He (Jackie) Feng Feng
I joined the University of Iowa as a Postdoctoral Researcher in September 2024 after earning my Ph.D. from the University of Maine in December 2023. My research focuses on rheology, structural geology, rock microstructures, and the chemical-mechanical processes associated with deformation. I approach questions using field observations chemical and microstructural microanalysis, and numerical modelling. I specialize in microanalytical techniques, including SEM (EDS, EBSD, & CL), EMPA, and LA-ICP-MS.
Research Interests:
- How can we characterize the rheological behaviors of different regions of the lithosphere?
- How do strain localization and plate boundaries initiate and develop?
- How do chemical processes couple with mechanical deformation?
- How does microanalysis link to plate tectonics?
- How can we integrate diverse instruments and techniques for textural and chemical microanalysis of earth materials and establish innovative protocols?
- Current Work and Interests:
- Developing high-resolution heavy mineral analysis using diverse analytical techniques;
- Establishing laboratory protocols for heavy mineral characterization;
- Linking deformed basement dynamics with heavy mineral and provenance analysis of sedimentary cover.
Currently, I work with Dr. Emily Finzel, expanding my expertise in heavy mineral analysis and provenance studies, with a focus on integrating advanced analytical techniques to investigate sedimentary processes, chemistry and tectonic evolution.
