Job Description

Requisition Id 13647 

­­Overview:

As a U.S. Department of Energy (DOE) Office of Science national laboratory, ORNL has an extraordinary 80-year history of solving the nation’s biggest problems. We have a dedicated and creative staff of over 6,000 people! Our vision for diversity, equity, inclusion, and accessibility (DEIA) is to cultivate an environment and practices that foster diversity in ideas and in the people across the organization, as well as to ensure ORNL is recognized as a workplace of choice. These elements are critical for enabling the execution of ORNL’s broader mission to accelerate scientific discoveries and their translation into energy, environment, and security solutions for the nation.

The Computational Hydrology and Atmospheric Science Group (CHAS) at the Oak Ridge National Laboratory (ORNL) is seeking a qualified postdoctoral candidate in the fields of Hydrological and Earth System Modeling and Artificial Intelligence (AI) with a strong background in computational sciences, statistics, hydrological modeling, and Earth system modeling. ORNL’s CHAS group conducts world-class research and development in hydrological and Earth system modeling, large scale data analytics and machine learning (ML), and model-data integration at the US Department of Energy’s (DOE’s) Leadership Class Computing Facilities (LCFs).

Major Duties/Responsibilities:

• Work with the AI research team to develop ML and data analytics algorithms, including physics-informed AI, explainable AI, causal AI, and uncertainty quantification (UQ) methods for advancing hydrological and Earth system modeling.
• Develop computational scalability and performance of ML algorithms and large-scale hydrological and Earth system models, including the scaling of algorithms and simulation models and HPC implementations.
• Analyze multi-scale, multi-modal data, including model simulation data, in-situ observation data, and remote sensing data, and extract information from the data to inform model development.
• Collaborate with a diverse team of hydrologist, Earth scientists, and computational scientists, both within the CHAS and across DOE Labs and partner universities, to apply AI/ML algorithms aimed at enhancing predictive understanding of the Earth system.
• Develop physics-informed ML algorithms, including effective and realistic surrogate modeling and physics-data-integrated hybrid modeling.
• Publish research in peer-reviewed journals and present results at national and international conferences.
• Deliver ORNL’s mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service. Promote diversity, equity, inclusion, and accessibility by fostering a respectful workplace – in how we treat one another, work together, and measure success.

Basic Qualifications:

• A Ph.D. in water resources, hydrology, earth system science or computational sciences or a related field completed within the last five years.
• Research experience in AI/ML and hydrological modeling.
• Experience in data analytics.

Preferred Qualifications:

• Knowledge of data analytics, UQ, causal inference, and AI/ML algorithms.
• Experience with simulations using the Energy Exascale Earth System Model (E3SM).
• Experience with coastal compound flooding simulation.
• Experience with the Linux operating system, LaTeX, Git, Python, and Fortran.
• Collaborative research capabilities as demonstrated by existing peer reviewed publications and technical proposals.
• Strongly motivated to perform and publish leading edge research.
• Excellent verbal and written communication skills.
