  of hidden weapons and other threats
• Contact-free detection and identification
  of explosives, illicit drugs and other
  dangerous substances even through packaging
• Characterization and quality control of materials
• Biomolecular and biomedical studies

Skills

• Strong spectroscopic experience
• Hardware and software (signal processing) design and development
• Numerical modeling and simulation
