Research Associate- 3D Solar Dynamo Modeling

Clarkson University invites applications for a six-month Postdoctoral Research Associate position in computational solar physics and three-dimensional solar dynamo modeling. The appointment is expected to begin November 2, 2026, with an annualized salary of $68,000 ($34,000 for six months). The position will be supported by NSF Project #375-11200-102810 under the direction of Professor Chunlei Charles Liang.

The postdoctoral researcher will develop, verify, and apply a three-dimensional kinematic solar dynamo model based on the Babcock-Leighton mechanism. The research will focus on numerical modeling of the generation and transport of large-scale solar magnetic fields under prescribed differential rotation, meridional circulation, magnetic diffusion, and Babcock-Leighton poloidal-field source terms.

A central objective is to establish a robust computational framework capable of simulating solar magnetic-field evolution over multiple activity cycles and examining how variations in large-scale flows and Babcock-Leighton source processes influence magnetic-field generation, equatorward migration, polar-field reversal, and solar-cycle variability.

Research & Scholarly Activities
* Develop and validate a 3D global kinematic Babcock-Leighton solar dynamo model.
* Solve the magnetic-induction equation using prescribed three-dimensional velocity fields representing differential rotation and meridional circulation.
* Develop and evaluate physically appropriate representations of the Babcock-Leighton poloidal-field source, including spatial and temporal variations in active-region emergence.
* Implement high-order numerical methods for magnetic-field evolution, including magnetic diffusion and numerical control of the solenoidal constraint.
* Conduct multi-cycle simulations to investigate the generation and evolution of toroidal and poloidal magnetic fields.
* Analyze butterfly diagrams, surface radial magnetic fields, polarity-inversion patterns, polar-field buildup and reversal, and other solar-cycle diagnostics.

Computational Modeling & Analysis
* Investigate the sensitivity of dynamo solutions to differential rotation, meridional circulation, magnetic diffusivity, Babcock-Leighton source parameters, and initial magnetic fields.
* Incorporate observationally reconstructed large-scale solar flows and magnetic-field information, where appropriate, to constrain and evaluate the dynamo model.
* Develop GPU-accelerated computational capabilities for large-scale three-dimensional simulations.
* Prepare simulation datasets, visualization tools, quantitative diagnostics, and reproducible analysis workflows.

Mentorship & Training
* Provide guidance to undergraduate and graduate researchers participating in computational solar-physics projects.
* Share expertise in scientific computing, numerical methods, simulation analysis, and research best practices.
* Contribute to a collaborative and rigorous research environment within the Department of Mechanical and Aerospace Engineering.

Project & Collaboration Management
* Coordinate research activities with Professor Liang and project collaborators and communicate technical progress in a timely manner.
* Maintain research code, simulation data, documentation, and computational workflows with attention to reproducibility and accuracy.
* Contribute to research reports, manuscripts, conference presentations, and other project deliverables.
* Collaborate with researchers in solar physics, computational science, and related disciplines as project needs arise.

Operational & Professional Responsibilities
* Maintain high standards of research integrity, responsible data stewardship, and professional conduct.
* Participate in research meetings, seminars, conferences, and collaborative activities as appropriate.
* Engage in continuous professional development in solar dynamo theory, high-performance computing, and numerical methods.
* Assist with other research-related tasks and scholarly activities consistent with the goals of the funded project.
* Comply with Clarkson University policies and applicable sponsor requirements.
