The dos Santos laboratory in the Department of Oncology at St. Jude Children’s Research Hospital is seeking a highly motivated Associate Scientist or Scientist to support and advance research investigating cancer initiation and progression, epithelial–stromal interactions, and systemic influences on cancer risk.
The successful candidate will provide scientific and technical leadership for animal-model and organoid-based studies. This individual will work closely with the principal investigator, trainees, research staff, and institutional shared-resource teams to design, execute, analyze, and document rigorous experiments. The position is intended for an experienced scientist who can independently manage complex projects while also helping laboratory members troubleshoot experiments, implement new approaches, and maintain high standards of reproducibility and animal welfare.
The selected candidate will be appointed at the Associate Scientist or Scientist level, based on their experience, demonstrated scientific independence, technical expertise, and leadership achievements.
Who We’re Looking For
Demonstrated experience with mouse models and animal experimentation.
Experience with primary cell culture, three-dimensional culture, organoids, or tissue-derived experimental systems.
Strong understanding of experimental design, biological controls, reproducibility, and quantitative data interpretation.
Ability to independently plan, execute, troubleshoot, and document complex experiments.
Strong organizational and oral-communication skills.
What You Will Do
Animal Studies
Design, coordinate, and execute studies using genetically engineered, syngeneic, transplantation, and treatment-based mouse models of mammary gland biology and breast cancer.
