Turfgrass Management


  • B.S., Iowa State University, 1986
  • M.S., Iowa State University, 1988
  • Ph.D., Purdue University, 1993

Teaching Courses

  • TLMT 227 Turfgrass Management (sophomore level)
  • TLMT 229 Turfgrass Management Lab (sophomore level)
  • PGAM 229 Turfgrass Management Lab for PGAM students
    (sophomore level)

Research Interests

Reducing inputs and costs of maintaining turf across the north central United States. Current interests include understanding the biology and practical management of difficult-to-control weeds like annual bluegrass, purslane, crabgrass, goosegrass, and yellow nutsedge. Additional research focuses on establishment/renovation of turfed areas.

Extension Area of Emphasis

Provide the most current turfgrass management information to the north central United States incorporating research findings and practical experience to reduce inputs while not sacrificing turf performance. Recommendations, publications, and research updates can be found at
