Dr Sharon Lehany


Dr Sharon Lehany has a PhD in genetics and molecular biology from the University of Cambridge. Sharon spent twelve years as a public servant with what is now the Ministry for Primary Industries, working on scientific and strategic policy as both an analyst and a manager. Over that time she worked extensively with the HSNO Act, particularly on the practical and policy implications of how it is implemented for new organisms. She was also one of the architects of the significant package of amendments to the HSNO Act in 2003, which represented the then-Government’s response to the Royal Commission on Genetic Modification.

Since moving on from the public service, Sharon has moved into the non-profit sector and chairs the charitable trust Active Minds Aotearoa, which promotes science literacy and science education within the Manawatu region. She also provides consultancy services to science sector organisations and other science related services to government and industry good organisations.
