Aim: Investigate the role of SBDS in ribosome homeostasis. I designed the study and experiments, analyzed the data, and wrote the papers.

Aim: Develop methods to expand autologous hematopoietic stem cells from Shwachman-Diamond syndrome patients to provide sufficient numbers of cells for mutational repair and for improved engraftment. I designed the experiments and analyzed the data.

Aim: Investigate whether short telomere length is associated with immunologic dysfunction in patients presenting with and without marrow failure. I clinically phenotyped patients with marrow failure for this study and recruited study subjects.

Aim: Utilize spermatogonial stem cell (SSC) transplantation to generate a canine model of Fanconi anemia. I served as administrative PI for this multi-PI grand and designed the experiments and analyzed the data for my project.

Aim: Examine the role of translational control of gene expression in a ribosomal disorder contributing to leukemogenesis via marrow stromal cell dysfunction. I designed the study and experiments, analyzed the data, and wrote the papers.

Aim: Utilize engineered homing endonucleases to correct the mutations causing the inherited bone marrow failure syndrome Shwachman-Diamond syndrome (SDS) in SDS patient-derived iPS cells. I designed the study and experiments, analyzed the data, and wrote the papers.

Aim: Establish a patient registry of clinical data and biological specimens to characterize the longitudinal natural history and molecular biology of Shwachman-Diamond syndrome. I organized and directed Registry activities.

Aim: Characterize the hematopoietic phenotype of a mouse model of SDS. I designed the study and experiments, analyzed the data, and wrote the papers.
