Most of the people have no choice about being poor, this decision comes with the cradle. Due to my life experience I consider that it is my duty to work for them, so that they can have the same opportunities in life, independently of the birth conditions. I am an economist and an industrial engineer. With them I have been able to work in diverse projects (in the health area) that promote this equality. Yet, each time I found more differences between the assumptions in which economic theory is made and the developing world. In my MPhill I worked to understand better the statistical tools so that now, in the PhD, I can build theory, based on network models, to understand how the development of a region cannot be studied alone, but it should be embedded within its geographical context. In this way, with my study, I want to help in the construction of better public policies.
