Research Technician III, Geosciences

The Department of Geosciences is part of the College of Science, a unit aiming to produce knowledge about earth and environmental processes and human-environment interactions at all geographic and temporal scales. Our department focuses on research and education in the nature, genesis, and history of the Earth and its crust, and the evolution of the environment and biota at the Earth's surface.

We encourage interdisciplinary approaches to research in the geosciences, both within the department and through interdepartmental programs.

The University of Arizona's Department of Geosciences invites you to apply for the role of Research Technician III. In this position, you will primarily conduct sample preparation and analysis of materials for geochronologic research conducted in the Arizona Laser Chron Center, within the Department of Geosciences. You will contribute to a wide range of research operations, including mounting geological materials for analysis using an optical microscope, tracking and ordering supplies for the mounting room, tracking customer samples and coordinating with the researchers to ensure samples arrive in a timely manner, performing mineral separation activities, including Frantz magnetic separations, and occasionally assisting in the operation of scanning electron microscope and/or mass spectrometers to generate geochronological data for ALC visitors and researchers.

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!

• Mounting detrital zircon and other accessory minerals using an optical microscope.
• Polishing sample mounts and acquire optical images. Involves cleaning of equipment thoroughly between samples to avoid any contamination is a significant component to this position.
• Ordering sample mounting and preparation supplies as needed.
• Monitoring, tracking, and recording ALC user samples as they move through the entire process from zircon extraction, mounting, SEM imaging, and isotopic analysis. This will involve corresponding with visiting researchers to ensure we are on-track for their session, and that their samples are ready to analyze.
• Performing mineral separation in a laboratory setting, including but not limited to Frantz magnetic separations, ultrasonic bath operation, heavy liquid separations, Wig-L-Bug separations, acid washing samples, and mounting samples.
• Use of personal protective equipment (e.g. safety glasses, laboratory coat, nitrile gloves, engineered ventilation hood system, etc.) required.
• Assist with the operation of scanning electron microscope (SEM) and/or mass spectrometers/excimer laser systems to acquire geochronologic and/or geochemical data for the Arizona Laser Chron Center researchers.
• Perform basic data reduction using in-house MATLAB protocols to evaluate quality of data.
• Training students and visiting researchers on how to mount, polish,and image samples.

• Knowledge of U-Pb geochronology, especially as it pertains to detrital zircon geochronology.
• Knowledge of the operation of mass spectrometer, excimer laser, and scanning electron microscope (SEM).
• Ability to follow laboratory safety protocols and maintain a clean work environment to prevent sample contamination.
• Ability to accurately track, organize, and document samples and laboratory records.
• Ability to communicate effectively with students,…
