Om mig

I obtained my PhD in 2014 from Uppsala University in developmental neuroscience. In my PhD-thesis I demonstrated that subpopulations of neuronal progenitor cells have innate properties that make them sensitive to tumor development. This illustrates the importance of understanding the heterogenic properties of developing tissues and relation to neoplastic formation. Following my PhD, I started a dual Post doc training in the group of prof. Lars Ährlund-Richter at Karolinska Institutet and in the group of Dr. Jan Mulder at SciLifeLab Karolinska Institutet. The research focused on a novel transplantation model for studying pediatric solid tumors together with a novel MULTIPLEX technique for enhanced correlation analysis of multiple cellular markers at the site of tumour metastasis. In September 2019 I obtained an Assistant Professorship at Karolinska Institutet.

Forskningsbeskrivning

Currently the mechanisms underlying therapy outcomes are largely unknown, but both genetic and non-genetic components have been implicated. Data from us and others have indicated that distinct protective cell cycle-phases may play a significant role for chemotherapy-resistance, with poorly understood mechanisms. Furthermore, the microenvironment has been suggested to influence the cell cycle profile. This is of outmost importance since most tumours respond to first-line therapy and can even be brought to complete clinical remission, but local and systemic relapse remain a major therapeutic challenge, urging the need for novel in vivo models representing homologous (i.e. human-human) signalling, when investigating therapy resistance and regrowth. For this a novel transplantation model for studying pediatric solid tumors is used. The model differs from existing ones in that it includes a human environment for tumor growth. The approach has been shown to be especially applicable for tumors originating early in life, allowing precise and more clinically relevant mapping of the events of clonal selection leading to therapy-resistance and relapse.
