Magnus Tobiasson group - Biological and clinical aspects of the myelodysplastic syndrome

The Magnus Tobiasson research group is studying biological and clinical aspects of the myelodysplastic syndrome (MDS).

About our research

The main focus of the group is to implement new genetic tools in the management of patients with MDS during the transplantation process. Magnus Tobiasson is coordinating the Nordic MDS group study NMDSG14B. The research is aimed at developing and evaluating individual minimal residual disease (MRD) markers for early detection of relapse after allogeneic stem cell transplantation. The study has generated several spin-off projects such as evaluation of MRD on sorted stem and progenitor cells, and evaluation of the importance of achieving clonal reduction prior to transplantation.

Magnus Tobiasson is MD, PhD, a clinical hematologist and a translational researcher within the field of myelodysplastic syndrome and other myeloid malignancies.

Group members

Carolin Lindholm joined the group as PhD student in 2019. She studied medicine at Karolinska Institutet, and is currently working as a resident doctor in hematology at Karolinska University hospital. Her research focus is in myelodysplastic syndromes, mainly on the transplantation process and MRD markers.

Joel Wiggh became a PhD student in September 2020. He is a resident doctor in Hematology at the Karolinska Universital Hospital in Huddinge.

The aim of Joel's research at MedH is to increase the knowledge on how a patient’s unique genetic profile can be used to guide treatment before allogenic stem cell transplantation. The overall goal is to implement individualized pre-transplantation treatment for patients with Myelodysplastic Syndrome and consequently improve their prognosis.
