The successful candidate will work under the supervision of Prof. Colin Zarzycki and contribute to a multi-institutional team. The postdoc will play a central role in developing and applying global AI/ML Earth system emulators and regional downscaling techniques to generate large ensembles of physically credible extreme weather scenarios for water and energy system risk assessment. **RESEARCH FOCUS** The postdoc's work will include: - Evaluate where global AI/ML emulators (ACE-E3SM, FourCastNet, NeuralGCM) credibly reproduce extreme weather characteristics and where physics-based models remain necessary - Combine physics-based simulations, existing model archives, and certified AI/ML emulation to build libraries of decision-relevant extreme events - Develop and apply machine learning clustering techniques to distill large event libraries into representative scenario sets and event archetypes - Generate large ensembles of spatially coherent, temporally compounded hazard scenarios at testbed-relevant scales - Work with hydrologic, energy, and urban impacts teams to ensure scenarios are suitable for downstream applications **KEY RESPONSIBILITIES** AI/ML Model Application and Evaluation - Deploy and analyze outputs from global AI/ML weather and climate emulators, including multi-decadal free-running simulations - Apply process-oriented diagnostics (e.g., TempestExtremes) to evaluate emulator fidelity for extreme precipitation, atmospheric rivers, tropical cyclones, and extratropical cyclones - Compare AI emulator outputs against physics-based benchmarks (E3SM, SCREAM) and observations - Apply regional AI/ML downscaling tools (CorrDiff, StormCast-WUS) to generate km-scale meteorological fields suitable for impacts modeling - Contribute to development and refinement of downscaling workflows across multiple testbed regions - Identify representative event archetypes spanning the distribution of extreme outcomes - Contribute to peer-reviewed publications documenting emulator evaluation, downscaling fidelity, and scenario methodology - Present results at scientific conferences (AGU, AMS) - Collaborate with multi-institutional partners on scenario development and evaluation - Participate in project workshops and cross-team coordination meetings **REQUIRED QUALIFICATIONS** - Ph.D. in atmospheric science, Earth science, computer science, physics, applied mathematics, or closely related field, conferred prior to the start date - Demonstrated experience with scientific Python programming (NumPy, Xarray, Pandas, Scikit-learn) - Experience with machine learning techniques (clustering, classification, dimensionality reduction, or emulation) - Familiarity with large climate or weather datasets and analysis of extreme events - Experience in UNIX and high-performance computing environments - Strong written and verbal communication skills - Ability to work collaboratively in a multi-institutional team environment **PREFERRED QUALIFICATIONS** - Experience with physics-based and/or data-driven climate/weather models (E3SM, CESM, SCREAM, ACE2, FourCastNet, NeuralGCM, StormCast, or similar) - Familiarity with feature-based extreme event detection and tracking - Knowledge of tropical cyclones, atmospheric rivers, mid-latitude storms and/or other synoptic-scale weather extremes - Interest in uncertainty quantification and ensemble modeling **APPLICATION MATERIALS** Applicants should submit the following materials: - Current curriculum vitae - Detailed statement of research interests and relevant experience (1-2 pages), addressing how your background aligns with the postdoc responsibilities - Contact information for three professional references **BACKGROUND CHECKS/CLEARANCES**Employment with the University will require successful completion of background check(s) in accordance with University policies.
