Postdoctoral Research Scientist

Responsibilities

• Design and implement a 1D OAE process-model testbed within the C-Star modeling system to allow rapid prototyping and iteration.
• Develop generalized representations of sinking particulate material, including parameterizations for mineral dissolution, precipitation kinetics, and sinking velocities.
• Calibrate representations of particles generated via electrochemical and mineral alkalinity addition in collaboration with industry partners.
• Run large perturbed-parameter ensembles to explore parameter space and assess uncertainty in OAE-relevant outcomes.
• Validate parameterizations against empirical laboratory and field datasets.
• Implement process formulations within the ROMS-MARBL framework to ensure portability to 3D configurations.
• Contribute to C-Star software infrastructure, including documentation and reproducibility standards.
• Submit peer-reviewed manuscripts documenting calibration, validation, and scientific findings.

Requirements

• Ph.D. in oceanography, marine chemistry, geochemistry, chemical oceanography, or a closely related field.
• Strong background in ocean biogeochemistry, including carbonate chemistry, alkalinity, and marine carbon cycling.
• Familiarity with marine mineral dissolution/precipitation kinetics and/or particle dynamics.
• Proficiency in scientific software development using Python.
• Experience working with biogeochemical model code (Python, Fortran, or Julia).
• Ability to design systematic numerical experiments and communicate findings clearly.
• Collaborative disposition for working with both academic researchers and industry stakeholders.

Preferred Qualifications

• Experience with MARBL or a comparable marine biogeochemistry library, including ROMS-MARBL coupling.
• Prior research on OAE, mineral weathering, or alkalinity-modifying processes.
• Experience developing, calibrating, or validating numerical models.
• Laboratory or field experience with OAE experiments or marine carbonate chemistry measurements.
• Familiarity with Bayesian calibration methods, ensemble parameter estimation, or uncertainty quantification.
