Ingvild Sørum Leikfoss has a PhD degree in Molecular Immunology from the University of Oslo from 2015, with the following title “Characterization of multiple sclerosis susceptibility genes”. She has a Master of Science degree in Molecular Biology and Immunology from the Department of Molecular Biosciences. The focus of her master thesis was in vitro characterization of the binding between Immunoglobulin G and different Fc receptors from both humans and mice.

Project/research interests
The main focus of her project is to analyze a biomarker for neurodegeneration in MS patients. She is also involved in several projects within the group and have a broad experience using different immunological and molecular laboratory techniques such as cell culturing and activation (primary human cells and cell lines), ELISA, Flow cytometry, Image stream (Image based flow cytometry), biomarker analysis, Western blotting, Chromatin Immunoprecipitation (ChIP), qPCR and cloning. Leikfoss is also a co-worker in the EU-projects MultipleMS, where she is responsible for handling and processing biological material collected from Norwegian MS patients included in the prospective part of the study, and she is a member of the projects Innovation Management Team. In addition, Leikfoss is responsible for coordinating the local MS research biobank.
