Position Summary:
A Postdoctoral Researcher position is available in the laboratory of Dr. Steven Chan at the Princess Margaret Cancer Centre. The Chan Laboratory studies the biology of acute myeloid leukemia (AML), leukemic stem cells, and clonal hematopoiesis (CH), with a strong translational focus on discovering and exploiting novel therapeutic vulnerabilities in pre-malignant and malignant myeloid cells.

This project will define the genetic and synthetic-lethal interactions of high-risk clonal hematopoiesis mutations, including TP53 and spliceosome (splicing factor) mutations, that drive the progression of CH to myelodysplastic syndromes (MDS) and AML. The successful candidate will combine genetically engineered mouse models with genome-wide and focused CRISPR/Cas9 screens to uncover context-specific dependencies in mutant hematopoietic stem and progenitor cells. The ultimate goal is to nominate new strategies to intercept high-risk clonal hematopoiesis and to prevent or treat myeloid malignancy.

Duties:

Design, execute, and analyze pooled CRISPR/Cas9 screens (genome-wide and focused) in primary cells and cell-line models to identify synthetic-lethal and genetic interactions with high-risk CH mutations.

Generate and characterize genetically engineered and transplantation mouse models of clonal hematopoiesis and myeloid malignancy, including colony management and in vivo experiments.

Construct and produce lentiviral and/or retroviral vectors for gene knockout, knockdown, and overexpression.

Perform a broad range of molecular and cellular biology techniques. , molecular cloning, qPCR, Western blotting, flow cytometry and cell sorting, and primary hematopoietic cell culture.

Analyze and integrate functional genomic and next-generation sequencing datasets in collaboration with the lab’s computational team.

Maintain rigorous, well-documented records and adhere to laboratory quality, biosafety, and animal-care standards.

Prepare manuscripts, figures, and presentations and present findings at lab meetings and scientific conferences.

Contribute to grant writing and help conceive new research directions for the laboratory.

Mentor and support graduate and undergraduate trainees as needed.
