Ana Nijnik is an Associate Professor at McGill University and a Canada Research Chair Tier II in Hematopoiesis. Together with her research team, she is studying hematopoietic stem cells and the mechanisms guiding their differentiation to all the cell lineages of the blood and immune system. A major focus of the research program is on the role of histone deubiquitinases such as MYSM1, BAP1 and others in the transcriptional and epigenetic regulation of these cells and systems. The team is also working to advance the understanding of hematopoietic stem cell function under stress conditions, such as genotoxic stress, inflammation, and infection. The work has implications for the understanding and management of bone marrow failures, hematologic malignancies, and immune dysfunction.
