Sonia Hatsue Tatumi is a Professor in the Marine Science Department at the Federal University of São Paulo, Brazil, where she has been a faculty member since 2012. She completed her ScD at the same university, her PhD at São Paulo University, Brazil, and was a Visiting Researcher Scholar at Nara University of Education, Japan, during her PhD course.
She undertook research on Optically Stimulated Luminescence (OSL) dating and dosimetry in Brazil in 1995, with pioneering dating results of sediments collected from the Amazon river and its tributaries.
Her research interests lie in the area of OSL and the thermoluminescence (TL) of crystals applied to geochronology and environmental ionizing radiation dosimetry. She has collaborated actively with researchers in other disciplines of geosciences and archaeology doing multidisciplinary work. The research main lines are: interdisciplinary studies with geoscientists in the field of paleoenvironmental changes which occurred during the Quaternary era; improving the methodology of OSL and TL dating; studies of point defects and their kinetics in the luminescence emission; and the synthesis of nanocrystalline ceramic for ionizing radiation dosimetry and its morphological and luminescence characterization.
She has published more than 80 peer-reviewed physics and journal articles and conference proceedings, and has supervised seven MSci candidates, four PhD candidates and four postdocs. She is also a referee for more than 16 international journals.
Outside of academia, Sonia likes good food, country walks and the movie theatre.
