Postdoctoral Research Associate, Laboratory of Tree-Ring Research at University of Arizona

Location: Tucson, AZ

Cap-Exempt H-1B Position — No lottery required

**Posting Number** req25711 **Department** Tree Ring Laboratory **Department Website Link** https://ltrr.arizona.edu/ **Location** Tucson Campus **Address** Tucson, AZ USA **Position Highlights** The University of Arizona Laboratory of Tree-Ring Research invites applications for a Postdoctoral Research Associate in multi-proxy North Pacific climate reconstruction. The successful candidate will join an NSF-funded project aimed at developing multicentennial reconstructions of North Pacific climate using time series derived from long-lived bivalves (Pacific geoduck), trees, and corals. The position will also involve investigating ocean–atmosphere coupling, with particular emphasis on the propagation of tropical climate signals to higher latitudes. Under the supervision of Bryan Black, the project will be conducted in collaboration with paleoclimatologists and climate modelers at the University of Arizona and Iowa State University. *Outstanding U of A benefits include health, dental, vision, and life insurance; paid vacation, sick leave, and holidays; U of A/ASU/NAU tuition reduction for the employee and qualified family members; access to U of A recreation and cultural activities; and more!* The University of Arizona has been recognized for our innovative work-life programs. **Duties & Responsibilities** **Duties and Responsibilities:** The successful candidate will use a combination of tree-ring data, bivalve, and coral growth-increment data to generate multi-proxy, multi-centennial North Pacific climate reconstructions, integrating these reconstructions with other available marine and terrestrial paleoclimatic and ecological datasets, and contribute to collaborative analyses that link proxy records with climate dynamics. **Knowledge, Skills, and Abilities:** - Knowledge of climate reconstruction methods, with preferred experience working with growth‑increment proxy data (e.g., tree rings, bivalves, corals). - Knowledge of Community Earth System Model (CESM) outputs a
