Marianna Cortese


Dr. Cortese obtained her medical degree in 2013 from the University of Heidelberg in Germany. She completed her Ph.D. in Epidemiology in 2017 at the University of Bergen in Norway, in which she focused on risk factors and early signs of multiple sclerosis.

In 2018 to 2019, she joined Dr. Ascherio’s Neuroepidemiology Research Group at the Department of Nutrition for her postdoctoral research training and has since continued working with his team, currently as a Research Scientist, on understanding risk factors of the onset and progression of multiple sclerosis and other neurodevelopmental and neurodegenerative diseases using large prospective cohorts, such as theNurses’ Health Studies, the US military cohort, the Finnish Maternity Cohort, the BENEFIT trial follow-up cohort, and the Medical Birth Registry of Norway.

Dr. Cortese is currently focusing on a unique project identifying a metabolomic signature of MS progression using blood of MS patients collected in the earliest disease stages. She is also investigating new risk factors of MS and examining the immune response to different viral infections using blood samples from the large cohort of active duty personnel in the US military. Finally, Dr. Cortese is working on projects on prenatal risk factors for neurodevelopmental and neuropsychiatric diseases using Norwegian population registries.

PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
