Work Model: Onsite
Status: Permanent FullTime
Hours: 37.5 hours per week
Closing Date: June 6 2025

Position Summary:

The Rabi Lab is seeking a highly motivated and experienced Scientific Associate II or III to support cuttingedge research in the field of heart transplantation. The successful candidate will contribute to preclinical investigations using rat and pig models to develop and evaluate ex vivo perfusion strategies for preserving and rehabilitating donor hearts obtained after circulatory death (DCD). This role requires proficiency in organ perfusion biochemical and molecular techniques and animal experimentation.

Key Duties & Responsibilities:

Experimental Design & Execution

• Perform and supervise ex vivo heart perfusion experiments in rodent and porcine models including organ recovery instrumentation and perfusion using both custom and commercial systems.
• Conduct functional and physiological assessments such as pressurevolume analysis echocardiography and perfusate biomarker evaluation.

Molecular & Cellular Work

• Perform biochemical assays (e.g. ATP quantification ROS enzyme activity).
• Conduct cell culture experiments with cardiomyocytes and endothelial cells derived from human and animal tissue.
• Execute molecular biology techniques including RNA extraction qPCR Western blotting and fluorescent labeling.

Animal Work

• Coordinate surgical procedures and ensure compliance with ACC/IACUC protocols.
• Support both survival and nonsurvival porcine heart transplant experiments.
• Monitor animal wellbeing and liaise with veterinary staff.

Data Management & Reporting

• Analyze data using statistical and image analysis tools (e.g. GraphPad Prism MATLAB ImageJ).
• Maintain accurate lab records and experimental logs.
• Contribute to manuscript preparation presentations and grant proposals.

Lab Operations & Supervision

• Train and mentor junior lab members and students.
• Maintain lab organization inventory and equipment functionality.
• Ensure compliance with UHN safety and biosafety protocols.

Working Conditions:

• All necessary safety biosafety and animal handling training will be provided.

Qualifications :

Education:

• PhD in Physiology Biomedical Engineering Molecular Biology Transplant Immunology or a related field.

Experience:

• For SAII: Minimum 3 years of handson research experience.
• For SAIII: Minimum 5 years with demonstrated leadership or supervisory responsibilities.
• Demonstrated experience with rodent and/or large animal models
• Some prior large or small animal surgical skills is encouraged.
• Handson experience with ex vivo perfusion systems (ideal not absolutely necessary).
• Expertise in biochemical assays molecular biology and mammalian cell culture is required.
• Familiarity with therapeutic modalities such as siRNA delivery metabolic interventions or gene editing is an asset.

Skills:

• Strong analytical and troubleshooting skills.
• Excellent communication and organizational abilities.
• Ability to work independently and collaboratively in a fastpaced research environment.
• Proficiency with data analysis software and Microsoft Office Suite.
