Welcome!

This is the webpage of Thomas Stiehl. I am mathematician and medical doctor. In my research I develop mechanistic mathematical models with applications in the biosciences. My focus is on cancers of the blood forming system, such as acute myeloid leukemias (AML) and myelodysplastic syndroms (MDS). The models help to better understand disease mechanisms and to predict the course of the disease based on clinical data. This is a first step in the adaptation of treatments to disease characteristis of indiviual patients (personalized medicine).

Research

Areas of focus:
  • Mathematical modeling of stem cell dynamics and disease progression in blood cancers (AML, MDS, MPN), including the role of clonal selection/clonal competition, systemic feedback-mechansims and processes in the stem cell niche.
  • 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 stroma cells.
  • Mathematical modeling of neurogenesis in the adult brain.
  • Mathematical modeling of stem cell dynamics in plant meristems.
