Research interests

As the state of the art of computing technology advances, computer-based machines are starting to perform  new tasks in less structured and less predictable environments. Possible scenarios include autonomous robots able to operate in natural environments or pro-active computer programs designed for automatic knowledge extraction from data. My research goal is to collaborate in the development of theory and algorithms that facilitates the creation of these adaptive or "intelligent" machines.
