Dr. Ricardo FernandesResearch Group Leader
Ricardo employs complex systems theory to better understand patterns of historical causation so that acquired knowledge can make a useful contribution to modern-day policymaking and risk analysis. Among others, he is investigating the impact of human agency in shaping historical trajectories, human-environmental interactions, the interplay between socioeconomic inequality and societal stability, and the emergence and spread of new technologies.
Ricardo is currently Group Leader in Systems Archaeology, Head of the Radiocarbon and Computational Labs, and co-Head of the Compound Specific Isotopic Analysis Lab at the Department of Archaeology. His methodological research follows three main themes:
Big Historical Data. Ricardo founded and oversees the development of the Pandora & IsoMemo database networks. These follow a non-hierarchical distributive model under FAIR and CARE principles. To accelerate the process of data gathering Ricardo is also working on artificial intelligence methods employed to retrieve data from unstructured sources.
Scientific analysis of material remains. Fundamental research on radiocarbon and single compound isotopic methods aims at improving the diversity and quality of information that can be retrieved from archaeological materials. These methods are then applied to diachronically reconstruct past human lifeways, productive activities, and paleo-environmental/climatic conditions.
Modelling and machine learning. Novel open-source modelling tools are developed to analyse historical data and made available via the Pandora & IsoMemo software platform. In particular, Bayesian modelling is employed to build complex hierarchical models able to integrate diverse sources of information. Data-driven and hypothesis-driven approaches are both employed to investigate historical causation. This includes the use of a variety of machine learning methods.
Ricardo Fernandes has a Bachelor's degree in Physics from Porto University (Portugal) and a Master’s degree in Geoarchaeology with a Minor in Mediterranean and Near East Archaeology from the Vrije Universiteit in Amsterdam (The Netherlands). He concluded summa cum laude his Ph.D. in Natural Sciences at the University of Kiel (Germany).
