Northwestern University · Mechanical Engineering BS/MS · Aerospace Concentration

Rodrigo
Diaz

Pursuing a combined bachelor's and master's in Mechanical Engineering at Northwestern with an Aerospace Concentration. My work spans CFD and aerodynamics, structural and machine design, dynamics and vibrations, and hands-on manufacturing — from transient F1 wing CFD and Mars rover descent optimization to in-house fiberglass rocket airframes and a gearbox sized down to the last bearing.

About

Engineering from first principles to physical artifact.

I'm pursuing a combined BS/MS in Mechanical Engineering at Northwestern University with an Aerospace Concentration. My work spans the full engineering arc — from constrained optimization and CFD to composite layup in a lab, from FEA validation in ANSYS to physical testing under realistic loading conditions.

I conduct undergraduate research in Professor Tao Sun's FAST-AM Lab, investigating vibration-assisted wire-laser directed energy deposition of Inconel 718. Outside of research, I build and fly high-power rockets with NUStars and serve as Academic Affairs Coordinator for Delta Tau Delta.
