We invite applications for a postdoctoral position at UNICID to work on galaxy evolution using JWST data from the CEERS, JADES, and NEP surveys. The successful candidate will contribute to a number of interconnected research projects aimed at understanding the mass assembly and chemical enrichment of galaxies across cosmic time. At intermediate redshifts, we will provide a first-order estimate of the fraction of ex-situ stellar components in galaxies by applying spectral fitting techniques to LEGA-C data, searching for deviations in the stellar mass–metallicity relation. These studies will be complemented by proposals for integral field spectroscopy, allowing spatially resolved analysis of stellar metallicity as a tracer of galaxies' assembly history. At higher redshifts, the focus will be on JWST-CEERS data to extend morphological classification to galaxies up to z∼8, enabling the study of structural features at early cosmic times. In parallel, we will conduct a detailed analysis of stellar population parameters at high redshift, evaluating current model limitations and comparing results from spectral and SED fitting approaches.

Qualifications:
 Applicants should have a strong background in data analysis, statistics, and galaxy evolution, with demonstrated proficiency in Python programming. Experience with spectral fitting, SED modeling, and large survey datasets will be considered an asset.

Fellowship Details: The position is funded by FAPESP and includes:

• Annual tax-free stipend of R$ 144,000 (Brazilian reais)
• Research grant of R$ 14,400 per year
• Relocation assistance
• Additional funding for travel to conferences

How to Apply:
 Interested candidates should send the following documents to rrdecarvalho2008@gmail.com or b.barbuy@iag.usp.br by September 30th, 2025:

• Curriculum Vitae
• List of publications
• Brief research proposal (1–2 pages)


We encourage early applications. Review of applications will begin immediately and continue until the position is filled.
