Hi, my name is Clive

I am a consultant in vitro toxicologist. My expertise and knowledge is very different than other toxicologists or even other in vitro toxicologists. I create and develop your strategic business and scientific needs with you, but also follow up with tactical planning for the use and application of new approach methodologies. My considerations are based on human relevant toxicology principle and the 3Rs.

My specialty disciplines are (in vitro) dermal absorption and dermal toxicology, inhalation toxicology and microphysiological systems (MPS). I work with companies with new technologies as well as companies with products to register. I aim to connect you with partners whilst retaining their confidentiality.

I work across all industry sectors; pharma, crop protection, chemical, consumer and cosmetic.

I am a founding member and member of the Board of Directors of the North American 3Rs Collaborative and member of the MPS and regulatory subgroups. I am one of the Board of Members of the UK NC3Rs, a European Registered Toxicologist (ERT), a charted Fellow of the Royal Society of Biology and member of ASCCT, ACTC and ESTIV.

I look forward to working with you.
