Welcome to the Complex Engineering Systems Lab at Stevens!

The research in the Complex Engineering Systems Lab, directed by Prof. Hao Chen, is in the areas of space systems and complex system design. Our research program mainly focuses on high-level space system development to significantly improve space mission affordability, comfortability, and reliability. Three main research thrusts of our lab are,

Thrust I: Space Systems Design:

  • Key research areas:
    • Space logistics
    • Space resource utilization
    • Multi-mission space campaign design
    • On-orbit servicing, assembly, and manufacturing (OSAM)
  • Main application goal:
    • make space mission affordable

Thrust II: Space Health:

  • Key research areas:
    • Human factors and behavioral performance in space
    • Spacesuit systems
  • Main application goal:
    • make space mission comfortable

Thrust III: Complex Systems:

  • Key research areas:
    • Engineering design in extreme environments or at extreme scales
  • Main application goal:
    • make space mission reliable

Fully funded Ph.D. student positions for Fall 2023 are available in my lab, with a particular focus on research in Systems Engineering and Engineering Design.
