Mariana started her career in Argentina, where she earned her degree in biochemistry from the University of Buenos Aires. She furthered her education at the Universitat Autònoma de Barcelona, from which she obtained both her master’s degree and PhD in molecular biology with a focus on developmental biology. During this time, she engaged extensively in omics research, which sparked her interest in bioinformatics, data analysis and machine learning. Having transferred to data science, she worked for Sky, where she honed her analytical and business skills. Mariana then joined Roche as a data scientist, concentrating on omics, biomarkers and real-world data analysis within clinical and preclinical programmes. Currently, she serves as the Research Data Insights Value Stream Lead in Pharma Research and Early Development (pRED) Data & Analytics, leading a matrix team of scientists who work on various aspects of drug development, including bioinformatics, imaging, AI/ML, scientific application development and MLOps.
