Other (workshops, consulting, service, grants):

• Attended a one-day workshop given by Edward Tufte entitled "Presenting Data and Information," September 2003.

Visited Cummins Engines Headquarters in Columbus, IN in Summer 2003 with several other RHIT faculty members and received a short course presentation on Six Sigma.

Participated in the MAA's Professional Enhancement Program (PREP) Workshop (sponsored by the NSF) entitled "Regression Analysis: The Heart of Statistical Methodology" presented by Dick Scheaffer and Jeff Witmer in Summer 2003.

Involved in a year long consulting project with the Asphalt Pavement Association and the Indiana Department of Transportation on contractor acceptance-volumetrics. Indiana was one of the first states developing and incorporating recommended acceptance specifications into pavement contracts. A RHIT statistics major worked on this project with me as part of a special topics course in Fall 2002.

Co-chair of the 2004 Annual Rose-Hulman Undergraduate Mathematics Conference, March 19 and 20, 2004. We had a record number of 26 student presentations.

Participated as a panelist in the "Graduate Student Workshop" at the Indiana Section of the MAA Spring 2004 Meeting.

Co-chair of the 2005 Annual Rose-Hulman Undergraduate Mathematics Conference, March 18 and 19, 2005.

Received a grant from the Mathematical Association of America (through the National Science Foundation) for the annual Rose-Hulman Undergraduate Mathematics Conference, 2005.

Received a Virginia Wesleyan College Faculty Development Grant, "Development of Calculator and Computer-based Precalculus and Calculus Laboratory Workbooks," 1996.
