Short Bio

Maria João Fernandes Martins received her Ph.D. in Biology (Ecology) from Universidade de Lisboa in 2010 and Licenciatura in Biology from Universidade de Évora. She is an evolutionary biologist with broad research interests, ranging from sexual selection and reproductive strategies as drivers of micro- and macroevolutionary processes to ecology and taxonomy of living and fossil Ostracoda to the use of ostracods from sediments as proxies for paleoenvironmental reconstruction. Her work at ICArEHB will focus on paleoenvironmental changes on the Mozambican coast and how environmental changes impacted and were driven by human behavior.
