratch-built avionics. Whenever I'm not building, I'm writing: covering the space industry for Space Scout, including credentialed coverage of Artemis II from NASA's Johnson Space Center.

Selected Work

08 ENTRIES
Poseidon liquid rocket igniting on the pad
Liquid Bipropellant Flown · 2 Awards

Poseidon

UC Riverside's award-winning first liquid-fueled rocket. I built composite airframe structures, designed and manufactured the rail guides, and worked the championship-winning launch campaign at FAR-OUT — first in its altitude category and the most efficient liquid in the competition.

TANGERINE firing on its vertical test stand in the desert
Liquid Bipropellant · Subscale In Development

TANGERINE

A subscale liquid test rocket I lead — the stepping stone from Poseidon to our next-generation Clementine, flight-proving engine integration, novel recovery, and payload deployment. Cold flows complete; static fire campaign underway.

The liquid argon condenser under assembly: steel tanks in a t-slot frame with a blue valve panel
Detector Physics · Cryogenics Active Research

DarkSide-20k

In the Westerdale Lab, I build hardware for the liquid argon condenser supporting DarkSide-20k's hunt for dark matter — including sensor probes that live inside the cryogenics for real-time monitoring at 87 kelvin.

Photon solid rocket leaping off the launch rail
Solid / Avionics 3 Flights · Active

Photon

A scratch-built solid rocket packing Level-3 capability into a Level-1 budget: redundant dual-deploy recovery and a custom GPS telemetry link to a scratch-designed ground station.

Supersonic Attempt Lost — In-Flight Breakup

Muon

Built to break the sound barrier; broke itself instead. A dramatic structural failure at near-max speed — and a masterclass in failure analysis, resilience, and designing margins.

Medical Robotics Research · UC Irvine

AirSTEP

A novel biomechatronic device under development at UC Irvine to promote gait recovery in spinal cord injury patients. I designed and built new patient-feedback hardware in response to clinical trials.

Leadership & Outreach Ongoing

The Human Element

Rockets are a team sport. From historical interpretation at Philmont Scout Ranch to knocking thousands of doors for a congressional campaign, I've built the communication and leadership skills that make hard engineering possible.
