Post-Doctoral Researcher

María del Mar is a Computational Biologist specializing in Integrative Cancer Research. She completed her undergraduate studies in Biology and earned a master’s degree in Biotechnology (UGR, Spain), followed by an international PhD in Health and Wellness Technologies (UPV, Spain).

Currently, she is investigating the functional impact of germline variants in gliomas and acute myeloid leukemia with the ultimate goal of estimating cancer risk and elucidating the mechanisms behind non-coding mutations. Her scientific interests encompass a dual focus, spanning from the fundamental exploration of complex tumor nature at the molecular level to the clinical translation aimed at selecting optimal treatments for patients, with particular emphasis on immunotherapies.

To achieve this, she aims to integrate diverse biomedical data using advanced computational tools to comprehend cancer dynamics and enhance treatment selection.
