I am a clinical researcher in rare blood disorders, with a particular focus on thrombotic microangiopathies. In 2014, I co-founded and now co-direct the US Thrombotic Microangiopathies (USTMA) Consortium, with the goal of improving outcomes in these rare diseases through collaborative clinical trials and translational research. I also lead several clinical trials in these and other rare blood disorders.
