LabMAM at the Pontifical Catholic University of Rio de Janeiro (PUC-Rio) is offering a fully funded PhD position in the Graduate Program in Chemistry, with enrollment scheduled for the first semester of 2026. The research project focuses on developing new isotopic proxies to identify sources of polycyclic aromatic hydrocarbons (PAHs) in aquatic systems, specifically in the Amazon River mouth region. The project aims to validate the use of stable isotopes of carbon (δ¹³C), hydrogen (δ²H), and sulfur (δ³⁴S) in individual PAH compounds to distinguish between those derived from biomass burning and those from fossil fuel combustion. Applicants should have a Master's degree in Chemistry, Oceanography, or related fields, and experience in Environmental Analytical Chemistry, including chromatographic techniques and GC-MS analysis. Interest in method development using GC-IRMS and willingness to participate in fieldwork in the Equatorial Margin are desirable. The position includes a doctoral scholarship, and there is no application fee. Applications are open from September 4 to November 24, 2025.
