Erdem Caliskan
Graduate Research Assistant The University of Tennessee, Knoxville
Graduate Internship at ORNL
May 2024 - December 2024 and May 2025 - August 2025, Oak Ridge, TN
Summary: Graduate Research Opportunity (GRO) internship at Oak Ridge National Laboratory (ORNL). I work with the HydraGNN group on graph neural networks for materials science, developing surrogate models for mechanical property prediction and uncertainty-aware, multi-task learning across heterogeneous microstructures.
Mentor: Massimiliano Lupo Pasini, Computational Sciences and Engineering Division (CSED), Computing and Computational Sciences Directorate (CCSD), Oak Ridge National Laboratory
Focus areas:
- Graph neural networks for composite and polycrystalline materials
- Multi-task learning for elastic-plastic response and fatigue indicators
- Uncertainty quantification and calibration
- ML-accelerated structure–property prediction at scale on HPC systems
Selected outputs:
