Master Technician

Research

I currently work with Dr. Andrew Kniss in developing sustainable weed management programs in agronomic crops, especially sugarbeet, winter wheat, corn, and dry beans.  We conduct as many as 45 field and greenhouse trials annually.  I handle the logistical aspects of the program, manage data, write reports and grant proposals, present results at conferences, as well as supervising and training students.  I also provide GPS and GIS support for the department.

Prior to working in weed science, I worked in crop physiology management, precision agriculture, cropping systems, and plant breeding.  I initiated and conducted a project of GPS mapping and development of GIS databases and maps for record-keeping and management of Wyoming agricultural research and extension centers.  This included mapping farm infrastructure and annual research locations, soil grid sampling, apparent soil electrical conductivity mapping, and obtained aerial imagery through the AEROCam program.  Software development is currently under construction by the WyGISC staff to simplify access to the data.

Before coming to Wyoming, I worked in Ohio, North Dakota, and South Dakota in soil fertility, crop rotations, variety testing, and plant breeding research.
