As a Full Professor of Genetics at the University of Madeira, he has dedicated the past 20 years of his career to studying the origins and movements of human populations in Portugal and its former colonies. The goal is to trace the contribution of each to the genetic pool of current populations. Genetics offers a nearly unique contribution to uncovering which intermixtures among various ethnic groups in sub-Saharan populations might have occurred to shape the structure of the current population groups.

In parallel, he has developed an interest in historical and literary studies, particularly from the 16th to the 18th centuries. He has already published several monographs on King Sebastian and is currently completing others related to travel literature or editing chronicles of manuscripts that remain largely unknown.
