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 in Python 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 Additive Manufacturing Lab, investigating vibration-assisted wire-laser directed energy deposition of Inconel 718. Outside of research, I build rockets with NUStars and serve as Academic Affairs Coordinator for Delta Tau Delta.
