RESEARCH EXPERIENCE
I. Current research projects, cooperating with colleagues in
Stanford University, University of Florida, Indiana University,
University of Michigan, and several research institutes in China:
- Study the fossil angiosperms of the Early Cretaceous (about
135 million year old), western Liaoning Province, China.
- Study early angiosperm specimens of the Later Jurassic, from
China.
- Study some angiosperm-like specimens of the Middle Jurassic,
from Liaoning Province, China.
- Tracking the origin of angiosperms through investigating fossil
molecule oleanane in fossil plants or petroleum samples from Middle
Jurassic and Upper Triassic, northwestern China.
- Further investigation of fossil molecule oleanane in gigantopterids
from China.
- Anatomical study of reproductive organs of gigantopterids.
- Leaf architectures of Gigantopteridales and their significance
- Gigantopterid biome
- Study of permineralized cycad plants from Permian, China.
II. Research at Indiana University Southeast (1996-2000)
1. Anatomy and morphology of Gigantopteridales
2. Cladistic analysis of Gigantopterids
3. Molecular fossil record of oleanane from Gigantopteridales
of China
4. Investigation of oleanane in living anthophyte plants
5. Study of a permineralized cycad plant from Permian of China.
III. Graduate Research at the Ohio State University from 1992
to 1996:
1. Field trip for collecting fossil plants in Guizhou Province,
China
2. Department Chairman's Assistant in organizing administrative
data
3. Dissertation Research
IV. Research at China University of Mining and Technology from
1985 to 1990:
- Wrote the General Introduction in the "Summary of Coal-Field
Geologic Rules of China", a video program edited by B.
Tian et al., a project funded by the Coal Ministry of China,
1988.
- Participated in "Analysis of Sedimentary Coalification
Environment of Upper Permian in Yunnan, Guizhou, and Sichuan
Provinces," a project funded by the Coal Ministry of China,
1986-87.
- Head of field team for an investigation, "Research on
Carboniferous Biostratigraphy in Hunan Province," a project
funded by the Coal Ministry of China, 1985-86.
