Evolution in nature and society
Data science and evolution
The main focus of my current research is on understanding evolutionary processes in nature and society in data-driven ways. In the past few years we worked a lot with the global mammalian fossil record, documenting evolutionary history of life.
The global fossil record refers documents and characterises evidence about organisms that existed at different times and places during the Earth’s history. One of the major directions in computational analysis of such data is to reconstruct environmental settings, track climate changes over millions of years and understand global change and evolutionary processes in general.
Rapidly growing global biospheric databases, such as NOW coordinated from Helsinki, aggregate and accumulate findings and knowledge that geoscientists acquired over many years. These databases are big data of palaeontology. The datasets are compiled from different sources, they are to an extent subjective, include specific biases and uncertainties, data sparseness and quality varies over time and space. These datasets are complemented by high volume and large velocity satellite observations of the modern day world, which are needed for training and calibration of predictive models, and require scalable and robust computing.
