He (Jackie) Feng, PhD
Postdoctoral Research Scholar
Biography
Profile
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. I am also teaching Structural Geology. My research centers on rheology, structural geology, rock microstructures, and the chemical–mechanical processes associated with deformation. I address these questions through field observations, chemical and microstructural analyses, and numerical modeling. I specialize in advanced microanalytical techniques, including SEM (EDS, EBSD, CL), EMPA, and LA-ICP-MS, and am particularly interested in integrating diverse methods to develop innovative analytical protocols.

Research Interests
- Characterizing the rheological behavior of different regions of the lithosphere
- Understanding the initiation and evolution of strain localization and plate boundaries
- Investigating the coupling between chemical processes and mechanical deformation
- Linking microanalytical observations to large-scale plate tectonic processes
- Developing integrated workflows for textural and chemical microanalysis of Earth materials
Current Work and Interests
I currently work with Dr. Emily Finzel to expand expertise in heavy mineral analysis and provenance studies, with the goal of integrating advanced analytical techniques to investigate basin analysis, geochemistry, and tectonic evolution. My ongoing projects include:
