Research Technician III, Cellular and Molecular Medicine

This Research Technician III, Cellular and Molecular Medicine position is with University of Arizona in Tucson, AZ. Conduct laboratory experiments with minimal supervision, including: Maintain, expand, and quality-control human iPSC lines, including thawing, passaging, cryopreservation, and mycoplasma testing; troubleshoot culture problems such as contamination, spontaneous differentiation, or poor viability, and recommend corrective actions to the PI. Differentiate hiPSCs into cardiomyocytes and other cardiac lineages, including epicardial, fibroblast, and endothelial cells; characterize and validate differentiated cell populations. Perform functional phenotyping of iPSC-derived cardiomyocytes using calcium imaging, contractility measurements, and related functional assays, and determine whether data meet quality criteria before analysis. Perform molecular and cell biology assays, including RNA and protein isolation, qPCR, Western blotting, immunofluorescence, and microscopy, and troubleshoot assay failures. Maintain mouse colonies for laboratory research, including: Plan and track breeding schemes and wean litters to maintain experimental lines. Genotype mice and determine breeding and experimental assignments from results. Harvest tissues for molecular and histological analysis. Perform physiological assessments on study animals Record-keeping, Analysis, and Presentations: Communicate experimental progress, problems, and results to the PI and laboratory staff. Maintain accurate, detailed records of experiments and results, and enter data into laboratory databases. Catalog specimens and samples. Analyze and interpret experimental data independently and present findings to the PI. Operational Support: Orders and catalogs laboratory supplies and supports laboratory operations.
