Institute for Computational Biomedicine and Disease modelling with focus on phase transitions between phenotypes

Prof. Dr. Thomas Stiehl

Thomas Stiehl’s research focusses on stem cell dynamics in homeostasis, regeneration and cancer. He develops mechanistic mathematical and computational models to understand the development and progression of stem-cell-driven diseases. His main field of research are malignancies of the blood forming (hematopoietic) system, such as acute myeloid leukemia (AML), myelodysplastic syndromes (MDS) and myeloproliferative neoplasms (MPN). The models help to unravel the determinants of disease progression based on clinical data. Main research topics include:

  • Mathematical modeling of stem cell dynamics and disease progression in blood cancers (AML, MDS, MPN). The models account for the role of clonal competition, systemic feedback-mechanisms, treatment-related selection and stem cell – niche interactions.                      
  • Mathematical modeling of resistance development and cancer treatment.
  • Model-based risk-stratification and personalized prediction of disease progression in blood cancers.                               
  • Mathematical modeling of blood cell formation in health and disease, including reconstitution after bone marrow transplantation (recovery of blood       cell counts) and white blood cell formation in sepsis.                
  • Mathematical modeling of stem cell aging including blood-forming stem cells, neural stem cells and mesenchymal stromal cells.                  
  • Mathematical modeling of neurogenesis in the adult brain.              
  • Mathematical modeling of methylation patterns during aging and disease.

Prof. Dr. Thomas Stiehl

Thomas Stiehl studied mathematics and medicine in Heidelberg. He also received his PhD degree in mathematics from Heidelberg University. Thomas Stiehl develops mechanistic mathematical models of stem cell driven processes in health and disease. The models help to understand the patho-mechanisms underlying disease development and progression. His focus of research are cancers of the blood forming system, such as acute myeloid leukemias (AML), myeloproliferative neoplasms (MPN) and myelodysplastic syndromes (MDS). The models can be used to predict the course of the disease based on clinical data and to simulate novel treatment approaches.
