Research Summary

We are interested in learning the cell fate decision processes: how does a cell know what to be and what not to be? We use three biological model systems to investigate this question. 1) Induced pluripotency (Yamanaka reprogramming). 2) Malignant transformation. 3) Hematopoietic stem cell emergence and maintenance. The long term goal of understanding the rules of cell fate decision making is to create desired cell types for cell replacement therapies and to eliminate the emergence of harmful cell types such as cancer.
