Current Projects

My laboratory focuses on investigating methods for expanding blood products ex-vivo. We are developing cutting-edge tools to model hematological processes that occur both in healthy individuals and in patients with hematological diseases and bloodborne pathogen infections. Additionally, we are interested in understanding how the hematopoietic stem cell microenvironment is affected under conditions of hematological malignancy.
