Job description

Integrated Assessment and Climate Change (IACC) RESEARCH GROUP

BACKGROUND

The Energy, Climate, and Environment (ECE) program at IIASA is searching for a Researcher (R1)/ Research Scholar (R2) to work in the Pathways workstream within the Exploring Real Zero project, and related research efforts. The workstream develops a new generation of mitigation pathways that minimize residual gross emissions by capturing real-world innovation across three leading integrated assessment models.

The successful candidate will work closely with the Pathways workstream co-leads on the identification and quantification of the innovation gaps that account for residual gross emissions in current mitigation scenarios, coordination and implementation of the modelling teams, and the cross-model synthesis comparing new pathways with the existing literature.

MAIN tASKS AND RESPONSIBILITIES

In the following items, we deliberately use the words “contribute” to and “develop” to respectively distinguish between the more supportive role of Researcher (R1) and independent role of Research Scholar (R2).

• Contribute to / lead the cross-model innovation gaps analysis: design and run the survey across modelling teams, maintain the ranked gap inventory, and quantify residual gross emissions by sector and gap across three global IAMs
• Contribute to / develop the analytics around the modelling protocol: diagnostic checks of scenario submissions against the protocol, and documentation of harmonized assumptions and remaining differences across models
• Contribute to / develop the cross-model synthesis comparing new pathways to the existing literature, including preparation of scenario submissions to the Scenario Compass Initiative and FAIR publication of scenario data
• Support the embedding of methodological guardrails (technology scale-up rates, carbon dioxide removal, CO2 storage, justice) into scenario parameterization and design across the modelling teams
• Contribute to the implementation of model advances in MESSAGEix alongside the sectoral modelling team, as the division of gap-closure work permits
• Support scenario extractions and analysis for national fossil fuel phase-out roadmap development
• Process multi-model scenario data (IAMC format) into consistent indicators, figures and statistics, with version-controlled, reproducible code
• Contribute to / lead written outputs, including reports and scientific papers
• Present methods and results to technical and non-technical audiences

SKILLS, QUALIFICATIONS & EXPERIENCE

Education and Background

• Master's (R1) or PhD (R2) degree in energy systems, climate or environmental science, engineering, economics or a related field
  Essential skills and competencies:
• Knowledge of integrated assessment modelling and mitigation scenario analysis, including the scenario literature on residual emissions, carbon dioxide removal and carbon capture and storage
• Proficient programmer, with experience in Python for data analysis (e.g. pandas, pyam) and reproducible, version-controlled workflows (git)
• Experience with IAMC-format scenario data; hands-on experience with an integrated assessment modelling framework (e.g. MESSAGEix, REMIND, GCAM) is a plus
• Demonstrated experience of writing up methodologies and results in reports, scientific publications and/or policy-relevant materials
• Fluency in English and good presentation skills
