Student/Faculty Research Activities
My research focuses on the magnetic characteristics of rocks and what they tell us about earth processes such as climate, deformation of rocks, and movement of tectonic plates. Six LSSU students have co-authored nationally published manuscripts or abstracts with me during the past four years. During the last five years, 20 different students have worked with me on either magnetics or geoscience education research. This activity provides students with the experience of solving complex problems in a “real world” situation and provides a high level of motivation in the sense that a product, a published abstract or paper, is within reach. Because most of my projects are collaborative, students also often have the opportunity to work with faculty and graduate students from research institutions.
Currently LSSU geology students Russell White and Andrew Barry are participating in research as part of a National Science Foundation funded collaborative project in central Australia with Drs. Laurel Goodwin and Basil Tikoff of University of Wisconsin-Madison. Geology senior Russell White traveled to Australia in the summer of 2006 as part of our field research team to collect samples for this project. This is an interdisciplinary project involving magnetic mineralogy characterization, determination of magnetic fabric shape and orientation, structural geology, petrology and geologic field mapping. LSSU students are involved in data collection in the geomagnetic laboratory at LSSU and the University of Minnesota and in the field in central Australia . Individual students will take primary responsibility for different parts of this project, with each student independently responsible for data collection, processing and interpretation and presentation of results at a national meeting. This project will give students the opportunity to be part of a scientific team and to collaborate with other LSSU students and faculty, students from the University of Wisconsin , and faculty and staff from the University of Minnesota .
LSSU geology student Shane Carley is studying the growth and evolution of continents and specifically west central Idaho , the former western edge of North America . This study is examining the processes of formation, timing and deformation of this ancient plate tectonic boundary. This is an interdisciplinary and collaborative project involving ………. Universities. Specifically, the project that involves paleomagnetic reconstructions (LSSU), field mapping (all institutions), detailed structural analysis (SUNY-Geneseo, UW-Madison), tectonic modeling (SUNY-Geneseo, UW-Madison, Mount Holyoke ) and geochronology (U of ID). During this project LSSU students worked in the field and the laboratory with faculty and graduate students from other institutions. This provides unique learning experiences and interactions that otherwise are not typically available to undergraduates. Four LSSU students previously pursued undergraduate geomag research at LSSU. All four have completed M.S. degrees; two are in Ph.D. programs and two are in industry positions.
New Mexico project
LSSU students Joe Lori and Dan LaPorte collected samples in New Mexico and Joe is now completing laboratory data collection and analysis at LSSU. The New Mexico project is a collaborative magnetic/paleontological study with Drs. Lew Brown (LSSU) and Carl Rexroad (Indiana Geological Survey). The focus of this project is understanding paleoclimate change and how it is preserved in the geologic record. Students will ultimately present their results by means of oral and/or written publications at the national level.
