D. Oliveira graduated in Marine Biology and Biotechnology from the Polytechnic Institute of Leiria, PT, (2006), has a post-graduation in Quality Management and Food Safety from Lusófona Univ., PT, (2009), a MSc in Marine Sciences from Lisbon Univ., PT, (2012) and a PhD in Marine Sedimentology and Paleoclimate from Bordeaux Univ., FR, (2017). To advance our understanding of Earth's responses to natural and human-induced changes, her research has been primarily focused on past vegetation responses to climatic forcings in regions highly sensitive to climate change. D. Oliveira initiated her scientific career in 2010 as FCT project CLIMHOL fellow, while doing her MSc (final grade 18/20). In 2013 she was awarded a FCT doctoral grant (4th among 61 applicants) to develop her work plan between IDL-Lisbon Univ., CCMAR (PT) and EPHE, EPOC-Bordeaux Univ. (FR). After PhD defense in May 2017, she earned a short-term post-doc position (Nov-Dec 2017) at Bordeaux Univ., followed by a research post-doc grant in the framework of the FCT project ULTImATum at IPMA (PT). In May 2019 started an FCT-CEECIND young researcher contract (500 selected from 4600 applicants) with CCMAR (PT) to investigate past Indian vegetation and monsoon response to climate variability. To complement this contract, in 2021 she was awarded the FCT exploratory project INDRA to focus on key glacial-interglacial cycles of the Middle Pleistocene (2021-2023).

Author/co-author of 18 publications in ISI journals since 2015, of which 3 published in major multidisciplinary scientific journals (IF >4: Climate Dynamics-first author, Quaternary Science Reviews-first author, Frontiers in Plant Science). Her work has awarded her 6 prizes, including the L’Oréal Medal of Honour for Women in Science (2017), the Alumni Career Award by Polytechnic Institute of Leiria (2023) and the Lewis Penny Medal by the Quaternary Research Association (2024), and 15 grants to participate in international scientific meetings.

Participation in 13 research projects (4 internationals, 7 nationals, 2 joint programs) and membership of the international pollen working group IODP EXP 339 and EXP 353, provided her the opportunity to establish a fruitful network of international collaborations, particularly with French, Belgium, German, South Korean, and Indian institutions. Conscientious of the importance of dissemination and outreach, D. Oliveira has been very active in this domain, participating in national and international scientific meetings with 103 presentations (45: author; 58: co-author) and in the organization of several conferences. She has also been involved in teaching, supervising students, various outreach initiatives such as IPMA-Escolas for 1st-grade students, and she is co-responsible for the scientific Paleo-Forums organization in the Marine Geology and Georesources Division (DivGM) at IPMA, PT (since 2014).
