Research interests

In recent years, I have focused more on administrative activity. I have overseen the ongoing collaborative effort to create and manage the Mount Horeb Research Collections and Education Center. Still very much a work in progress, the Education Center has the potential for not only housing our extensive collections of physical materials—mineral exploration and engineering drill core, sample sets from public and private water-wells, and hand-size samples of rocks from all across the state—but also including a modern educational facility capable of providing enhanced educational outreach regarding Wisconsin geology to our clients and customers. My recent effort in the administration area is to lead the Survey in the development of an archival plan to preserve the many sets of data and information that are a part of the WGNHS legacy and to help ensure the availability of such information for many years.

I also continue to work in geology; I mapped the geology of La Crosse County several years ago and have worked with colleagues in mapping the buried bedrock surface of southeast Wisconsin. Most recently, I mapped the bedrock geology of Pierce County and completed a STATEMAP funded mapping project (initiated by a former colleague), the bedrock geology of Pierce and St. Croix Counties, Wisconsin.

I have always been interested in complex resource policy issues and the way such issues affect the general public. In my time with the Survey, I have worked extensively on metallic mining—its regulation at the state and local levels of government and the impact of metallic mineral exploration and development on Wisconsin citizens—and on the policy aspects of federal and state relationships regarding the management, storage, and disposal of high-level radioactive waste. Such complex resource policy issues invariably are controversial and can be divisive, and I am engaged in Extension’s role as a source of objective information as a means to empower citizens, government groups, and industrial interests in resolving conflicts related to these kind of issues.

I also am interested and active in working on in the tenure process and its documentation as well as how the faculty of UW-Extension engage with the broad issues of scholarship.

Recent collaborations

As a part of my mapping in Pierce County, in 2006 and 2007 I collaborated with Bill Cordua of UW-River Falls in pulling together geologic, geochemical, and geophysical data related to the Rock Elm complex, a meteorite impact structure in east-central Pierce County.

In 2005 I worked with James Lesser, University of Wisconsin–Extension Distance Education/Digital Media Unit, and James M. Robertson to develop the DVD “It all starts here,” which describes and documents the value and use of the physical materials contained within Survey research collections.
