The Department of Molecular & Cellular Biology at the University of Arizona is dedicated to understanding the fundamental structures of life, exploring how biological molecules function within cells and how these processes are regulated through genetics. Our collaborative and innovative research community spans a broad range of disciplines. The Duhamel Lab studies the role of microorganisms in biogeochemical transformations, their adaptation to different environments, and their stress response.
As part of this dynamic environment, you will have the opportunity to contribute to cutting-edge research and collaborate with a multidisciplinary group of scientists advancing discoveries in biology.
The Duhamel Lab at the University of Arizona (marine microbial ecology and biogeochemistry) is hiring a part-time Research Laboratory Technician to support a newly funded, three-year National Science Foundation (NSF Biological Oceanography) project carried out in collaboration with the Charvet Lab at Susquehanna University.
The project investigates mixoplankton, which are single-celled marine organisms that can both photosynthesize like plants and eat prey like animals, and tests whether prasinophyte green algae switch from photosynthesis to feeding when phosphorus becomes scarce. The work combines continuous algal cultures, radioisotope tracer experiments (14C and 33P), flow cytometry, and transcriptomics to understand how these globally abundant organisms will respond to expanding nutrient-poor regions of the ocean.
The technician will be a core member of the experimental team, working closely with the PI (Dr. Solange Duhamel) and a postdoctoral researcher at the University of Arizona, while also helping to coordinate experiments with collaborators at Susquehanna University.
This project is expected to last up to three years, contingent on funding. The anticipated end date of the position will be determined based on the selected candidate's start date, with the possibility of extension beyond the initial term subject to continued funding and satisfactory performance.Visa sponsorship is not available for this position.
Outstanding U of A benefits include health, dental, and vision insurance plans; life insurance and disability programs; paid vacation, sick leave, and holidays; U of A/ASU/NAU tuition reduction for the employee and qualified family members; retirement plans; access to U of A recreation and cultural activities; and more!
Duties & Responsibilities- Maintain cultures of marine prasinophyte algae and bacterial prey,including media preparation and sterile technique.
- Set up, optimize, and monitor exponentially fed batch (EFB) continuousculture experiments, including characterizing growth phases of the studyspecies.
- Coordinate experiment timing with visiting collaborators and help maintain backup cultures to ensure successful sampling campaigns.
- Conduct routine sampling of experiments and assist with sample analyses(e.g., flow cytometry, cell counts and biovolume, chlorophyll, nutrient, and radioisotope uptake measurements).
- Assist the postdoctoral researcher with processing and analyzing samples generated bythe project.
- Assist the PI and postdoc with data management, record keeping, and general laboratory organization.
- Knowledge of basic microbiology and cell biologylaboratory practices, including sterile/aseptic technique.
- Knowledge of laboratory safety practices, including the safe handling of chemicals and, with…
