Expert in invasive aquatic plants, soil fertility, turfgrass, potting media, composting, and utilization of composted biosolids in horticulture. Principal investigator – Invasive Aquatic Plant Program. In charge of the soil testing in New Haven. Holds state supervisory licenses in the care of trees, turf and ornamentals and aquatic weed control. Works with public to solve soil and water related problems.

Station Career:
Agricultural Research Technician I, 1979-1985
Agricultural Research Technician II, 1985-1993
Assistant Scientist I, 1993-2000
Assistant Scientist II, 2000-2014
Associate Scientist, 2014-Present

Past Research:
Survey of potting media sold throughout Connecticut, utilization of drinking water treatment plant residuals (alum sludge) as a soil amendment, effects of chlorine in water on plant growth, phosphorus and zinc fertilization of silage corn, uptake of EDB and Vorlex by radish, uptake of atrazine and alachlor by sweet corn, effects of composted lawn clippings containing 2,4-D, dicamba and MCPP on tomato, utilization of municipal and industrial composts in media for potted plants. Investigations into amendments that reduce the leaching of nitrates, phosphates and heavy metals from potting media containing biosolids compost, Studies on the effectiveness of dried biosolids from Waterbury, Connecticut as a fertilizer for turf, Use of biosolids and leaf compost for golf greens, Comparison of pulverized, granular and pelletized limestone for changing the soil pH under established turf.

Current Research:
Surveillance of invasive plants in lakes and ponds. Determine biotic and abiotic parameters governing why invasive aquatic plants occur in certain sites. Discover novel methods for controlling invasive aquatic plants with minimal impacts on the aquatic ecosystem and humans. These include documenting the effectiveness of herbicide treatments during the early spring and fall when use of lakes is minimal, winter drawdowns, biological agents such as milfoil weevils and grass carp, harvesting, and benthic/limnobarriers.
