Paul Hendley


Born in UK, 1951.  US home is in Charleston SC.

Two Sons - Sam and Jake

Dr. Paul Hendley is the director of Phasera Ltd. based near London, UK.  He retired from Syngenta Crop Protection Inc. in 2012 after a 37-year career in the Agricultural Chemical industry.  His final industry role was to serve as a Senior Syngenta Science Fellow in Syngenta’s Product Safety function based in Greensboro NC.  Dr. Hendley received a first class honors degree in Chemistry at Leeds University in the UK and then a Ph.D. in biosynthetic organic chemistry.


Dr. Hendley’s career included 10 years at the Jealott's Hill Research Center in the UK leading metabolism and natural products research groups followed by three years in Goldsboro, North Carolina running field soil programs.  He then was transferred to Richmond, California where the majority of his research involved running very large field mesocosm, avian exposure and groundwater monitoring programs.  In 2000, he moved to the Greensboro NC Research Center and has since been largely involved in landscape level risk assessments, spatial analyses and the conduct of very large surface and ground water monitoring programs particularly associated with pyrethroid insecticides and atrazine.


Dr. Hendley has worked extensively with CropLife America and its precursor organizations and has represented the Agrochemical Industry on several government/industry workgroups.  Most significantly, he was the industry chair of the aquatic exposure team in the ECOFRAM (Ecological Committee for FIFRA Risk Assessment Methodology) program which developed Probabilistic Risk Assessment approaches for the US pesticide regulatory process.  Dr. Hendley has also served as a member of EPA's Science Advisory Panel discussing Exposure Assessment approaches.


A particular focus of Dr. Hendley's work has been the creation and development of spatial approaches to pesticide risk refinement and assessment and has championed the use of the approaches throughout the US and EU pesticide industries via working groups and presentations.  In particular he has developed approaches that unify probabilistic and spatially distributed ground and surface water exposure modeling with exposure monitoring programs to develop regulatory confidence in the increasing utility of spatial models to identify vulnerable areas and to prioritize agrochemical stewardship and mitigation programs.
