Research interests

My research activity can be grouped into four main areas:

1) Application of Taylor differential algebra and Taylor models to space engineering problems

  • Robust and optimatl guidance and control laws of space trajectories
  • High-order expansion of two point boundary values problems
  • Rigorous global optimization of interplanetary transfers with multiple gravity assists and deep-space manoeuvres
  • Orbital conjunctions and collision probabilities for NEO and space debris (see Figure 1)
  • Orbital determination of asteroid and artificial satellites

2) Multidisciplinary optimization of space systems

  • Multidisciplinary optimization of space vehicles involved in atmospheric manoeuvres: launch; aero-gravity assist; aerocapture (see Figure 2); entry, descent, and landing
  • Coupled trajectory and spacecraft subsystems optimization
  • Design of active space debris removal devices

3) Space trajectories optimization

  • Formation flying reconfiguration and station keeping manoeuvres
  • Impulsive and low-thrust transfers in the two- and three-body dynamics (see Figure 3)
  • Aero-gravity assists and aerocapture trajectories optimization
  • Lunar and planetary landing

4) Small body sampling

  • Scientific use of the sampler, drill, and distribution (SD2)
  • Strategies for the mechanical characterization of cometary soil
  • Simulation of small body sampling via Discrete Element Method (see Figure 4)
