Profile

Hands-on mechanical engineering work with direct exposure to structures, autonomy, and fabrication.

Marcus Greenan is a mechanical engineering student at the University of California San Diego specializing in robotics and controls. His experience spans aerospace structures, multi-agent robotic systems, autonomous vehicles, and machine shop manufacturing, with a consistent focus on engineering problems that require both analytical rigor and physical validation.

He is strongest in environments where CAD, controls, dynamics, fabrication, and experimental testing have to work together. Across rocket structures, robotics research, and precision manufacturing, he builds systems by iterating from design assumptions to measured performance instead of stopping at theoretical analysis.

Engineering Challenges
  • Balancing structural rigidity with weight constraints so the vehicle remained robust without driving unnecessary mass growth.
  • Maintaining a stable aerodynamic configuration while accounting for drag, stability margin, and mass distribution shifts.
  • Integrating structural components cleanly with propulsion and recovery systems without creating assembly or test bottlenecks.
Validation / Results
  • Supported propulsion and recovery validation with structured instrumentation and data collection during subsystem testing.
  • Compared predicted aerodynamic behavior against measured configuration changes to guide iteration before integration.
  • Established a more defensible structural design process linking CAD, FEA, and aerodynamic analysis.
