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 title: " Characterization of multiple sclerosis susceptibility genes - Genetic and molecular studies in T cells".
The main objective was to understand the biological implications for the single nucleotide polymorphisms in the CLEC16A gene that show genome-wide significant associations with MS. In addition, using molecular and immunological methods, the aim has been to characterize the function of CLEC16A in human immune cell lines.

Main supervisor: Tone Berge (MSc, PhD)
Co-supervisors: Hanne F Harbo (MD, PhD) and Anne Spurkland (MD, PhD, Professor at the Department of Anatomy, Institute of Basic Medical Sciences, University of Oslo).
