Research Interests:

My interests are to increase the use of IPM tactics, including the use of scouting programs and the application of biorationals, to reduce insect problems in the Twin Cities. Plant stress and decline are a major problem for plant health care in urban areas. My research identifies factors that make plants susceptible to stress and cause increased insect damage.
