C. Renee Rohs, Ph.D. Description: C:\Users\rrohs\Desktop\My Documents\Research\Ireland and Scotland\Pictures 2010\IMG_0688.JPGNorthwest Missouri State University


In August 2000, I joined the geology faculty at Northwest Missouri State University in the Geology/Geography Department.  Since that time, the geology faculty and programs have been combined with biology, chemistry, and physics to form the Department of Natural Sciences.  Throughout my academic career, I have been committed to high quality instruction with a firm foundation in scholarly inquiry, peer evaluation, and effective delivery methods. 


The courses that I teach include Mineralogy and Petrology as well as introductory courses in the earth sciences.  At the introductory level, my purposes are to pique student interest and develop an understanding of how the earth sciences can be related to their areas of interest whether those are education, business, travel, or the environment.  Some students find that they have a passion for understanding the earth and elect to pursue a degree in geology.  These students then take the Mineralogy and Petrology sequence in their second or third year.  As with all of my courses, research activities have shaped and augmented my teaching to illustrate the importance of scientific inquiry and evaluation.


My current research efforts are focused on igneous and metamorphic rocks.  These projects have emerged from my doctoral studies at the University of Kansas and include geochronology methods using U-Pb, Sm-Nd, and Ar-Ar as well as geochemistry with ICP-MS and mineral identification using XRD.  I have supervised a number of undergraduate research projects in the St. Francois Mountains, Absaroka Mountains, Wisconsin, and Northern Scotland.  I have highlighted some information in the areas of education, teaching, supervised undergraduate research projects, research, and administrative experiences.

M.S. Geology, Kansas State University: Electromagnetic detection of saltwater in the shallow subsurface along the Saline River Russell County, Kansas


B.S. in Geology, Kansas State University




The introductory course in Petrology is offered every spring term and includes igneous, sedimentary, and metamorphic rocks.  Many of the labs used in this course have been developed from applied research projects or undergraduate research that bring together samples, thin sections, maps, and geochemical data for a holistic approach to understanding their formation.

The prerequisite course for Petrology is Mineralogy.  The introductory Mineralogy course is taught every fall and provides the foundation for additional studies in geology.  We take a systematic approach to the material by chemical groups and structures while developing a framework for identification and occurrence. 


Field Geology of the British Isles

This course, designed to pique interest by going to cool places and seeing awesome geology, was developed in 2009-10 and offered in May 2010 and 2012. The reconnaissance trip included identification and study of field sites in Ireland and Scotland vital to the development of the modern study of geology while providing compelling examples of geologic processes such as tectonic forces, economic mineralization, shoreline processes, and the expanse of geologic time.  Each field location was evaluated for impact on student understanding of geological concepts, importance to the development of the science of geology, and cultural and/or historical significance. 


Field locations included the following:

·        Coastal exposures south and east of Edinburgh to include the Old Red Sandstone and Siccar Point

Research, even at a teaching university, has been valuable to me in many different ways.  These are a few of the reasons as to why I think that research and other scholarly activities have been important during my time here at Northwest.

1.     Research has improved and enhanced my teaching.  When learning new things, it has been easier to understand my students’ perspectives and great to experience “light bulb” moments as well.

2.     While conducting different research projects, I have been actively involved in national and regional organizations including the Geological Society of America and Missouri Academy of the Sciences.  The connections and conversations that have resulted from being involved with GSA have added zest and zeal to my life as an academic scholar.

3.     Collaborative efforts between different universities have resulted from research initiatives and projects. 

4.     Involvement in research projects has helped me to prepare my students for both graduate school and employment.


During my time here at Northwest, I have worked on a variety of different research projects including several applied research projects, a couple of faculty research projects, and numerous undergraduate projects.  In some of these research projects I have been able to use funds to collect samples, prepare samples, analyze my own samples or have them analyzed.  I have been able to build into budgets, the cost of travel and analysis of rock samples for major elemental compositions, trace element concentrations, and isotopic ratios at geochemical labs maintained at the University of Kansas.  As a result, slowly and steadily, I have been chipping away at some important geological projects including the following:

·        Crustal framework

·        Igneous systems and tectonic interpretations

·        Mafic intrusions of the St. Francois Mountains

·        Metamorphic minerals and textures as evidence of metamorphic conditions

·        Meteorite studies

                    Geology/Geography Department Chair

From July 2010 through May 2012, I served as the Geology/Geography Department Chair.  A reorganization of departments at Northwest Missouri State University during the summer 2012 resulted in the Natural Sciences Department that combined biology, chemistry, geology, and physics.


Assistant to the Provost

During the 2006-2007 academic year, I served as the Faculty Assistant to the Provost with a 75% reassignment.  As the Assistant to the Provost, I prepared materials for and attended annual meetings of the academic departments in all three colleges of the university along with the Provost and respective college Dean.  These meetings gave me a unique perspective on the curricular, space, and faculty issues that we faced as a university and provided me with a better understanding of the importance of shared governance.
