Education: 
BS. and MS.  UW La Crosse

Primary Responsibilities/Activities:
The scientist directs research on aquatic invasive species (including: Asian carp, common carp, lamprey, zebra mussels, and rusty crayfish) that have been introduced into the Mississippi River system.  The scientist is responsible for directing laboratory and field studies dealing with the life history, ecology, and control of invasive species. The scientist is responsible for planning research, submitting proposals for funding, conducting research, and managing the programs budget.  The researcher directs activities regarding invasive species culture in the Center’s isolation and culture laboratories.

Research Interests:  

• invasive species life history and ecology
• physical, chemical, and biological control of nuisance species
• toxicology
• aquaculture
• treatment of fish diseases
• efficacy and safety of fishery drugs
• registration of fishery therapeutic drugs
• mussel propagation

Active Projects:

• Effect of water hardness on Asian carp egg hatching success (Invasive Species)
• Toxicity of antimycin and rotenone to Asian carps (Invasive Species)
• Effectiveness of moist air and Heath tray incubators in culturing lake trout eggs   
• Toxicity of BioBullets and BioBullet degradation products to zebra and unionid mussels (Invasive Species)
