1 Alessandro Colombo Curriculum Vitæ Politecnico di Milano Dept. of Electronics, Information, and Bioengineering via Ponzio 34/ Milano, Italy Research Interests I work with large, complex, and hybrid systems, inventing new ways to understand their dynamics and control their behaviour. I have applied my ideas to models of electronic circuits, human and animal populations, cars and multi-agent systems.
