The Space Systems Optimization Laboratory focuses on development of mathematical theories and their application to rigorous space mission analysis, design, and optimization.

We have theoretical expertise in:

  • Mathematical Optimization Techniques including Linear/Nonlinear Programming;
  • Probabilistic Modeling and Simulations;
  • Heuristics Optimization Techniques including Genetic Algorithms and Simulated Annealing;
  • Systems Engineering and Multidisciplinary Design Optimization.

The application areas we have considered include:

  • Small Satellite Development and Operation;
  • Spacecraft Systems and Subsystems Design;
  • Satellite Constellation Design;
  • Mission Concept Design for Human/Robotic Space Exploration;
  • Astrodynamics/Space Situational Awareness.

Director: Prof. Koki Ho

Koki HoDr. Koki Ho is an assistant professor at the Department of Aerospace Engineering of the University of Illinois at Urbana-Champaign (UIUC). Prior to that, Dr. Ho was a research assistant professor at the University of Illinois at Urbana-Champaign (UIUC) and a visiting researcher at NASA Jet Propulsion Laboratory. Dr. Ho is also the Chair of the AIAA Space Logistics Technical Committee.

Dr. Ho received his Ph.D. degree in the Strategic Engineering Research Group at the Department of Aeronautics and Astronautics of the Massachusetts Institute of Technology (MIT) in 2015. Dr. Ho received his Bachelor’s and Master’s degrees in the Intelligent Space Systems Laboratory at the Department of Aeronautics and Astronautics of the University of Tokyo in 2009 and 2011 respectively.

Dr. Ho’s PhD research developed a dynamic network optimization methodology for interplanetary supply chain management. The developed method performs high-level lifecycle optimization of space mission sequences and find an optimal space transportation architecture considering its technology trades over time. The application cases include human Mars and Asteroid exploration.

Dr. Ho has multiple flight project experiences including a small satellite Nano-JASMINE at the University of Tokyo, and a mercury spacecraft Bepi-Colombo when he interned at Airbus Defense and Space (formally EADS-Astrium) in Germany from September 2010 to March 2011.
